Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens' products and solutions constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be
connected to an enterprise network or the internet if and to the extent such a connection is
necessary and only when appropriate security measures (e.g. firewalls and/or network
segmentation) are in place.
For additional information on industrial security measures that may be implemented, please
visit (https://www.siemens.com/industrialsecurity).
Siemens' products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends that product updates are applied as soon as they are
available and that the latest product versions are used. Use of product versions that are no
longer supported, and failure to apply the latest updates may increase customers' exposure
to cyber threats.

New contents Potential distributor
modules
Potential distributor modules are a space-
saving replacement for standard potential
distributors or potential distributor terminals.
You can set up potential groups much faster,
in a more compact design and with fewer
components than with standard potential
distributor systems.
One application is, for example, the design of
digital input modules with 16 channels and 3-
wire connection. By using the potential dis-
tributor modules, you are reserving the un-
used signal lines of antivalent sensors.
Another application is the supply of potentials
for external components.
Starting from section System
overview (Page 19)
Password provider As an alternative to manual password input
you can connect a password provider to
STEP 7. A password provider offers the fol-
lowing advantages:
• Convenient handling of passwords.
STEP 7 reads the password automatically
for the blocks. This saves you time.
• Optimal block protection because the
operators do not know the actual pass-
word.

GetSMCinfo instruction With the help of the GetSMCinfo instruction
you can respond to information provided by
the memory card in the user program and if
required, replace the memory card as a pre-
cautionary measure. This makes sense in
particular if you write to the card often in your
application, for example if you use data logs.

3.2
What are fail-safe automation systems and fail-safe modules?
Fail-safe automation systems
Fail-safe automation systems (F-systems) are used in systems with higher safety
requirements. F-systems control processes and ensure that they are in a safe state
immediately after shutdown. In other words, F-systems control processes in which an
immediate shutdown does not endanger persons or the environment.
Safety Integrated
Safety Integrated is the integrated safety concept for automation and drive technology from
Siemens.
Proven technologies and systems from automation technology are used for safety systems.
Safety Integrated includes the complete safety sequence, ranging from sensor, actuator and
fail-safe modules right through to the controller, including safety-related communication via
standard fieldbuses. Drives and controllers handle safety tasks in addition to their actual
functions.
Fail-safe modules
The key difference between fail-safe modules (F-modules) and standard modules is that they
have an internal two-channel design. This means the two integrated processors monitor
each other, automatically test the input and output circuits, and switch the fail-safe module to
a safe state in the event of a fault.
The F-CPU communicates with a fail-safe module via the safety-related PROFIsafe bus
profile.
Fail-safe motor starters
Fail-safe motor starters enable safety-related tripping of motor loads. Fail-safe motor starters
are not PROFIsafe nodes. Motor starters operate together with the fail-safe modules of the
ET 200SP system.
Area of application of ET 200SP with fail-safe I/O modules
By using the ET 200SP distributed I/O system with fail-safe I/O modules, you are replacing
conventional safety engineering configurations. This includes the replacement of switching
devices for emergency STOP, protective door monitors, two-hand operation, etc.

SIMATIC Safety F-system with ET 200SP
The figure below shows an example of a configuration for a SIMATIC Safety F-system with
ET 200SP distributed I/O system and PROFINET IO. The PROFINET IO lines can be set up
with copper cable, fiber-optic cable or WLAN.
Fail-safe I/O modules and non-fail-safe I/O modules can be combined in an ET 200SP
configuration.
The fail-safe IO controller (F-CPU) exchanges safety-related and non-safety-related data
with fail-safe and non-fail-safe ET 200SP modules.
Figure 3-3 Fail-safe SIMATIC Safety automation system (sample configuration)
Fail-safe ET 200SP I/O modules
The following fail-safe I/O modules are available for the ET 200SP distributed I/O system:
● Fail-safe power modules are used to supply the potential group load voltage and for the
safety-related tripping of the load voltage for non-fail-safe output modules.
● Fail-safe digital input modules detect the signal states of safety-related sensors and send
the relevant safety frames to the F-CPU.
● Fail-safe digital output modules are suitable for safety-related shutdown procedures with
short circuit and cross-circuit protection up to the actuator.

PotDis-BaseUnit.
• Alternatively, plug a BU cover (15 mm) on
the PotDis-BaseUnit.
With potential distributor modules, you may only
connect to the PotDis-TB versions BR-W and
n.c.-G potential, which exceed the voltage level
of SELV/PELV. Other SELV/PELV potential
groups should be separated with light-colored
PotDis BUs.
Suitable PotDis-BaseUnits are available in each
case for the different requirements. You can find
additional information in section Selecting a

PotDis-BaseUnit, plug a PotDis-TerminalBlock
in the PotDis-BaseUnit.
Voltages greater than SELV/PELV are only
permitted for the PO PotDis-TBs BR (bridged)
and NC (not connected). The same applies to
PE. Voltages at the terminals of the PotDis
modules connected to the P1/P2 rails must not
be greater than SELV/PELV.

Overview
The BaseUnits (BU) are classified according to different types. Every BaseUnit type is
distinguished by characteristics that match certain I/O modules and motor starters (see the
following table and graphics).
You recognize the BU type for an I/O module by the last two digits of an I/O module's article
number.
The BU type onto which you can plug the respective I/O module is printed on the I/O
modules. You can therefore read which BU type you need straight from the I/O module (see
Factory labels (Page 127) (page 122)).
Example: On the output module DQ 16x24VDC/0.5A ST with article number 6ES7132-
6BH01-0B
A0
the information "BU: A0" is printed. This means you can plug this I/O module to
a BaseUnit of the BU type "A0", which means on any BaseUnit whose article number ends in
"A0". I/O modules that are suitable for two BU types are labeled accordingly, for example
"BU: A0, A1".

modules

Please note:
● The potential groups opened with a light-colored PotDis-BU must not contain any I/O
modules. You can integrate any dark-colored PotDis-BUs into I/O module potential
groups provided they are based on an SELV/PELV supply.
● If you do not need the additional terminals of the PotDis-TB in a potential distributor
module, replace the PotDis-TB with a BU cover. You may only connect one potential
group within a combination of PotDis-BU and PotDis-TB.
● Only SELV/PELV potentials are permitted on PotDis-BUs. Separate different SELV/PELV
potential groups using light-colored PotDis-BUs.
● With potential distributor modules, you may only connect to the PotDis-TB versions BR-W
and n.c.-G potential, which exceed the voltage level of SELV/PELV.
● PotDis terminals are not directly configurable as PotDis via GSD/GSDML. When
configuring with GSD, always use an dummy module; with GSDML, integrate a free
space.

Electrical maximum configuration for I/O modules
The number of operable I/O modules of a potential group is limited by the following factors:
● Power consumption of the I/O modules
● Power consumption of the components supplied via these I/O modules
The maximum current carrying capacity of the terminals on the BaseUnit L+/M is 10 A.
Current carrying capacity refers to the current load via the power bus and the infeed bus of
the ET 200SP station. Consider the current carrying capacity when using a motor starter.
Maximum electrical configuration for motor starter power bus (24 V DC)
To determine the current requirement of an individual motor starter via the power bus, take
account of the following parameters:
● Current consumption via DC infeed in the ON state
● Current consumption via DC infeed when switching on (40 ms peak load)
● Increased power consumption through fan operation
● Current requirement via encoder supply of the connected DI module
The maximum current carrying capacity of the 24 V potential group is 7 A across the entire
permissible temperature range.

System Manual, 02/2018, A5E03576849-AH 49
Maximum electrical configuration for motor starter infeed bus (500 V AC)
To determine the current requirement of an individual motor starter via the infeed bus,
proceed as follows:
Calculate the current requirement via the main current paths of the individual motor starter.
In doing so, take into account the parameter Ie (set rated operational current of the motor
starter). The permissible overload characteristics of the motor feeder for motors are
determined with the thermal motor model. You calculate the current value (Iinfeed bus) for the
infeed bus of the ET 200SP system according to the following formula:
Iinfeed bus = ∑n(Ie * 1.125)
n = number of motor starters of a potential group on the infeed bus
Refer to the Manual (https://support.industry.siemens.com/cs/ww/en/view/109479973) for
details of how to assign the basic rated operational current Ie parameter.
The following values apply for the potential group of the AC infeed:
● The maximum current carrying capacity is 32 A at an ambient temperature of up to 50 °C.
● The maximum current carrying capacity is 27 A at an ambient temperature of up to 60 °C.
● The maximum current carrying capacity for applications according to UL requirements is
24 A at an ambient temperature of up to 60 °C.
Address space
The address space depends on the CPU/interface module (see CPU
(http://support.automation.siemens.com/WW/view/en/90466439/133300) Manual) and the
interface module used (see Interface module

Forming potential groups
4.5.1
Basics
Introduction
Potential groups for the ET 200SP distributed I/O system are formed by systematically
arranging the BaseUnits.
Requirements
For formation of potential groups, the ET 200SP distinguishes between the
following BaseUnits:
● BaseUnits BU...D (recognizable by the light-colored terminal box and the light-colored
mounting rail release button):
– Opening of a new potential group (power busbar and AUX bus are interrupted to the
left)
– Infeed of the supply voltage L+ up to an infeed current of 10 A
● BaseUnits BU...B (recognizable by the dark-colored terminal box and the dark-colored
mounting rail release button):
– Conduction of the potential group (power busbar and AUX bus continued)
– Pick up of the supply voltage L+ for external components or loop-through with a
maximum total current of 10 A
● BaseUnits BU30-MSx (BaseUnit for the motor starter only)
Depending on the version, the BaseUnits in the "BU30-MSx" model series possess the
following properties:
– Opening a new potential group or continuing an existing one
– Feeding in the supply voltage L+ up to an infeed current of 7 A DC
– Opening a new load group or continuing an existing one by means of 500 V AC infeed
bus
– Feeding in the line voltage up to an infeed current of 32 A AC
Application planning
4.5 Forming potential groups
Distributed I/O system
System Manual, 02/2018, A5E03576849-AH 51
Placement and grouping of I/O modules
Each BaseUnit BU...D that you install in the ET 200SP configuration opens a new potential
group and supplies all subsequent I/O modules (on BaseUnits BU...B) with the necessary
supply voltage. The first 24 V DC I/O module to the right of the CPU/interface module must
be installed on a light-colored BaseUnit BU...D. Exception: If you insert an AC I/O module or
an AI Energy Meter as the first I/O module, the first BaseUnit in the ET 200SP configuration
can be a dark-colored BaseUnit. The requirement is that you use a CPU or IM 155-6 (as of
V3.0).
If you want to place another BaseUnit BU...B after a BaseUnit BU...D, disconnect the power
and AUX buses and open a new potential group at the same time. This allows individual
grouping of the supply voltages.
Note
All BaseUnits placed in a load group must match the infeed potential of the corresponding
light
-colored BaseUnits.
Do not connect any BaseUnit of the "BU...B" type on the right of a motor starter's BaseUnit
(BU30-MSxx).
Placing and connecting potential distributor modules
Potential distributor modules provide potential distributors integrated into the system that you
can use to configure a rapid, space-saving customized replacement for standard potential
distribution systems.
You can place potential distributor modules at any location within the ET 200SP distributed
I/O system. To do so, you must observe the same design rules as for placing and connecting
I/O modules. Potential distributor modules are only suitable for SELV/PELV.
A potential distributor module consists of a potential distributor BaseUnit (PotDis-BU) and (if
necessary) a potential distributor TerminalBlock (PotDis-TB) plugged onto it. If you do not
need the additional terminals of the PotDis-TB, install a BU cover (15 mm) on the
PotDis-BaseUnit.
You must not place a BaseUnit for I/O modules in a PotDis potential group formed with a
light-colored PotDis-BaseUnit.
Note
Identical voltages with potential distributor modules
You can only connect identical (supplied) voltages with to the terminals of a potential
distributor module or PotDis potential group. Example: You only connect 24
V DC.

Distributed I/O system
52 System Manual, 02/2018, A5E03576849-AH
Placement and grouping of I/O modules and motor starters
For the potential group (L+/M), the following slot rules apply within the motor starter modules
and other I/O modules of the ET 200SP:
● An unassembled BaseUnit (BaseUnit with BU cover) must be inserted between the CPU,
an interface module or an I/O module and the motor starter. This is not necessary
between the motor starters.
● The empty slot can take on the potential (24 V DC) of the potential group on the left of it
(L+, M), i.e. I/O modules and motor starters can be operated in the same potential group.
● If you would like to insert an I/O module on the right of a motor starter, then use only one
BaseUnit of the BU...D Typ A0 type (light terminal box).
● The BaseUnits BU30-MS2, BU30-MS4, BU30-MS5 and BU30-MS6 can take on the
potential groups of other BaseUnit types.
However, pay attention to the following exceptions:
– Only a BaseUnit of type BU30-MS1 or BU30-MS3 may follow an AS-i module
(AS-i potential group).
– Only BaseUnits with fail-safe motor starters can be connected together in the same
potential group of an F-PM-E.
WARNING
Hazardous Voltage
Can Cause Death, Serious Injury, or Property Damage.
Hazardous electrical voltage can cause electric shock, burns and property damage.
Disconnect your system and devices from the power supply before starting any assembly
tasks.

AUX bus (AUX(iliary) bus)
BaseUnits with additional AUX terminals (e.g. BU15-P16+
A10
+2D) enable the additional
connection of a potential (up to the maximum supply voltage of the module), which is applied
via the AUX bus.
In the case of light-colored BaseUnits, the AUX bus is interrupted to the left. In the case of
BaseUnits of motor starters, the AUX bus is interrupted to the left.
The AUX bus can be used individually:
● You can plug a maximum of 8 I/O modules into the corresponding potential group as a
PE bar.
● For additionally required voltage
NOTICE
AUX bus as PE bar
If you use an AUX bus as a protective conductor bar, attach the yellow-green color
identification labels to the AUX terminals, and establish a functional connection to the
central protective conductor connection.
If you stop using the AUX bus as a protective conductor bar, make sure you remove the
yellow-green color identification labels and remove the connection to the central protective
conductor connection again.
The AUX bus is designed as follows:
● Maximum current carrying capacity (at 60 °C ambient air temperature): 10 A
● Permissible voltage: Depending on the BaseUnit type (see BaseUnit manual
(http://support.automation.siemens.com/WW/view/en/59753521))
Self-assembling voltage buses
You must feed in the supply voltage L+ via the BaseUnit BU...D, BU30-MS1 or BU30-MS3 .
Each BaseUnit BU...B allows access to the supply voltage L+ via terminals (red/blue). The
motor starter BaseUnits "BU30-MS1", "BU30-MS2", "BU30-MS3", "BU30-MS4", "BU30-MS5"
and "BU30-MS6" do not have this access.

Forming potential groups with BaseUnit type B1
Introduction
The AC I/O modules of the ET 200SP are required to connect sensors/actuators with
alternating voltage 24 to 230 V AC.
Requirements
BaseUnits BU20-P12+A0+4B (BU type B1) and
● DI 4x120..230VAC ST digital input module
● DQ 4x24..230VAC/2A ST digital output module
Operating principle
Connect the required alternating voltage for the AC I/O modules directly at the BaseUnits
BU20-P12+A0+4B (terminals 1L, 2L/1N, 2N). Insert the AC I/O modules on the BaseUnits.
Note
Placing the BaseUnits for AC I/O modules
If you insert an AC I/O module as the first I/O module, a BaseUnit BU20
-P12+A0+4B can be
the first BaseUnit to the right of the CPU/interface module in the ET 200SP config
uration.
The requirement is that you use a CPU as of V3.0 or IM 155
-6 (as of V3.0).
•
The BaseUnits BU20-P12+A0+4B do not monitor the connected alternating voltage.
Please note the information on limiting the overvoltage and power rating in the AC I/O
module manuals.

Example of an ET 200SP configuration with fail-safe and non-fail-safe modules
In principle, it is not necessary to operate fail-safe and non-fail-safe modules in separate
potential groups. You can divide the modules into fail-safe and non-fail-safe potential groups
and install them.
The figure below shows an example of a configuration with fail-safe and non-fail-safe
modules within a single ET 200SP distributed I/O system.

Forming potential groups with motor starters
Properties of the 500 V AC infeed bus
The infeed bus has the following properties:
● The infeed bus is assembled by lining up the motor starter BaseUnits "BU30-MSx".
● The infeed bus distributes the energy to the SIMATIC ET 200SP motor starter within one
load group.
● You can open load groups by inserting a 500 V infeed BaseUnit (BU30-MS1, BU30-MS2
or BU30-MS5). With the BaseUnits BU30-MS3, BU30-MS4 or BU30-MS6, you can take
over the infeed bus from the left-hand BaseUnit.
● Via the infeed bus, you have the option of supplying three-phase load groups via L1, L2
and L3 or with single-phase load groups via L and N.
● The permissible voltage range is between 48 and 500 V AC.
● The maximum current carrying capacity is up 32 A (3-phase) at 50 °C and 500 V. Pay
attention to the derating values depending on the configuration.
Properties of the self-assembling voltage bus (L+)
Self-assembling voltage buses have the following properties:
● Maximum current: 7 A
● Rated voltage: 24 V
Pay attention to the derating values depending on the configuration.
The AUX1 bus is not supported in the BaseUnits of the SIMATIC ET 200SP motor starters.
WARNING
Electric shock when operating the infeed bus without touch protection cover
There is a risk of electric shock when touching the infeed bus if you have not fitted a touch
protection cover on the infeed bus on the right.
Always fit a touch protection cover on the infeed bus on the right (article number: 3RK1908-
1DA00-2BP0).
WARNING
Electric shock when operating a BaseUnit without an inserted motor starter
If you fit a BaseUnit for motor starters without cover (e.g. option handling), there is a risk of
an electric shock when touching the BaseUnit.
Always fit a cover on the BaseUnit (article number: 3RK1908-1CA00-0BP0).

5.1
Basics
Introduction
All modules of the ET 200SP distributed I/O system are open equipment. This means you
may only set up the distributed I/O system ET 200SP in enclosures, cabinets or electrical
equipment rooms and in a dry environment (IP20 degree of protection). The housings,
cabinets and electrical operating rooms must guarantee protection against electric shock and
spread of fire. The requirements regarding mechanical strength must also be observed. The
housings, cabinets, and electrical operating rooms must not be accessible without a key or
tool. Access must only be possible for personnel instructed or authorized to work with such
equipment.
Installation location
Install the ET 200SP distributed I/O system into a suitable housing/control cabinet with
sufficient mechanical strength, fire protection and at least IP54 degree of protection
according to EN 60529, and take into consideration the ambient conditions for operating the
devices.
Installation position
You can mount the ET 200SP distributed I/O system in any position. The preferred mounting
position is horizontal mounting on a vertical wall.
The ambient temperature may be restricted in certain installation positions. You will find
more information in the section Mechanical and climatic environmental conditions
(Page 296).
Pay attention to chapter "Installation conditions for motor starters (Page 68)" when using
motor starters.
Installation
5.1 Basics
Distributed I/O system
System Manual, 02/2018, A5E03576849-AH 65
Mounting rail
Mount the ET 200SP distributed I/O system on a mounting rail in accordance with EN 60715
(35 × 7.5 mm or 35 × 15 mm).
You need to ground the mounting rail separately in the control cabinet. Exception: If you
install the rail on grounded, zinc-plated mounting plates, there is no need to ground the rail
separately.
Note
If the ET
200SP distributed I/O system is exposed to vibration and shock loads, both ends of
the ET
200SP system assembly must be mechanically fixed to the mounting rail (e.g using
8WA1010
-1PH01 ground terminals). This measure prevents the ET 200SP distributed I/O
system from shifting to the side.
Note
If the ET
200SP distributed IO system is exposed to increased vibrations and shock, we
recommend that you screw the mounting rail to the mounting surface at intervals of approx.
200 mm.
The following are suitable surfaces for the mounting rails:
● Steel strip in accordance with Appendix A of EN 60715 or
● Tinned steel strip. We recommend these in conjunction with the mounting rails in the
section Accessories/spare parts (Page 302).
Note
If you use mounting
rails from other manufacturers, make sure that they have the
required properties for your ambient climatic conditions.

Installation
5.1 Basics
Distributed I/O system
System Manual, 02/2018, A5E03576849-AH 67
Observe the following rules:
● Installation starts on the left-hand side with the CPU/interface module.
● A light-colored BaseUnit BU..D0, BU30-MS1 or BU30-MS3 with infeed of the supply
voltage L+ follows the CPU/the interface module or is placed at the start of each potential
group.
If you fit an AC I/O module or an AI Energy Meter as the first I/O module, then the first
BaseUnit in the structure of the distributed I/O system ET 200SP may be a dark-colored
BaseUnit. The requirement is that you use a CPU or IM 155-6 (as of V3.0).
● This is followed by BaseUnits BU..B, BU30-MS2 or BU30-MS4 (with a dark-colored
terminal box).
● The matching I/O modules / motor starters can be plugged onto the BaseUnits. You will
find matching combinations of BaseUnits and I/O modules / motor starters in Application
planning (Page 36).
● The server module completes the configuration of the ET 200SP distributed I/O system.
Note
Mount the ET
200SP distributed I/O system only with disconnected supply voltage.

Installation conditions for motor starters
Observe the following installation conditions when using an ET 200SP motor starter:
● Installation position
You can fit the motor starter vertically or horizontally. The mounting position refers to the
alignment of the mounting rail The maximum permissible ambient temperature range
depends on the mounting position:
– Up to 60° C: Horizontal mounting position
– Up to 50° C: Vertical installation position
You also need to consider the current carrying capacity of the ET 200SP components.
In the case of a vertical mounting position, use end retainers "8WA1808" at both ends of
the ET 200SP station:
● Mounting rail
Use one of the following mounting rails:
– 35x15 mm DIN rail in accordance with DIN EN 60715
– 35x7.5 mm DIN rail in accordance with DIN EN 60715
– SIMATIC S7 mounting rail
● Current carrying capacity of the ET 200SP station
Current carrying capacity refers to the current load via the power bus and the infeed bus
of the ET 200SP station.
Depending on the ambient conditions and mounting position, you have to take account of the
fan unit or additional mechanical fixings.
Mechanical brackets
Use the mechanical brackets in the following situations:
● When using a 15 mm mounting rail
● With a vertical mounting position
● For applications according to shipbuilding standards in all mounting positions with 7.5 mm
and 15 mm mounting rails
Designing interference-free motor starters
For interference-free operation of the ET 200SP station in accordance with standard
IEC 60947-4-2, use a dummy module before the first motor starter. No dummy module is
required to the right of the motor starter.
Note the following mounting rules:

Rules and regulations for operation
Introduction
When installing the ET 200SP distributed I/O system as part of a plant or system, special
rules and regulations need to be adhered to depending on the area of application.
This section provides an overview of the most important rules that must be observed for the
integration of the ET 200SP distributed I/O system in a plant or system.
Specific application
Adhere to the safety and accident prevention regulations applying to specific applications,
for example machine protection guidelines.
EMERGENCY STOP devices
EMERGENCY STOP devices in accordance with IEC 60204 (corresponds to DIN VDE 0113)
must remain effective in all operating modes of the plant or system.
Excluding hazardous plant states
Hazardous operating states must not occur when
● the plant restarts after a voltage dip or power failure.
● Bus communication is reestablished following a fault.
If necessary, EMERGENCY STOP must be forced!

Line voltage
Below, everything you need to consider in terms of line voltage is described (refer to section
Insulation, protection class, degree of protection and rated voltage (Page 298)):
● For fixed plants or systems without an all-pole mains disconnection switch, a mains
disconnection device (all-pole) must be available in the building installation.
● For load power supplies, the configured rated voltage range must correspond to the local
line voltage.
● For all power circuits of the ET 200SP distributed I/O system, the fluctuation/deviation of
the line voltage from the rated value must be within the permitted tolerance.
24 V DC supply
Below you will find a description of what you need to pay attention to with 24 V DC supply:
● For buildings: In the event of danger through overload, you must provide lightning
protection measures for external lightning protection (e.g. lightning protection elements).
● For 24 V DC supply lines and signal lines: If there is a risk of overvoltages, you need to
take precautions to ensure internal lightning protection (e.g. lightning protection elements,
refer to section Accessories/spare parts (Page 302)).
● For 24 V DC supply: Make sure there is safe (electrical) isolation and separate cable
routing or increased insulation of the low voltage (SELV/PELV) to electric circuits with
dangerous potentials in accordance with IEC61131-2 / IEC 61010-2-201.
Requirements for power supplies in the event of voltage interruption
Note
To ensur
e adherence to IEC 61131-
2 and NAMUR Recommendation NE 21, only use power
packs/power supply units (230
V AC → 24 V DC) with a mains buffering time of at least
20
ms. Observe the relevant requirement in your product standards (e.g. 30
ms for "burners"
pursuant to EN 298) as regards possible voltage interruptions. The latest information on PS
components is availab
le on the Internet (https://mall.industry.siemens.com).
These requirements, of course, also apply to power packs/power supply units not
constructed using ET
200SP or S7-300-/400-/1500 technology.

Protection against outside electrical influences
Below is a description of what you must pay attention to in terms of protection against
electrical impacts and/or faults:
● Make sure that the system for discharging electromagnetic interference is connected to a
functional earth or to protective conductor with a sufficient cross-section for all plants with
an ET 200SP distributed I/O system.
● For supply, signal and bus lines, you must ensure that the laying of the lines and the
installation is correct.
● For signal and bus lines, you must ensure that a wire/cable break or a cross-circuit does
not lead to undefined states of the plant or system.

6.2
Additional rules and regulations for the operation of the ET 200SP
with fail-safe modules
6.2.1
Safety extra-low voltage (SELV, PELV) for failsafe modules and failsafe motor
starters
WARNING
The failsafe modules must be operated with safety extra-low voltage (SELV, PELV).
You can find more information on safety extra-low voltage (SELV, PELV) in the data sheets
of the applicable power supplies, for example.
The fail-safe modules operate with the 24 V DC rated voltage. The tolerance range is
19.2 V DC to 28.8 V DC.
The fail-safe motor starters operate with the 24 V DC rated voltage. The tolerance range is
20.4 V DC to 28.8 V DC.
Within the overvoltage range from 32 V DC to 36 V DC, the F-modules react in a fail-safe
manner and the inputs and outputs are passivated. For overvoltages greater than 36 V DC,
the F-modules are permanently de-energized.
Use a power supply unit that does not exceed Um = 36 V DC even in the event of a fault.
For more on this, refer to the information in the data sheet on overvoltage protection in the
case of an internal error. Or implement appropriate measures to limit the voltage, e.g. use
of an overvoltage protector.
All system components that can supply electrical energy in any form whatsoever must fulfill
this condition.
Each additional circuit (24 V DC) used in the system must have a safety extra-low voltage
(SELV, PELV). Refer to the relevant data sheets or contact the manufacturer.
Sensors and actuators with an external power supply can also be connected to F-modules.
Make sure that power is supplied to these components from safety extra-low voltage
(SELV, PELV) as well. The process signal of a 24 V DC digital module may not exceed a
fault voltage Um in the event of a fault.
WARNING
Even when a fault occurs, the permissible potential difference between the supply of the
interface module (bus voltage) and the load voltage must not be exceeded.
An external direct electrical connection is one way to meet this requirement. This also
prevents potential differences from causing voltage additions at the individual voltage
sources, which would cause the fault voltage Um to be exceeded.

6.2.2
Requirements for sensors and actuators for fail-safe modules and fail-safe
motor starters
General requirements for sensors and actuators
Note the following important warning regarding safety-related use of sensors and actuators:
WARNING
Note that instrumentation with sensors and actuators bears a considerable
safety
responsibility
. Also bear in mind that sensors and actuators generally do not have proof-
test
intervals of 20 years as defined in IEC 61508:2010 without considerable loss of safety.
The probability of hazardous faults and the rate of hazardous faults of safety functions must
comply with an SIL-defined high limit. A listing of values achieved by F-modules in the
technical specifications of the F-modules is available under "Fail-safe performance
characteristics".
To achieve the required safety class, suitably qualified sensors and actuators are
necessary.
Additional sensor requirements
General rule: To achieve SIL3/Cat. 3/PLe, a single-channel sensor is adequate. However, to
achieve SIL3/Cat. 3/PLe with a single-channel sensor, the sensor itself must be
SIL3/Cat. 3/PLe-capable; otherwise the sensor must be connected by two channels to
achieve this safety level.
To achieve SIL3/Cat. 4/PLe, sensors must be connected by two channels.
WARNING
In the case of fail-safe input modules, the value "0" is output to the F-CPU after detection of
faults. You therefore need to make sure that the sensors are implemented in such a way as
to ensure the reliable reaction of the safety program when the sensor is in the "0" state.
Example: In its safety program, an EMERGENCY-STOP sensor must achieve the
shutdown of the relevant actuator when it is in the "0" state (EMERGENCY-STOP button
pressed).
Additional requirements for sensors for fail-safe motor starters
Only single-channel sensors that fulfill the required safety category themselves may be
connected to the fail-safe motor starter's F-DI. Fail-safe laying must be observed in
accordance with the required safety category.

6.2 Additional rules and regulations for the operation of the ET 200SP with fail-safe modules
Distributed I/O system
92 System Manual, 02/2018, A5E03576849-AH
Duration requirements for sensor signals
WARNING
Observe the following requirements for sensor signals:
• To ensure the correct detection of the sensor signals via fail-safe modules with inputs,
you need to make sure that the sensor signals are output for a minimum duration.
• For pulses to be detected with certainty, the time between two signal changes (pulse
duration) must be greater than the PROFIsafe monitoring time.
Reliable detection by F-modules with inputs
The minimum duration of sensor signals for F-modules with inputs depends on the
configured input delay, the parameters of the short circuit test of the sensor supplies, and the
configured discrepancy behavior for 1oo2 evaluation. The signal must be greater than the
maximum response time of the configured application. Information on calculating the
maximum response time can be found in the section "Response times" of the relevant F-
module.
The maximum permitted switching frequency of the sensor signals results from the minimum
duration.
Additional requirements for actuators
The fail-safe output modules test the outputs at regular intervals. The F-module briefly
switches off the activated outputs and, if necessary, switches on the deactivated outputs.
You can assign the maximum duration of the test pulses (dark and light period) with
parameters.
Fast reacting actuators may briefly drop out or be activated during the test. If your process
does not tolerate this, set the pulse duration of the light or dark test correspondingly or use
actuators that have sufficient lag.
WARNING
If the actuators switch voltages higher than 24 V DC (e.g. 230 V DC), safe galvanic
isolation must be ensured between the outputs of a fail-safe output module and the parts
carrying a higher voltage (in compliance with the IEC 60664-1 standard).
This is generally the case for relays and contactors. Particular attention must be paid to this
with semiconductor switching devices.
Technical specifications of sensors and actuators
Refer to the manuals of the fail-safe modules for technical specifications to assist you in
selecting sensors and actuators.
Wiring
6.3 Additional rules and instructions for operation with motor starters
Distributed I/O system
System Manual, 02/2018, A5E03576849-AH 93
6.2.3
Crosstalk of digital input/output signals
When fail-safe digital output and input signals are in a single cable, F-DQ modules and
F-PM-E modules may experience readback errors.
Cause: capacitive crosstalk
During the bit pattern test of the outputs or the sensor supply of the inputs, the steep
switching edge of the output drivers caused by the coupling capacitance of the line may
result in crosstalk to other non-activated output or input channels. This may then lead to a
response of the readback circuit in these channels. A cross circuit/short-circuit is detected,
which leads to safety-related tripping.
Remedy:
● Separate cables for F-DI modules, F-DQ modules, and F-PM-E modules or non-fail-safe
DQ modules
● Separate cables for F-DQ channel and F-DI channels for the F-PM-E module
● Coupling relay or diodes in the outputs
● Disable the sensor supply test if safety class requirements allow it.
Cause: magnetic crosstalk
Note that an inductive load connected to the F-DQ channels can induce coupling of a strong
magnetic field.
Remedy:
● Separate the inductive loads spatially or shield against the magnetic field.
● Configure the readback time to 50 ms or higher.

6.4
Operating the ET 200SP on grounded incoming supply
Introduction
Below you will find information on the overall configuration of an ET 200SP distributed I/O
system on a grounded incoming supply (e.g. TN-S network). The specific subjects discussed
are:
● Disconnecting devices and short-circuit and overload protection according to IEC 60364
(corresponds to DIN VDE 0100) and IEC 60204 (corresponds to DIN VDE 0113)
● Load power supplies and load circuits.
Grounded incoming supply
In the case of grounded incoming supplies (TN-S system) the neutral conductor (N) and the
protective conductor (PE) are each grounded. Both conductors form a part of the overvoltage
concept. When a plant is in operation, the current flows across the neutral conductor. When
a fault occurs, for example, a single ground fault between a live conductor and ground, the
current flows through the protective conductor.
Safe electrical isolation (SELV/PELV in accordance with IEC 61131-2 or 61010-2-201)
Load current / power supply modules with safe electrical isolation are required for the
operation of the ET 200SP distributed I/O system. In accordance with IEC 61131-2 / 61010-
2-201, this protection is referred to as SELV (Safety Extra Low Voltage)/PELV (Protective
Extra Low Voltage).
The wiring of SELV/PELV circuits must either be isolated from the wiring of other circuits that
are not SELV/PELV or the insulation of all conductors must be dimensioned for the higher
voltage.
Configuration of ET 200SP with ungrounded reference potential
To conduct interference currents, the reference potential of the CPU/interface module and
the BaseUnits BU15...D is connected internally via an RC combination (IM/CPU:
R = 10 MΩ / C = 100 nF, BU15...D: R = 10 MΩ / C = 4 nF) with the mounting rail (functional
grounding).
● This configuration conducts high-frequency interference currents and prevents static
charges.
● It is always possible to configure an ungrounded setup of the ET 200SP distributed I/O
system as the ET 200SP distributed I/O system has no fixed ground connection. The
power pack/power supply module for 24 V DC must also be ungrounded and electrically
isolated.
If you want to configure the ET 200SP distributed I/O system with grounded reference
potential, connect the 1M connection of the CPU/interface module electrically with the
protective conductor.

Color identification labels
The color identification labels are module-specific labels for color coding the potentials of the
I/O modules. A color code (e.g. 01) is printed on each color identification label and I/O
module. The color code allows you to read which color identification label is required for the
terminals of the associated BaseUnit directly from the I/O module.
The following versions of color coded labels are available:
● Module-specific color combinations for the process terminals (see the device manuals I/O
modules (http://support.automation.siemens.com/WW/view/en/55679691/133300)).
The different colors have the following meaning: Gray = input or output signal, red =
potential +, blue = ground.
● For the AUX terminals in the colors yellow-green, blue or red
● For the add-on terminals in the colors blue-red
● For the potential distributor modules (see manual BaseUnits
(http://support.automation.siemens.com/WW/view/en/59753521)):
– For PotDis-BaseUnit PotDis-BU-P1/x-R: red
For PotDis-BaseUnit PotDis-BU-P2/x-B: blue
– For PotDis-TB-P1-R: red or gray
For PotDis-TB-P2-B: blue or gray
For PotDis-TB-BR-W: depending on application, yellow/green, blue, red or gray
For PotDis-TB-n.c.-G: gray
Reference identification labels
The reference identification labels (in accordance with EN 81346) can be inserted onto each
CPU/interface module, BusAdapter, BaseUnit, I/O module and PotDis-TerminalBlock. This
makes it possible to create a fixed assignment between the reference identification label of

Configuring ET 200SP
Introduction
The ET 200SP distributed I/O system is configured and assigned parameters with STEP 7
(CPU/interface module, I/O modules, motor starter and server module) or using configuration
software of a third-party manufacturer (interface module, I/O modules, motor starter and
server module).
"
Configuring
" is understood to mean the arranging, setup and networking of devices and
modules within the device view or network view. STEP 7 graphically represents modules and
racks. Just like "real" module racks, the device view allows the insertion of a defined number
of modules.
When the modules are inserted, STEP 7 automatically assigns the addresses and a unique
hardware identifier (HW identifier). You can change the addresses later. The hardware
identifiers cannot be changed.
When the automation system is started, the CPU/interface module compares the configured
planned configuration with the system's actual configuration. You can make parameter
settings to control the response of the CPU/interface module to errors in the hardware
configuration.
"
Parameterizing
" the components used signifies setting their properties. During parameter
assignment, the hardware parameters are set and the settings for data exchange are made:
● Properties of the modules to which parameters can be assigned
● Settings for data exchange between components
STEP 7 compiles the hardware configuration (result of "configuring" and "assigning
parameters") and downloads it to the CPU/interface module. The CPU/interface module then
connects to the configured components and transfers their configuration and parameters.
Modules can be replaced very easily because STEP 7 transfers the configuration and
parameters when a new module is inserted.

Reading out the configuration
Introduction
When a connection exists to a physically present CPU, you can load the configuration of this
CPU (including centrally present modules) from the device into your project using the
"Hardware detection" function. You do not need to manually configure the CPU and the
centrally present modules, as the physical configuration is read out automatically.
If you have already configured a CPU and the centrally present modules and you want to
load the current configuration and parameters in a new project, it is advisable to use the
"Upload device as new station" function. For additional information about this function, refer
to section Backing up and restoring the CPU configuration (Page 231).

parameter assignment subsequently.
Note
If you want to go online after the hardware detection, you have to first download the detected
configuration to the CPU; otherwise, an error
may occur due to inconsistent configurations.
Properties of central modules
The properties of the CPUs have special significance for system behavior. You can set the
following for a CPU using STEP 7:
● Startup behavior
● Parameter assignment of the interface(s), for example, IP address, subnet mask
● Web server, e.g. activation, user administration, and languages
● OPC UA server
● Global Security Certificate Manager
● Cycle times, e.g. maximum cycle time
● System and clock memory
● Protection level for access protection with assigned password parameter
● Time and day settings (daylight saving/standard)
The properties that can be set and the corresponding value ranges are specified by STEP 7.
Fields that cannot be edited are grayed out.

Addressing
Introduction
In order to address the automation components or I/O modules, they have to have unique
addresses. The following section explains the various address areas.
Configuring
7.2 Configuring the CPU
Distributed I/O system
140 System Manual, 02/2018, A5E03576849-AH
I/O address
I/O addresses (input/output addresses) are required in the user program to read inputs and
set outputs.
STEP 7 automatically assigns input and output addresses when you connect the modules.
Each module uses a continuous area in the input and/or output addresses corresponding to
its volume of input and output data.
Figure 7-5 Example with input / output addresses from STEP 7
STEP 7 assigns the address areas of the modules by default to the process image partition 0
("Automatic updating"). This process image partition is updated in the main cycle of the CPU.
Device address (e.g. Ethernet address)
Device addresses are addresses of programmable modules with interfaces to a subnet (e.g.,
IP address or PROFIBUS address). They are required to address the various devices on a
subnet, for example, to download a user program.

submodules. You use the hardware identifier in the case of diagnostic messages or
operations, for example, to identify a defective module or the module addressed.

7.2.3
Process images and process image partitions
7.2.3.1
Process image - overview
Process image of the inputs and outputs
The process image is a memory area of the CPU and includes an image of the signal states
of the input/output modules. At the start of the cyclic program, the CPU transfers the signal
states of the input modules to the process image of the inputs. At the end of the cyclic
program, the CPU transfers the process image of the outputs as a signal state to the output
modules. You access this process image memory area in the user program by addressing
the operand areas inputs (I) and outputs (O).
Advantages of the process image
A process image offers the advantage that you can access a consistent image of the
process signals during cyclic program execution. If a signal state at an input module changes
during program processing, the signal state is retained in the process image. The CPU does
not update the process image until the next cycle.
You can only assign the addresses of a module to a single process image partition.
32 process image partitions
By means of process image partitions, the CPU synchronizes the updated inputs/outputs of
particular modules with defined user program sections.
The overall process image is subdivided into up to 32 process image partitions (PIP).
The CPU updates PIP 0 in each program cycle (automatic update) and assigns it to OB 1.
You can assign the process image partitions PIP 1 to PIP 31 to the other OBs during
configuration of the input/output modules in STEP 7.
After the OB has been started, the CPU updates the assigned process image partition for
inputs and reads in the process signals. At the end of the OB the CPU writes the outputs of
the assigned process image partition directly to the peripheral outputs without having to wait
for the completion of the cyclic program processing.
7.2.3.2
Automatically updating process image partitions
You can assign one process image partition to each organization block. In this case, the user
program automatically updates the process image partition. The exceptions are PIP 0 and
isochronous OBs.

7.2 Configuring the CPU
Distributed I/O system
System Manual, 02/2018, A5E03576849-AH 143
Updating the process image partition
The process image partition is divided into two parts:
● Process image partition of the inputs (PIPI)
● Process image partition of the outputs (PIPQ)
The CPU always updates/reads the process image partition of the inputs (PIPI) before
processing of the associated OB. The CPU outputs the process image of the outputs (PIPQ)
at the end of the OB.
The figure below illustrates the updating of the process image partitions.
Figure 7-8 Updating process image partitions
7.2.3.3
Update process image partitions in the user program
Requirements
As an alternative to the automatic updating of process image partitions, you can update
process images with the "UPDAT_PI" instruction or the "UPDAT_PO" instruction. In STEP 7,
these instructions are available on the "Instructions" task card under "Extended instructions".
They can be called from any point in the program.
Requirements for updating process image partitions with the "UPDAT_PI" and "UPDAT_PO"
instructions:
● The process image partitions are not allowed to be assigned to any OB, which means
they are not allowed to be automatically updated.
Note
Update of PPI 0
PIP 0 (automatic update) cannot be updated with the "UPDAT_PI" and "UPDAT_PO"
instructions.
UPDAT_PI: updates the process image partition of the inputs
With this instruction you read the signal states from the input modules into the process
image partition of the inputs (PIPI).
UPDAT_PO: updates the process image partition of the outputs
With this instruction you transfer the process image partition of the outputs to the output
modules.

7.2 Configuring the CPU
Distributed I/O system
144 System Manual, 02/2018, A5E03576849-AH
Synchronous cycle interrupt OB
In the synchronous cycle interrupt OBs, you use the "SYNC_PI" and "SYNC_PO" operations
to update the process image partitions of the operations. For additional information on the
synchronous cycle interrupt OBs, refer to the STEP 7 Online Help.
Direct I/O access to the inputs and outputs of the module
You also have direct read and write access to the I/O, as an alternative to access via the
process image, should direct access be required for programming reasons. This prevents a
subsequent output of the process image from again overwriting the value written by direct
access.

The F-destination address is saved permanently on the coding element of the ET 200SP
fail-safe modules. Fail-safe motor starters do not need an F-destination address or a coding

Note
The supply voltage
L+ must be applied to the F-module when the F-destination address is
assigned.
Note
Note the following in conjunction with configuration control:
Before you can use configuration control
together with F-modules, you must assign the

Response to triggers
The occurrence of a start event results in the following reaction:
● If the event comes from an event source to which you have assigned an OB, this event
triggers the execution of the assigned OB. The event enters the queue according to its
priority.
● If the event comes from an event source to which you have not assigned an OB, the CPU
executes the default system reaction.

manual.
Assignment between event source and OBs
The type of OB determines where you make the assignment between OB and event source:
● With hardware interrupts and isochronous mode interrupts, the assignment is made
during the configuration of the hardware or when the OB is created.
● In the case of the MC-Servo, MC-PreServo, MC-PostServo and MC-Interpolator, STEP 7
automatically assigns the OBs 91/92 as soon as you add a technology object.
● For all other types of OB, the assignment is made when the OB is created, where
applicable after you have configured the event source.
For hardware interrupts, you can change an assignment which has already been made
during runtime with the instructions ATTACH and DETACH. In this case, only the actually
effective assignment changes, and not the configured assignment. The configured
assignment takes effect after loading, and at startup.
The CPU ignores hardware interrupts to which you did not assign an OB in your
configuration or which occur after the DETACH instruction. The CPU does not check
whether an OB is assigned to this event when an event arrives, but only prior to the actual
processing of the hardware interrupt.
Basics of program execution
8.1 Events and OBs
Distributed I/O system
148 System Manual, 02/2018, A5E03576849-AH
OB priority and runtime behavior
If you have assigned an OB to the event, the OB has the priority of the event. The CPU
supports the priority classes 1 (lowest priority) to 26 (highest priority). The following items are
essential to the processing of an event:
● Calling and processing of the assigned OB
● The update of the process image partition of the assigned OB
The user program processes the OBs exclusively on a priority basis. This means the
program processes the OB with the highest priority first when multiple OB requests occur at
the same time. If an event occurs that has a higher priority than the currently active OB, this
OB is interrupted. The user program processes events of the same priority in order of
occurrence.
Note
Communication
Communication (e.g. test functions with the PG) always works permanently with the priority
15.
So as not to unnecessarily prolong program runtime in the case of time-critical
applications, these OBs should not be interrupted by communication. Assign a priority >15
for these OBs.

Basics of program execution
8.2 CPU overload behavior
Distributed I/O system
System Manual, 02/2018, A5E03576849-AH 149
8.2
CPU overload behavior
Requirement
For the event scenarios considered in the following section, we assume that you have
assigned an OB to each event source and that these OBs have the same priority. The
second condition, in particular, is only for the sake of a simplified representation.
Principle of CPU overload behavior
An occurring event triggers the execution of the associated OB. Depending on the OB
priority and the current processor load, a time delay may occur before the OB is executed
when there is an overload. The same event can therefore occur once or several times before
the user program processes the OB belonging to the preceding event. The CPU treats such
a situation as follows: The operating system positions the events in the order of their
occurrence into the queue for their priority level.
To cope with temporary overload situations, you can limit the number of pending events
originating from one and the same source. The next event is discarded as soon as the
maximum number of pending start events of a specific cyclic interrupt OB, for example, is
reached.
An overload occurs when events which originate from the same source occur faster than
they can be processed by the CPU.
More detailed information is available in the following sections.
Discarding similar events or handling them later
Below, the term "similar events" refers to events from a single source, such as triggers for a
specific cyclic interrupt OB.
The OB parameter "Events to be queued" is used to specify how many similar events the
operating system places in the associated queue and therefore post-processes. If this
parameter has the value 1, for example, exactly one event is stored temporarily.
Note
The post
-processing of cyclic events is often undesirable, as this can lead to an overload
with OBs of the same or lower priority. Therefore, it is generally advantageous to discard
similar events and to react to the overload situation during the n
ext scheduled OB
processing. If the value of the "Events to be queued" parameter is low, this ensures that an
overload situation is defused rather than aggravated.
Basics of program execution
8.2 CPU overload behavior
Distributed I/O system
150 System Manual, 02/2018, A5E03576849-AH
If the maximum number of start events is reached in the queue for a cyclic interrupt OB
(Cyclic interrupt), for example, each additional start event is only counted and subsequently
discarded. During the next scheduled execution of the OB, the CPU provides the number of
discarded start events in the "Event_Count" input parameter (in the start information). You
can then react appropriately to the overload situation. The CPU then sets the counter for lost
events to zero.
If the CPU discards a start event for a cyclic interrupt OB the first time, its further behavior
depends on the OB parameter "Report event overflow into diagnostics buffer": If the check
box is selected, the CPU enters the event DW#16#0002:3507 once in the diagnostics buffer
for the overload situation at this event source. The CPU suppresses additional diagnostics
buffer entries of the event DW#16#0002:3507 that refer to this event source until all events
from this source have been post-processed.
Threshold mechanism for time error OB request
The cyclic interrupt OB parameter "Enable time error" is used to specify whether the time
error interrupt should be called when a specific overload level is reached for similar events.
You can find the OB parameter "Enable time error" in the properties of the OB in the
"Attributes" category.
If you enable the time error OB (option box set), you define, with the "Event threshold for
time error" OB parameter, the number of similar events in the queue that cause the user
program to call the time error OB. If this parameter has the value 1, for example, the CPU
enters the event DW#16#0002:3502 once in the diagnostics buffer and requests the time
error OB when the second event occurs. The CPU suppresses additional diagnostics buffer
entries of the event DW#16#0002:3502 until all events from this source have been post-
processed.
In the event of an overload, you therefore have the option of programming a reaction well
before the limit is reached for similar events and thus before the events are discarded.
The following value range applies to the "Event threshold for time error" parameter: 1 ≤
"Event threshold for time error" ≤ "Events to be queued".

8.3
Asynchronous instructions
Difference between synchronous/asynchronous instructions
In program processing, a differentiation is made between synchronous and asynchronous
instructions.
The "synchronous" and "asynchronous" properties relate to the temporal relationship
between the call and execution of the instruction.
The following applies to synchronous instructions: When the call of a synchronous instruction
is ended, the execution is also ended.
This is different in the case of asynchronous instructions: When the call of an asynchronous
instruction is ended, the execution of the asynchronous instruction is not necessarily ended
yet. This means the execution of an asynchronous instruction can extend over multiple calls.
The CPU processes asynchronous instructions in parallel with the cyclic user program.
Asynchronous instructions generate jobs in the CPU for their processing.
Asynchronous instructions are usually instructions for transferring data (data records for
modules, communication data, diagnostics data).

Processing of asynchronous instructions
The figure below shows the difference between processing an asynchronous instruction and
processing a synchronous instruction. In this figure the asynchronous instruction is called
five times before the execution is completed, for example, a data record is completely
transferred.
①
First call of the asynchronous instruction, start of processing
②
Intermediate call of asynchronous instruction, continuation of processing
③
Last call of the asynchronous instruction, termination of processing
④
The synchronous instruction is completely processed at each call

Parallel processing of asynchronous instruction jobs
A CPU can process several asynchronous instruction jobs in parallel. The CPU processes
the jobs in parallel under the following conditions:
● Several asynchronous instruction jobs are called at the same time.
● The maximum number of concurrently running jobs for the instruction is not exceeded.
The figure below shows the parallel processing of two jobs of the instruction WRREC. The
two instructions are processed in parallel for a specific period here.
Figure 8-2 Parallel processing of the asynchronous instruction WRREC
Assignment of call to job of the instruction
To execute an instruction over multiple calls, the CPU must be able to uniquely assign a
subsequent call to a running job of the instruction.
To assign a call to a job, the CPU uses one of the following two mechanisms, depending on
the type of the instruction:
● Via the instance data block of the instruction (in the case of the "SFB" type)
● The input parameters of the instruction identifying the job. These input parameters must
match in each call during processing of the asynchronous instruction.
Example: A "Create_DB" instruction job is identified by the input parameters LOW_LIMIT,
UP_LIMIT, COUNT, ATTRIB and SRCBLK.
The following table shows which instruction you can identify with which input parameters.

Status of an asynchronous instruction
An asynchronous instruction shows its status via the block parameters STATUS/RET_VAL
and BUSY. Many asynchronous instructions also use the block parameters DONE and
ERROR.
The figure below shows the two asynchronous instructions WRREC and CREATE_DB.
①
The input parameter REQ starts the job to execute the asynchronous instruction.
②
The output parameter DONE indicates that the job was completed without error.
③
The output parameter BUSY indicates whether the job is currently being processed. When
BUSY =1, a resource is assigned for the asynchronous instruction. If BUSY = 0, then the re-
source is free.
④
The output parameter ERROR indicates that an error has occurred.
⑤
The output parameter STATUS/RET_VAL provides information on the status of the job execu-
tion. The output parameter STATUS/RET_VAL receives the error information after the occur-
rence of an error.
Figure 8-3 Block parameters of asynchronous instructions using the instructions WRREC and
CREATE_DB as examples.
Summary
The table below provides you with an overview of the relationships described above. It
shows in particular the possible values of the output parameters if processing is not
completed after a call.
Note
Following every call, you must evaluate the relevant output parameters in your program.

Consumption of resources
Asynchronous instructions occupy resources in the CPU while they are being processed.
The resources are limited depending on the type of CPU and instruction; the CPU can only
process a maximum number of asynchronous instruction jobs simultaneously. The resources
are available again after a job has been successfully completed or processed with an error.
Example: For the RDREC instruction, a 1512SP-1 PN CPU can process up to 20 jobs in
parallel.
If the maximum number of simultaneous jobs for an instruction is exceeded, the instruction
returns the error code 80C3 (lack of resources) in the block parameter STATUS. The
execution of the job is stopped until a resource becomes free again.
Note
Lower-level asynchronous instructions
Several asynchronous instructions use one or more lower
-level asynchronous instructions
for their processing. This dependence is shown in the tables below.
Please note that, if there are several l
ower-level instructions, typically only one lower-level
instruction is occupied at one time.

9.1
Overview of the protective functions of the CPU
Introduction
This chapter describes the following functions for protecting the ET 200SP against
unauthorized access:
● Access protection
● Know-how protection
● Copy protection
Further measures for protecting the CPU
The following measures additionally increase the protection against unauthorized access to
functions and data of the CPU from external sources and via the network:
● Deactivation of the Web server
● Deactivation of the OPC UA server (you will find further information on the security
mechanisms for OPC UA servers in the Communication
(https://support.industry.siemens.com/cs/ww/en/view/59192925) function manual)
● Deactivation of time synchronization via an NTP server
● Deactivation of PUT/GET communication
When using the Web server, you protect your ET 200SP distributed I/O system against
unauthorized access
● By setting password-protected access rights for certain users in user management.
● By using the default "Allow access via HTTPS only" option.
This option allows access to the Web server with the secure Hypertext transfer protocol
HTTPS only.

Configuring access protection for the CPU
Introduction
The CPU offers four access levels to limit access to specific functions.
By setting up the access levels and the passwords for a CPU, you limit the functions and
memory areas that are accessible without entering a password. You specify the individual
access levels as well as the entry of their associated passwords in the object properties of
the CPU.
Access levels of the CPU
Table 9- 1 Access levels and access restrictions
Access levels
Access restrictions
Full access (no
protection)
Any user can read and change the hardware configuration and the blocks.
Read access With this access level, read-only access to the hardware configuration and the
blocks is possible without entering a password, which means you can download
the hardware configuration and blocks to the programming device. In addition, HMI
access and access to diagnostics data is possible.
Without entering the password, you cannot load any blocks or hardware configura-
tion into the CPU. Additionally, the following are
not
possible without the pass-
word:
• Writing test functions
• Firmware update (online)
HMI access With this access level only HMI access and access to diagnostics data are possi-
ble without entering the password.
Without entering the password, you can neither load blocks nor the hardware
configuration into the CPU, nor load blocks and hardware configuration from the
CPU into the programming device. Additionally, the following are
not
possible
without the password:
• Writing test functions
• Changing the mode (RUN/STOP)
• Firmware update (online)
• Display of the online/offline comparison status
No access
(complete pro-
tection)
When the CPU has complete protection, no read or write access to the hardware
configuration and the blocks is possible (without access authorization in the form
of a password). HMI access is also not possible. The server function for PUT/GET
communication is disabled in this access level (cannot be changed).
Authentication with the password will again provide you full access to the CPU.
You can find a list of which functions are possible in the various protection levels in the
STEP 7 online help under the entry "Setting options for the protection".
Protection
9.2 Configuring access protection for the CPU
Distributed I/O system
System Manual, 02/2018, A5E03576849-AH 163
Properties of the access levels
Each access level allows unrestricted access to certain functions without entering a
password, for example, identification using the "Accessible devices" function.
The CPU's default setting is "No restriction" and "No password protection". In order to protect
access to a CPU, you need to edit the properties of the CPU and set up a password. In the
default access level "Full access (no protection)" every user can read and change the
hardware configuration and the blocks. A password is not set and is also not required for
online access.
Communication between the CPUs (via the communication functions in the blocks) is not
restricted by the access level of the CPU, unless PUT/GET communication is deactivated in
the "No access" (complete protection) access level.
Entry of the right password allows access to all the functions that are allowed in the
corresponding level.
Note
Configuring an access level does not replace know-how protection
Configuring access levels offers a high degree of protection against unauthorized changes to
the CPU by restricting the rights to downloa
d the hardware and software configuration to the
CPU. However, blocks on the SIMATIC memory card are not write
- or read-protected. Use
know
-how protection to protect the code of blocks on the SIMATIC memory card.
Behavior of functions with different access levels
The STEP 7 online help includes a table which lists the online functions that are available in
the different access levels.
Protection
9.2 Configuring access protection for the CPU
Distributed I/O system
164 System Manual, 02/2018, A5E03576849-AH
Selecting the access levels
To configure the access levels of a CPU, follow these steps:
1. Open the properties of the CPU in the Inspector window.
2. Open the "Protection" entry in the area navigation.
A table with the possible access levels is available in the Inspector window.
Figure 9-1 Possible access levels
3. Activate the desired protection level in the first column of the table. The green check
marks in the columns to the right of the access level show you which operations are still
available without entering the password. In the example (see above), read access and
HMI access are still possible without a password.
4. In the "Enter password" column, specify a password for the access level "Full access" in
the first row. In the "Confirm password" column, enter the selected password again to
guard against incorrect entries.
Ensure that the password is sufficiently secure, i.e. does not follow a pattern that can be
recognized by a machine.
5. Assign additional passwords as needed to other access levels if the selected access level
allows you to do so.
6. Download the hardware configuration for the access level to take effect.
The CPU logs the entry of the correct or incorrect password and any changes in the
configuration of the access levels by a corresponding entry in the diagnostics buffer.
Protection
9.3 Using the user program to set additional access protection
Distributed I/O system
System Manual, 02/2018, A5E03576849-AH 165
Behavior of a password-protected CPU during operation
The CPU protection takes effect after you have downloaded the settings to the CPU.
Before an online function is executed, the CPU checks the necessary permission and, if
necessary, prompts the user to enter a password. You can only execute password-protected
functions from one programming device/PC at any time. Another programming device/PC
cannot log on.
Access authorization to the protected data is in effect for the duration of the online
connection or until you rescind the access authorization manually with "Online > Delete
access rights".
Access levels for F-CPUs
For the fail-safe CPUs, there is an additional access level in addition to the four described
access levels. For additional information on this access level, refer to the description of the
fail-safe system SIMATIC Safety Programming and Operating Manual SIMATIC Safety -
Configuring and Programming
(http://support.automation.siemens.com/WW/view/en/54110126).

operation. You can find a description of this block in the online help under the keyword
"ENDIS_PW: Limit and enable password legitimation".
Protection
9.4 Know-how protection
Distributed I/O system
166 System Manual, 02/2018, A5E03576849-AH
9.4
Know-how protection
Application
You can use know-how protection to protect one or more OB, FB or FC blocks as well as
global data blocks in your program from unauthorized access. Enter a password to restrict
access to a block. The password offers high-level protection against unauthorized reading or
manipulation of the block.
Password provider
As an alternative to manual entry of password, you can connect a password provider to
STEP 7. When using a password provider, you select a password from a list of available
passwords. When a protected block is opened, STEP 7 connects to the password provider
and retrieves the corresponding password.
To connect a password provider you have to install and activate it. A settings file in which
you define the use of a password provider is also required.
A password provider offers the following advantages:
● The password provider defines and manages the passwords. When know-how protected
blocks are opened, you work with symbolic names for passwords. A password is marked,
for example, with the symbolic name "Machine_1" n the password provider. The actual
password behind "Machine1" remains hidden from you.
A password provider therefore offers you optimum block protection as the users do not
know the password themselves.
● STEP 7 automatically opens know-how protected blocks without the direct entry of a
password. This saves you time.
You will find more information on connecting a password provider in the STEP 7 online help.
Readable data
If a block is know-how protected, only the following data is readable without the correct
password:
● Block title, comments and block properties
● Block parameters (INPUT, OUTPUT, IN, OUT, RETURN)
● Call structure of the program
● Global tags without information on the point of use

Further actions
Further actions that can be carried out with a know-how protected block:
● Copying and deleting
● Calling in a program
● Online/offline comparison
● Load
Global data blocks and array data blocks
You can provide global data blocks (global DBs) with know-how protection. Users who do
not possess the valid password can read the global data block but not change it.
You cannot provide array data blocks (array DBs) with know-how protection.
Setting up block know-how protection
To set up block know-how protection, follow these steps:
1. Open the properties of the block in question.
2. Select the "Protection" option under "General".

6. Click "OK" to confirm your entry.
7. Close the "Know-how protection" dialog by clicking "OK".
Result: The selected blocks are now know-how protected. Know-how protected blocks are
marked with a lock in the project tree. The password entered applies to all blocks selected.
Note
Password provider
Alternatively, you can set up know
-how protection for blocks with a password provider.
Opening know-how protected blocks
To open a know-how protected block, follow these steps:
1. Double-click the block to open the "Access protection" dialog.
2. Enter the password for the know-how protected block.
3. Click "OK" to confirm your entry.
Result: The know-how-protected block is open.
Once you have opened the block, you can edit the program code and the block interface of
the block for as long as the block or STEP 7 is open. You must enter the password again the
next time you open the block. If you close the "Access protection" dialog with "Cancel", you
will be able to open the block but you cannot display the block code or edit the block.
If you copy the block or add it to a library, for example, this does not cancel the know-how
protection of the block. The copies will also be know-how-protected.

9.5 Copy protection
Distributed I/O system
170 System Manual, 02/2018, A5E03576849-AH
9.5
Copy protection
Application
The copy protection allows you to protect your program against unauthorized duplication.
With copy protection you associate the blocks with a specific SIMATIC memory card or CPU.
Through the linking of the serial number of a SIMATIC memory card or of a CPU the use of
this program or of this block is only possible in conjunction with a specific SIMATIC memory
card or CPU.
Copy and know-how protection
Recommendation: to prevent unauthorized reset of copy protection, additionally apply
know-how protection to a copy-protected block. To do this, first set up copy protection and
then apply know-how protection for the block.
Setting up copy protection
To set up copy protection, follow these steps:
1. Open the properties of the block in question.
2. Select the "Protection" option under "General".
Figure 9-7 Setting up copy protection (1)
3. In the "Copy protection" area, select either the "Bind to serial number of the CPU" entry or
the "Bind to serial number of the memory card" entry from the drop-down list.

4. Activate the option "Serial number is inserted when downloading to a device or a memory
card" if the serial number is to be inserted automatically during the uploading process
(dynamic binding). Assign a password using the "Define password" button to link the use
of a block additionally to the input of a password.
Activate the option "Enter serial number" if you want to manually bind the serial number of
the CPU or the SIMATIC memory card to a block (static binding).
5. You can now set up the know-how protection for the block in the "Know-how protection"
area.
Note
If you download a copy
-protected block to a device that does not match the specified
serial number, the entire download operation will be rejected. This means that blocks
without copy protection will also not be downloaded.
Removing copy protection
To remove copy protection, follow these steps:
1. Remove any existing know-how protection.
2. Open the properties of the block in question.
3. Select the "Protection" option under "General".
4. In the "Copy protection" area, select the "No binding" entry from the drop-down list.

Configuration control (option handling)
10
Introduction
Configuration control (option handling) is used to operate various standard machine
configuration levels in one project without changing the configuration or the user program.
Operating principle of configuration control
You can use configuration control to operate different standard machine configurations with
a single configuration of the ET 200SP distributed I/O system.
● A station master is configured in a project (maximum configuration). The station master
comprises all modules needed for all possible plant parts of a modular standard machine.
● The project's user program provides for several station options for various standard
machine configuration levels as well as selection of a station option. A station option
uses, for example, only some of the configured modules of the station master and these
modules are inserted in the slots in a different order.
● The standard machine manufacturer selects a station option for a configuration of the
standard machine. To do this, the project need not be modified, and it is not necessary to
load a modified configuration.
You use a control data record you have programmed to notify the CPU/interface module as
to which modules are missing or located on different slots in a station option as compared to
the station master. The configuration control does not have an impact on the parameter
assignment of the modules.
Configuration control allows you to flexibly vary the centralized/distributed configuration. This
is only possible if the station option can be derived from the station master.
The following figure shows three configurations of a standard machine with the
corresponding station options of the ET 200SP distributed I/O system.

Advantages
● Simple project management and commissioning by using a single STEP 7 project for all
station options.
● Simple handling for maintenance, versioning and upgrade:
● Hardware savings: Only those I/O modules are installed that are required for the
machine's current station option.
● Savings potential in the creation, commissioning and the documentation for standard
machines.
● Simple station expansion by using pre-wired empty slots. To expand, you simply
exchange the BU cover for the new model.

Introduction
Required steps
To create a control data record for the configuration control, follow these steps:
1. Create a PLC data type which contains the structure of the control data record.
The following figure shows a PLC data type "CTR_REC", which contains the structure of
the control data record for an ET 200SP interface module.
Figure 10-3 Creating control data record 196 using an IM 155-6 PN HF as an example
2. Create a global data block.
3. In the data block, create an array that is based on the created PLC data type.
Configuration control (option handling)
10.2 Creating the control data record
Distributed I/O system
178 System Manual, 02/2018, A5E03576849-AH
4. In the control data records, enter the slot assignments in the "Start value" column.
The figure below shows the global data block "ConfDB". The data block "ConfDB"
contains an array [0..5] of the PLC_DataType "CTR_REC".
Figure 10-4 Data block for configuration control
Rules
Observe the following rules:
● Slot entries in the control data record outside the station master are ignored by the
CPU/interface module.
● The control data record must contain the entries up to the last slot of the station option.
● Multiple configured slots may not be assigned to the same actual slot. In other words,
each station option slot may be present only once in the control data record.

Note
If a BU cover or no I/O module is plugged on a light

the additional function for the slot.
The function "Group diagnostics: Missing supply voltage L+" requ
ires proper assignment of
the slots to a shared supply voltage L+ (potential group). All light
-colored BaseUnits must be
known to the interface module. By entering 1 in the additional function, you make a light
-
colored BaseUnit known to the interface modul
e, even if an I/O module is not inserted.
Combination of configuration control and shared device (for PROFINET)
The configuration control function in a shared device is therefore only for the I/O modules of
the IO controller to which the interface module has subscribed. I/O modules that are
assigned to no controller or a different controller behave like a station without activated
configuration control.
You cannot make any change to the slot assignment for modules that are assigned to
another IO controller or are not assigned to an IO controller (shared device on module level).
The CPU assumes a one-to-one assignment for the modules.
If additional IO controllers subscribe to a module intended for configuration control (shared
device on submodule level), only one-to-one assignment is permitted for this module. It is not
possible to deselect such a module using the control data record (code 0 for this slot in the
control data record). This means the combination of "Configuration control" and "Shared
device on submodule level" is only possible to a limited extent.
Please note that all modules affected by the configuration control including all assigned
submodules are reset when you change the module assignment. Submodules that are
assigned to a second IO controller are affected as well.

Feedback data record for interface modules
Operating principle
The feedback data record informs you about the accuracy of the module assignment and
gives you the option of detecting assignment errors in the control data record. The feedback
data record is mapped via a separate data record 197 V2.0. The feedback data record exists
only with configured configuration control.
Slot assignment
The feedback data record refers to the configured station configuration and always includes
the maximum configuration limits. The maximum configuration limits comprise 13/49/81 slots
depending on the interface module in use. Partial reading of the feedback data record is
possible.

Transferring control data record in the startup program of the CPU
Required steps
Transfer the created control data record 196 to the CPU/the interface module using the
instruction WRREC (Write data record) instruction.
Parameters of the instruction WRREC
Below, you will find explanations of individual parameters of the WRREC instruction which
you must supply with specific values in the configuration control context. You can find
additional information on the WRREC instruction in the STEP 7 online help.
ID Hardware identifier
• Use the HW identifier of the CPU for the configuration control for centrally ar-
ranged modules.
If you have selected the CPU in the network view or device view, the HW identifier
is available in the
System constants
tab of the Inspector window.
Use the value of the system constant "Local~Configuration".
• Use the HW identifier of the interface module for the configuration control for dis-
tributed I/O.
If you have selected the interface module in the network view or device view, the
HW identifier is available in the
System constants
tab of the Inspector window.
Use the value of the system constant "<Name_of_the_interface_module>~Head".

80E2H Data record was transferred in the wrong OB context. The data
record must be transferred in the startup program.
80B8H Parameter error
A parameter error is caused by:
• Incorrect block ID in the header (not equal to 196)
• Invalid version identifier in the header
• A reserved bit was set
• A station master slot was assigned an invalid slot in the station
option
• Multiple slots in the station master are assigned to the same
slot in the station option
• For shared device on submodule level: Violation of defined
restrictions
Selection of the station option in the user program
In order for the CPU to know which station option you want to operate, you must set up a
selection option between the various control data records in the user program. You can
implement the selection, for example, via an Int tag which references an array element.
Note that the tag for selecting the control data record must be located in the retentive
memory area. If the tag is not retentive it will be initialized during the startup of the CPU and
thus be unavailable for selection of the station option.

10.3 Transferring control data record in the startup program of the CPU
Distributed I/O system
190 System Manual, 02/2018, A5E03576849-AH
Special aspects relating to the transfer of the control data record to the CPU
● If you have enabled configuration control, the CPU is not ready for operation without a
control data record. The CPU returns from startup to STOP if a valid control data record is
not transferred in the startup OB. The central I/O is not initialized in this case. The cause
for the STOP mode is entered in the diagnostics buffer.
Note
If an incorrect control data record is transferred to the CPU in the startup OB, the startup
of the CPU may be prevented.
In this case, perform a reset to factory settings of the CPU and then transfer a correct
control data record.
● The CPU processes the WRREC instruction for transfer of the control data record
asynchronously. For this reason, you must call WRREC in the startup OB repeatedly in a
loop until the output parameters "BUSY" or "DONE" indicate that the data record has
been transferred.
– Tip: To program the loop, use the SCL programming language with the REPEAT ...
UNTIL instruction.
REPEAT

ID := "Local~Configuration",
INDEX := 196,

● The control data record is stored retentively in the CPU. Note:
– The retentivity of the control data record is independent of the retentivity settings in the
STEP 7 memory area. This means that the memory area in which the control data
record is configured does not have to be configured as retentive for this purpose.
– If you write a control data record with modified configuration, the original data record
196 is deleted and the new data record 196 is saved retentively. The CPU will then
restart with the modified configuration.

Distributed I/O system
192 System Manual, 02/2018, A5E03576849-AH
Special aspects relating to the transfer of the control data record to the interface module
● If you have enabled configuration control, the ET 200SP station is not ready for operation
without a control data record. As long as no valid control data record has been
transferred, the I/O modules are considered as failed by the CPU and exhibit substitute
value behavior. The interface module continues to exchange data.
● The control data record is stored retentively in the interface module. Note:
– If there have been no changes to the configuration, you do not need to rewrite the
control data record 196 during restart.
– If you write a control data record with modified configuration to the interface module, it
will result in a station failure in the distributed I/O system. The original data record 196
is deleted and the new data record 196 is saved retentively. The station will then
restart with the modified configuration.

10.4 Behavior during operation
Distributed I/O system
System Manual, 02/2018, A5E03576849-AH 193
10.4
Behavior during operation
Effect of discrepancy between station master and station option
For the online display and for the display in the diagnostics buffer (module OK or module
faulty), the station master is always used and not the differing station option.
Example: A module supplies diagnostic information. This module is configured in slot 4 in the
station master, but is inserted in slot 3 in the station option (missing module; see example in
the next section). The online view (station master) shows a faulty module in slot 4. In the real
configuration, the module in slot 3 indicates an error via an LED display.
Response when modules are missing
If modules are entered as not present in the control data record, the automation system
behaves as follows:
● Modules designated as not present in the control data record do not supply diagnostics
and their status is always OK. The value status is OK.
● Direct write access to the outputs that are not present or write access to the process
image of the outputs that are not present: Remains without effect; no access error is
signaled.
● Direct read access to the inputs that are not present or read access to the process image
of the inputs that are not present: Value "0" is supplied; no access error is signaled.
● Write data record to module that is not present: Remains without effect; no error is
signaled.
● Read data record from module that is not present: An error is signaled because a valid
data record cannot be returned.

Note
Performing tests
You must ensure the safety of your plant. You therefore need to run a complete functional
test and make the necessary safety checks before the final commissioning of a plant.
Also allow for any possible foreseeab
le errors in the tests. This avoids endangering persons
or equipment during operation.
PRONETA
With SIEMENS PRONETA (PROFINET network analysis), you analyze the system network
during commissioning. PRONETA features two core functions:
● The topology overview independently scans PROFINET and all connected components.
● The IO check is a fast test of the wiring and the module configuration of a system.

Distributed I/O system
System Manual, 02/2018, A5E03576849-AH 213
11.5
Removing/inserting a SIMATIC memory card on the CPU
Requirement
The CPU only supports pre-formatted SIMATIC memory cards. If necessary, delete all
previously stored data before using the SIMATIC memory card. Additional information about
deleting the contents of the SIMATIC memory card can be found in the section, SIMATIC
memory card - overview (Page 240).
In order to work with the SIMATIC memory card, first ensure that the SIMATIC memory card
is not write-protected. If it is, move the slider out of the lock position.
Inserting the SIMATIC memory card
To insert a SIMATIC memory card, follow these steps:
1. Ensure that the CPU is either switched off or in STOP mode.
2. Insert the SIMATIC memory card, as depicted on the CPU, into the slot for the SIMATIC
memory card.
Figure 11-7 Slot for the SIMATIC memory card
3. Insert the SIMATIC memory card with light pressure into the CPU, until the SIMATIC
memory card latches.
Removal of the SIMATIC memory card
To remove a SIMATIC memory card, follow these steps:
1. Switch the CPU to STOP mode.
2. Press the SIMATIC memory card into the CPU with light pressure. After audible
unlatching of the SIMATIC memory card, remove it.
Only remove the SIMATIC memory card in POWER OFF or STOP mode of the CPU. Ensure
that no writing functions (online functions with the programming device, e.g. loading/deleting
a block, test functions) are active in STOP mode or were active before POWER OFF.

11.6 Operating modes of the CPU
Distributed I/O system
214 System Manual, 02/2018, A5E03576849-AH
Reactions after removing/inserting the SIMATIC memory card
Inserting and removing the SIMATIC memory card in STOP, STARTUP or RUN mode
triggers a re-evaluation of the SIMATIC memory card. The CPU hereby compares the
content of the configuration on the SIMATIC memory card with the backed-up retentive data.
If the backed-up retentive data matches the data of the configuration on the SIMATIC
memory card, the retentive data is retained. If the data differs, the CPU automatically
performs a memory reset (which means the retentive data is deleted) and then goes to
STOP.
The CPU evaluates the SIMATIC memory card, and this is indicated by the RUN/STOP LED
flashing.
Reference
Additional information on the SIMATIC memory card can be found in the SIMATIC memory
card (Page 240) section.
11.6
Operating modes of the CPU
Introduction
Operating modes describe the status of the CPU. The following operating modes are
possible using the mode selector:
● STARTUP
● RUN
● STOP
In these operating modes, the CPU can communicate, for example, via the PROFINET
interface.
The status LEDs on the front of the CPU indicate the current operating mode.
11.6.1
STARTUP mode
Function
Before the CPU starts to execute the cyclic user program, a startup program is executed.
By suitably programming startup OBs, you can specify initialization tags for your cyclic
program in the startup program. You have the option of programming no, one or several
startup OBs.

to the RUN mode.
● The CPU always starts up in warm restart mode.
– The non-retentive bit memory, timers and counters are initialized.
– The non-retentive tags in data blocks are initialized.
● During startup, cycle time monitoring is not yet running
● The startup OBs are executed in the order of the startup OB numbers. All startup OBs
that you have programmed are executed, regardless of the selected startup mode.
● The following OBs can be started during startup, if a corresponding event occurs:
– OB 82: Diagnostics interrupt
– OB 83: Pull/plug interrupt for modules
– OB 86: Rack error
– OB 121: Programming error (only for global error handling)
– OB 122: I/O access error (only for global error handling)
You can find a description of how to use global and local error handling in the STEP 7
online help.
No other OBs can be started until after the transition to RUN mode.
Response when expected and actual configurations do not match
The configuration downloaded to the CPU represents the expected configuration. The actual
configuration is the actual configuration of the ET 200SP distributed I/O system. If the
expected configuration and the actual configuration do not match, the setting of the
"Comparison preset to actual configuration" parameter determines the reaction of the CPU
(see section Operating mode transitions (Page 218)).

Canceling a startup
If errors occur during startup, the CPU cancels the startup and returns to STOP mode.
The CPU does not execute a startup or cancels a startup under the following conditions:
● If no SIMATIC memory card is inserted or an invalid SIMATIC memory card is inserted.
● If no hardware configuration has been downloaded.
Setting the startup behavior
To set the startup behavior, follow these steps:
1. In the device view of the STEP 7 hardware network editor, select the CPU.
2. In the properties under "General" select the "Startup" area.
Figure 11-8 Setting the startup behavior
①
Sets the startup type after POWER ON
②
Defines the startup behavior when a module in a slot does not correspond to the confi
g-
ured module. You can set this parameter centrally, on the CPU or for each module.
When you change the setting for a module, the
setting made centrally for this module no
longer applies.
•
Startup CPU only if compatible: In this setting a module on a configured slot has to be
compatible with the configured module. Compatible means that the module matches
in terms of the number of inputs and outputs and with respect to its electrical and
functional properties.
•
Startup CPU even if mismatch: With this setting the CPU starts up regardless of the
type of module plugged in.
③
Specifies a maximum period (default: 60000
ms) in which the I/O must be ready for op-
eration. The CPU changes to RUN.
If the central and distributed I/O is not ready for operation within the configuration time,
the startup characteristics of the CPU depen
ds on the setting of the "Comparison preset
to actual configuration" parameter.

Example for the "Comparison preset to actual configuration" parameter
"Startup CPU only if compatible":
The input module DI 16x24VDC ST with 16 digital inputs is a compatible replacement for the
input module DI 8x24VDC ST with 8 digital inputs, because the pin assignment and all the
electrical and functional properties match.
"Startup CPU even if mismatch":
Instead of a configured digital input module, you insert an analog output module or no
module is present in this slot and thus in all subsequent slots. Although the configured inputs
cannot be accessed, the CPU starts up.
Note that the user program cannot function correctly in this case and take the appropriate
measures.

STOP mode
Function
The CPU does not execute the user program in STOP mode.
All outputs are disabled or react according to the parameter settings for the particular I/O
module: They provide a substitute value as set in the parameters or retain the last value
output keeping the controlled process in a safe operating status.
In STOP mode, the motor starter responds according to how it was parameterized for the
CPU STOP state. The CPU STOP state can be circumvented with the manual local control
(Local Control) function. If the CPU is switched off, a motor can be switched on in the motor
starter's commissioning mode.

Distributed I/O system
218 System Manual, 02/2018, A5E03576849-AH
Execution of the user program
Once the CPU has read the inputs, the cyclic program is executed from the first instruction to
the last instruction.
If you have configured a minimum cycle time, the CPU will not end the cycle until this
minimum cycle time is finished even if the user program is completed sooner.
A cycle monitoring time is set to ensure that the cyclic program is completed within a
specified time. You can change the cycle monitoring time to suit your requirements. If the
cyclic program has not finished running within this time, the system responds with a time
error.
Further events such as hardware interrupts and diagnostics interrupts can interrupt the cyclic
program flow and prolong the cycle time.

CPU memory reset
Basics of a memory reset
A memory reset on the CPU is possible only in the STOP mode.
When memory is reset, the CPU is changed to a so-called "initial status".
This means that:
● An existing online connection between your programming device/PC and the CPU is
terminated.
● The content of the work memory and the retentive and non-retentive data (applies only to
manual memory reset by the user) are deleted.
● The diagnostics buffer, time of day, IP address and the device name are retained.
● Subsequently the CPU is initialized with the loaded project data (hardware configuration,
code and data blocks, force jobs). The CPU copies this data from the load memory to the
work memory.
Result:
– If you set an IP address in the hardware configuration ("Set IP address in the project"
option) and a SIMATIC memory card with the project is in the CPU, this IP address is
valid after the memory reset.
– Data blocks no longer have current values but rather their configured start values.
– Force jobs remain active.
How can I tell if the CPU is performing a memory reset?
The RUN/STOP LED flashes yellow at 2 Hz. After completion the CPU goes into STOP
mode, and the RUN/STOP LED is switched on (permanently lit yellow).

Possible cause of an automatic memory reset
The CPU executes an automatic memory reset if an error occurs that prevents normal
further processing.
Causes for such errors can be:
● User program is too large, and cannot be completely loaded into work memory.
● The project data on the SIMATIC memory card is corrupt, for example, because a file was
deleted.
● If you remove or insert the SIMATIC memory card and the backed-up retentive data
differs in structure from that of the configuration on the SIMATIC memory card.

To reset the CPU memory using the mode selector, proceed as follows:
1. Set the mode selector to the STOP position.
Result: The RUN/STOP LED lights up yellow.
2. Set the mode selector to the MRES position. Hold the selector in this position until the
RUN/STOP LED lights up for the 2nd time and remains continuously lit (this takes three
seconds). After this, release the switch.
3. Within the next three seconds, switch the mode selector back to the MRES position, and
then back to STOP again.
Result: The CPU executes memory reset.
For information on resetting the CPU to factory settings, refer to the section Resetting the
CPU to factory settings (Page 264).
Procedure using STEP 7
For a memory reset of the CPU using STEP 7 proceed as follows:
1. Open the "Online Tools" task card of the CPU.
2. Click the "MRES" button in the "CPU control panel" pane.
3. Click "OK" in response to the confirmation prompt.

Reassigning parameters during operation
Introduction
You have the option of reassigning the parameters for the ET 200SP I/O modules during
operation.
Changing parameters during operation
You make the parameter settings of the I/O modules using data records. Each I/O module
has a separate data record. The instruction "WRREC" applies the changed parameters to
the I/O module.
If you are using the CPU as an I-device, you reassign the parameters of the I/O modules via
the I-device.
Note
If you write data records from the user program to the modules of the distributed I/O, make
sure that these modules actually exist and are available. You c
an evaluate OB83 for this
purpose. After inserting a module, the CPU does not call OB83 until the module has started
up and its parameters are assigned. This ensures the execution of the data record
operations without errors.
Note
You need to transfer
the new parameters with the "WRREC" instruction after a POWER
OFF/POWER ON of the ET
200SP.
Instruction for parameter assignment
The following instruction is provided for assigning parameters to the I/O module in the user
program:

Reading out and entering I&M data
I&M data
I&M identification data is information which is stored on the module either as read-only data
(I-data) or read/write data (M-data).
Identification data (I&M0):
Manufacturer information about the module that can only be read
and is in part also printed on the housing of the module, for example, article number and
serial number.
Maintenance data (I&M1, 2, 3):
Plant-dependent information, e.g. installation location.
Maintenance data is created during configuration and written to the module.
All modules of the ET 200SP distributed I/O system support identification data (I&M0 to
I&M3).
The I&M identification data supports you in the following activities:
● Checking the plant configuration
● Locating hardware changes in a plant
● Correcting errors in a plant
Modules can be clearly identified online using the I&M identification data.
STEP 7 allows you to read the identification I&M data (see STEP 7 online help).
Note
The BusAdapter and the interface module IM
155-6 PN HF support the identification data
I&M0 to I&M4 (signature).

Example: Read out firmware version of the CPU with Get_IM_Data
Automation task
You want to check whether the modules in your automation system have the current
firmware. The firmware version of the modules can be found in the I&M 0 data. The IM 0
data are the basic information of a device and contain information such as the manufacturer
ID, order number, serial number and the hardware and firmware version.
To read out the I&M 0 data, use the "Get_IM_Data" instruction. You read the I&M 0 data of
all the modules in the user program of the CPU via "Get_IM_Data" instructions and store
them in a data block.
Conditions and parameters
To read out the I&M data of the CPU, use the following block parameters of the
"Get_IM_Data" instruction:
● LADDR: Enter the HW ID of the module at the block parameter "LADDR".
● IM_TYPE: Enter the I&M data number (e.g. "0" for I&M 0 data) at the "IM_TYPE" block
parameter.
● DATA: Area for storing the read I&M data (for example. in a global data block). Store the
I&M 0 data in an area of the data type "IM0_Data".
This example shows you how to read out the I&M 0 data of an ET 200SP CPU. To read out
the I&M 0 data of a different module, simply use the HW ID of the module at the parameter
LADDR.
Solution
To read out the I&M 0 data of the CPU, follow these steps:
1. Create a global data block to store the I&M 0 data.
2. Create a structure of the data type "IM0_Data" in the global data block. You can assign
any name to the structure ("imData") in this case.
Figure 11-10 Example: Data block for I&M data
3. Create the "Get_IM_Data" instruction in the user program, e.g. in OB 1.

Overview
Backup from online device
You will make a number of changes to your plant over time, for example, add new devices,
replace existing devices or adapt the user program. If these changes result in undesirable
behavior, you can restore the plant to an earlier state. Before you load a changed
configuration to the CPU, first use the option "Backup from online device" to create a
complete backup of the current device status.
Upload from device (software)
With the option "Upload from device (software)", you load the software project data from the
CPU to an existing CPU in the project.
Upload device as new station
If you are operating a new programming device/PC in the plant, the STEP 7 project that was
used to create the plant configuration might not be available. In this case you can use the
option "Upload device as new station" to load the device's data into a project in your PG/PC.
Snapshot of the monitor values
You can use the option "Snapshot of the monitor values" to backup the current values of the

Emergency address (emergency IP)
The emergency address (emergency IP address) of a CPU was conceived for diagnostic and
downloading functions, e.g. if the CPU can no longer be reached via the IP protocol due to
loading of an incorrect project. You can find information on the emergency address in the
following FAQ on the Internet
(https://support.industry.siemens.com/cs/ww/en/view/97649773).
Archiving multilingual project texts
When you configure a CPU, different categories of texts come into being, e.g.
● Object names (names of blocks, modules, tags, etc.)
● Comments (for blocks, networks, watch tables, etc.)
● Messages and diagnostic texts
Texts are provided by the system (e.g. diagnostic buffer texts) or are created during
configuration (e.g. messages).
In a project, texts exist in one single language or in several languages after a translation
process. You can maintain project texts in all languages, which are at your disposal in the
project navigator (Languages & Resources > Project Texts). The texts arising during
configuration can be loaded into the CPU.
The following texts containing the project data are loaded into the CPU in the chosen
languages and are also used by the Web server:
● Diagnostic buffer texts (not editable)
● Module status texts (not editable)
● Message texts with associated text lists
● Tag comments and step comments for S7 GRAPH and PLC Code Viewer
● Comments in watch tables
The following texts containing the project languages are also loaded into the CPU in the
chosen languages, but are not used by the Web server:
● Comments in tag tables (for tags and constants)
● Comments in global data blocks
● Comments of elements in block interfaces of FBs, FCs, DBs and UDTs
● Network titles in data blocks that are written in ladder logic (LAD), function block diagram
(FBD) or statement list (STL)
● Block comments
● Network comments
● Comments of LAD and FBD elements

The CPUs support archiving of multilingual project texts in up to three different project
languages. If the project texts belonging to a specific project language nevertheless exceed
the memory space reserved for them, it is not possible to load the project into the CPU. The
operation is canceled with a message indicating that not enough free storage space is
available. In such a case, take measures to reduce the required storage space, for example
by shortening comments.
Note
Size of the SIMATIC memory card
If the storage space needed to load projects exceeds the storage space available on the
SIMATIC memory card in use, loading into the CPU is canceled with an error message.
Therefore, make sure that there is enough available storage space on your SIMATIC
me
mory card for loading projects.

Time synchronization
NTP procedure
All CPUs are equipped with an internal clock. The clock always shows the time-of-day with a
resolution of 1 millisecond and the date including the day of the week. The time adjustment
for daylight saving time is also taken into account.
You can synchronize the time of the CPUs with an NTP server in NTP mode (NTP: Network
Time Protocol).
In NTP mode, the device sends time queries at regular intervals (in client mode) to the NTP
server in the subnet (LAN). Based on the replies from the server, the most reliable and most
accurate time is calculated and the time on the CPU is synchronized. The advantage of this
mode is that it allows the time to be synchronized across subnets. You can configure the IP
addresses of up to a maximum of four NTP servers. You address a communications
processor or an HMI device, for example, as sources for time synchronization via the IP
addresses.
The update interval defines the interval between the time queries (in seconds). The value of
the interval ranges between 10 seconds and one day. In NTP mode, it is generally UTC
(Universal Time Coordinated) that is transferred; this corresponds to GMT (Greenwich Mean
Time).

SIMATIC memory card - overview
Introduction
The CPU uses a SIMATIC memory card as a memory module. The SIMATIC memory card
is a preformatted memory card compatible with the Windows file system. The memory card
is available in different memory sizes and can be used for the following purposes:
● Transportable data carrier
● Program card
● Firmware update card
● Service data card
If you transfer the user program to the CPU via an online connection, it is written to the
SIMATIC memory card, which must be in the card slot of the CPU for this to work.
You can also write the SIMATIC memory card in the PG/PC. A commercially available SD
card reader is required to write / read the SIMATIC memory card with the programming
device / PC. This is used to copy files directly to the SIMATIC memory card using the
Windows Explorer, for example.
A SIMATIC memory card is absolutely required in order to operate the CPU.

Use the serial number for copy protection
You can set up copy protection for CPUs which binds execution of the block to a specific
SIMATIC memory card. Configuration is carried out in STEP 7 in the properties of the block
"Bind to serial number of the SIMATIC memory card".
You can only execute the block if it is on the SIMATIC memory card with the specified serial
number (see section Copy protection (Page 170)).
Removing a SIMATIC memory card
Only remove the SIMATIC memory card in POWER OFF or STOP mode of the CPU. Make
sure that no writing functions (e.g. loading/deleting a block) are active in STOP mode, or
were active at POWER OFF. To do this, disconnect the communication connections.
If you remove the SIMATIC memory card during a write process, the following problems can
occur:
● The data contents of a file are incomplete.
● The file is no longer readable, or no longer exists.
● The entire content of the card is corrupted.
Inserting the SIMATIC memory card in the CPU in STOP mode triggers a re-evaluation of
the SIMATIC memory card. The CPU hereby compares the content of the configuration on
the SIMATIC memory card with the backed-up retentive data. If the backed-up retentive data
matches the data of the configuration on the SIMATIC memory card, the retentive data is
retained. If the data differs, the CPU automatically performs a memory reset (which means
the retentive data is deleted) and then goes to STOP.
Also note the following FAQ on the Internet
(https://support.industry.siemens.com/cs/ww/en/view/59457183) in connection with the
removal of the SIMATIC memory card.

Removing a SIMATIC memory card from Windows computers
If you are using the card in a commercially available card reader under Windows, use the
"Eject" function before you remove the card from the card reader. If you remove the card
without using the "Eject" function, you may lose data.
Deleting the contents of the SIMATIC memory card
You have the following options for deleting the content of the SIMATIC memory card:
● Delete files using Windows Explorer
● Format with STEP 7
Note
If you format the card with Windows utilities, you will render the SIMATIC memory card
unusable as a storage medium for a CPU.
Deletion of files and folders is permitted, with the exception of the "__LOG__" and
"crdinfo.bin" system f
iles. The CPU needs these system files. If you delete the files, you will
no longer be able to use the SIMATIC memory card with the CPU.
If you have deleted the "__LOG__" and "crdinfo.bin" system files, format the SIMATIC
memory card as described in the fo
llowing section.
Formatting the SIMATIC memory card
Note
You may only format a SIMATIC memory card in the CPU; otherwise, the SIMATIC memory
card cannot be used in the CP
U.
If you want to format the SIMATIC memory card using STEP 7, an online connection to the
relevant CPU must exist. The CPU is in STOP mode.
Follow these steps to format a SIMATIC memory card with inserted SIMATIC memory card:
1. Open the Online and Diagnostics view of the CPU (either from the project context or via
"Accessible devices").
2. In the "Functions" folder, select the "Format memory card" group.
3. Click the "Format" button.
4. Click "Yes" in response to the confirmation prompt.
Result:
● The SIMATIC memory card is formatted for use in the CPU.
● The data on the CPU is deleted with the exception of the IP address.

Transferring objects from the project to a SIMATIC memory card
When the SIMATIC memory card is inserted into the programming device or into an external
card reader, you can transfer objects from the project tree (STEP 7) to the SIMATIC memory
card as follows:
● Individual blocks (multiple selection possible)
In this case, the transfer is consistent, i.e. the function takes dependencies between
blocks due to block calls into account.
● CPU folder
In this case, all runtime-relevant objects including blocks and the hardware configuration
are transferred onto the SIMATIC memory card - just as when downloading.
● Service data
In this case, the service data previously saved (see chapter Reading out/saving service
data (Page 280)) is transferred to the SIMATIC memory card.
To perform a transfer, you can transfer the objects by dragging and dropping, or use the
"Card Reader/USB memory > Write to memory card" command in the "Project" menu.

● CPU/interface module HF, HS: You can remove and insert any number of I/O
modules/motor starters.
● ST, BA interface module: You can only remove and insert one I/O module/motor starter.
This section provides further information on removing and inserting I/O modules/motor
starters.
I/O modules/motor starters must not be removed or inserted during operation (RUN

continue because the current transformer is isolated safely.
However, the measuring voltage on the module, at connec-
tions UL1-UL3, still needs to be isolated.

NOTICE
Risk of hazardous system states
If you remove and insert digital output modules with the load switched on or technology
modules with the supply voltage switched on, this can result in hazardous system states.
The ET 200SP distributed I/O system or the connected sensors may be damaged as a
result.
Therefore, a digital output module may only be inserted and removed when the load is
switched off and a technology module may only be inserted and removed when the supply
voltage is switched off.
NOTICE
Risk of hazardous system states
If you remove and insert the AI Energy Meter ST with the primary-side voltage switched on
at the current transformer, this can result in hazardous system states.
The ET 200SP distributed I/O system may be damaged as a result.
For this reason, remove and insert the AI Energy Meter ST
• Only when measuring voltage on primary side is switched off, or
• Only when a special current transformer terminal is used which short-circuits the
secondary end of the transformer when a module is removed.
Do not remove or insert the AI Energy Meter ST until you have removed this current
transformer terminal. With the special terminal, the process can continue because the
current transformer is isolated safely. However, the measuring voltage on the module at the
connections UL1-UL3 still needs to be isolated.
WARNING
Risk of injury from automatic restart
Inserting a motor starter can result in dangerous system states. The motor starter can
restart again autonomously if an ON command is active.
This can result in serious injury caused by connected devices that are automatically started
up.
Withdraw and insert a motor starter only after disconnecting the load.

NOTICE
Reaction of the CPU to removal and insertion of the ET 200SP server module
Please note that the backplane bus is deactivated when you remove the server module,
regardless of the CPU operating state. Also note that the outputs do not adopt their
configured substitute value behavior when you remove the server module.
This means you should not remove the server module in the CPU operating states
STARTUP, RUN and STOP. If you have nevertheless removed the server module, perform
a POWER OFF/POWER ON after you have inserted the server module again.
Removing and inserting BusAdapter or CM DP module
Do not remove or insert the BusAdapter or CM DP module when the supply voltage is
switched on. If you remove the BusAdapter or CM DP module after CPU startup, the supply
voltage of the BusAdapter or CM DP module is switched off automatically. To switch on the
supply voltage again, you need to perform a POWER OFF/POWER ON after inserting the
BusAdapter/CM DP module.

another I/O module/motor starter, this results in a station stop of the ET 200SP distributed
I/O system:
– All I/O modules/motor starters of the ET 200SP distributed I/O system fail → Substitute
value behavior.
– The interface module continues to exchange data with the IO controller and report
diagnostics.
Note
If you want to replace several I
/O modules/motor starters during operation, you must
replace them one after the other.
2. If you insert all but one of the I/O modules/motor starters withdrawn during operation, all
I/O modules will start up again.
Note
I/O modules/motor starters inser
ted in empty slots and then removed are also regarded
as withdrawn during operation.
3. After a POWER OFF/POWER ON of the supply voltage 1L+ of the interface module, all

Changing the type of an I/O module
Introduction
The coding element is a two-part element. When shipped from the factory, both parts are in
the I/O module. When an I/O module is installed for the first time, a part of the coding
element clicks into the BaseUnit. This mechanically prevents the insertion of a different
module type.
There are two versions of the ET 200SP distributed I/O system:
● Mechanical coding element: Ensures the mechanical coding described above.
● Electronic coding element: In addition to the above-mentioned mechanical coding, this
version also has an electronic, rewritable memory for module-specific configuration data
(such as the F-destination address for fail-safe modules, parameter data for IO link
master).
Requirement
Refer to section Application planning (Page 36).
NOTICE
Do not manipulate the coding element
Making changes to the coding element may cause dangerous conditions in your plant
and/or result in damage to the outputs of the ET 200SP distributed I/O system.
To avoid physical damage, do not manipulate the coding.
Changing the type of an I/O module
You have already removed the I/O module.
To make a type change for an I/O module, follow these steps:
1. Push the coding element out of the BaseUnit using a screwdriver.
2. Put the coding element back onto the removed I/O module.
3. Insert the new I/O module (other module type) into the BaseUnit until
you hear it click into place.

Replacing an I/O module
Introduction
When an I/O module is installed for the first time, a part of the coding element clicks into the
BaseUnit. When you replace an I/O module with the same type of module, the correct coding
element is already present in the BaseUnit.
Requirement
Refer to section Application planning (Page 36).
Replacing an I/O module
You have already removed the I/O module.
To replace an I/O module, follow these steps:
1. Remove the coding element (part) from the underside of the new I/O module.
2. Insert the new I/O module (same module type) into the BaseUnit until you hear it click into
place.

The CPU can be reset to its delivery state using "Reset to factory settings". The function
deletes all information saved internally on the CPU.
Recommendation:
If you want to remove a PROFINET CPU and use it elsewhere with a different program, or
put it into storage, we recommend that you reset the CPU to its factory settings. When
restoring the factory settings, remember that you also delete the IP address parameters.
Options for resetting a CPU to factory settings
The following options are available for resetting the CPU to its factory settings:
● Using the mode selector
● Using STEP 7
● Using the SIMATIC Automation Tool
Procedure using the mode selector
Make sure that there is no SIMATIC memory card in the CPU and that the CPU is in STOP
mode (the RUN/STOP LED is lit yellow).

Perform a reset to factory settings when there is no SIMATIC memory card inserted as
follows:
1. Set the mode selector to the STOP position.
Result: The RUN/STOP LED lights up yellow.
2. Set the mode selector to the MRES position. Hold the mode selector in this position until
the RUN/STOP LED lights up for the 2nd time and remains continuously lit (after three
seconds). After this, release the switch.
3. Within the next three seconds, switch the mode selector back to the MRES position, and
then back to STOP again.
Result: The CPU executes the "Reset to factory settings", during which time the RUN/STOP
LED flashes yellow. When the RUN/STOP LED lights up yellow, the CPU has been reset to
factory settings and is in the STOP mode. The "Reset to factory settings" event is entered in
the diagnostics buffer.
Note
The IP address of the CPU is also deleted when the CPU is reset to the factory settings
through the mode selector.
For information on the memory reset of the CPU, refer to the section CPU memory reset
(Page 221).

13.8 Reaction to faults in fail-safe modules and fail-safe motor starters
Distributed I/O system
270 System Manual, 02/2018, A5E03576849-AH
13.8
Reaction to faults in fail-safe modules and fail-safe motor starters
Safe state (safety concept)
The basic principle behind the safety concept is the existence of a safe state for all process
variables.
Note
For digital F
-modules, this safe state is the value "0". This applies to both sensors and
actuators. In the case of the fail
-safe motor starters, the load is shut down in a fail-safe
manner.
Fault reactions and startup of the F-system
The safety function means that fail-safe modules use substitute values (safe state) instead of
process values (
passivation of the fail-safe module
) in the following situations:
● When the F-system is started up
● If errors are detected during safety-related communication between the F-CPU and the
F-module via the PROFIsafe safety protocol (communication error)
● If F-I/O faults or channel faults are detected (e.g. crossover or discrepancy errors)
Detected faults are written to the diagnostic buffer of the F-CPU and communicated to the
safety program in the F-CPU.
F-modules cannot save errors as retentive data. After a POWER OFF / POWER ON, any
faults still existing are detected again during startup. However, you have the option of saving
faults in your safety program.
WARNING
For channels that you set to "deactivated" in STEP 7, no diagnostic response or error
handling is triggered when a channel fault occurs, not even when such a channel is
affected indirectly by a channel group fault ("Channel activated/deactivated" parameter).
Remedying faults in the F-system
To remedy faults in your F-system, follow the procedure described in IEC 61508-1:2010
section 7.15.2.4 and IEC 61508-2:2010 section 7.6.2.1 e.
The following steps must be performed:
1. Diagnosing and repairing the fault
2. Revalidation of the safety function
3. Recording in the service report
Maintenance
13.8 Reaction to faults in fail-safe modules and fail-safe motor starters
Distributed I/O system
System Manual, 02/2018, A5E03576849-AH 271
Substitute value output for fail-safe modules
In the case of F-modules
with inputs
, if there is passivation, the F-system provides substitute
values (0) for the safety program instead of the process data pending at the fail-safe inputs.
In the case of F-modules with outputs
, if there is passivation, the F-system transfers
substitute values (0) to the fail-safe outputs instead of the output values provided by the
safety program. The output channels are de-energized. This also applies when the F-CPU
goes into STOP mode. Assignment of substitute values is not possible.
Depending on which F-system you are using and the type of fault that occurred (F-I/O fault,
channel fault or communication error), substitute values are used either for the relevant
channel only or for all channels of the relevant fail-safe module.
Reintegration of a fail-safe module
The system changes from fail-safe to process values (reintegration of an F-module) either
automatically or only after user acknowledgment in the safety program. If channel faults
occur, it may be necessary to remove and reinsert the F-module. A detailed listing of faults
requiring removal and insertion of the F-module can be found in the section Diagnostic
messages of the respective F-module.
After reintegration, the following occurs:
● In the case of an F-module with inputs, the process data pending at the fail-safe inputs is
made available to the safety program again
● In the case of an F-module with outputs, the output values provided in the safety program
are transferred to the fail-safe outputs again
Additional information on passivation and reintegration
For additional information on passivation and reintegration of F-I/O, refer to the SIMATIC
Safety, Configuring and Programming
(http://support.automation.siemens.com/WW/view/en/54110126) manual.
Behavior of the fail-safe module with inputs in the event of a communication disruption
F-modules with inputs respond differently to communication errors compared to other errors.
If a communication error is detected, the current process values remain set at the inputs of
the F-module. There is no passivation of the channels. The current process values are
passivated in the F-CPU.

values of operands and the results of logic operations (RLO) allowing you to recognize and
fix logical errors in your program.
Note
Restrictions for the "Program status" function
Monitoring loops can clearly increase the cycle time, depending on the number of tags
monitored and dependi
ng on the actual number of loops run through.
WARNING
Testing with program status
A test with the "Program status" function can produce serious property damage and
personal injury in the event of malfunctions or program errors.
Make sure that you take appropriate measures to exclude the risk of hazardous conditions
occurring before running a test with the "Program status" function.
Testing with breakpoints
With this test option, you set breakpoints in your program, establish an online connection,
and enable the breakpoints on the CPU. You then execute a program from one breakpoint to
another.
Requirements:
● Setting breakpoints is possible in the programming language SCL or STL.
Testing with breakpoints provides you with the following advantages:
● Localization of logic errors step by step
● Simple and quick analysis of complex programs prior to actual commissioning
● Recording of current values within individual executed loops
● Use of breakpoints for program validation also possible in SCL/STL networks within
LAD/FBD blocks
Note
Restriction during testing with breakpoints
When you test with breakpoints, there is a risk of overwriting the cycle time of the CPU.

security program:
•
Sequence of F cycle time monitoring
•
Error in communication with the fail-safe I/O
•
Error during safety-oriented CPU-CPU communication
•
internal CPU error
If you still wish to use breakpoints for testing, you must deactivate
the safety mode beforehand. This will result in the following errors:
•
Error in communication with the fail-safe I/O
•
Error during safety-oriented CPU-CPU communication

Testing with watch tables
The following functions are available in the watch table:
● Monitoring of tags
With watch tables, you can monitor the current values of individual tags of a user program
or a CPU on the PG/PC and Web server. For the Web server to be able to display the
value of tags, you must specify a symbolic name for each tag in the "Name" column of the
watch table.
You can monitor the following operand areas:
– Inputs and outputs (process image) and bit memory
– Contents of data blocks
– Peripheral inputs and peripheral outputs
– Timers and counters
● Modifying tags
Use this function to assign fixed values to the individual tags of a user program or CPU.
Modifying is also possible for testing with program status.
You can control the following operand areas:
– Inputs and outputs (process image) and bit memory
– Contents of data blocks
– Peripheral inputs and peripheral outputs (for example, %I0.0:P, %Q0.0:P)
– Timers and counters
● "Enable peripheral outputs" and "Control immediately"
These two functions enable you to assign fixed values to individual peripheral outputs of
a CPU in the STOP mode. You can also use them to check your wiring.

Testing with the force table
The following functions are available in the force table.
● Monitoring of tags
With force tables, you can display the current values of individual tags of a user program
or a CPU on the PG/PC and Web server. You can monitor the table with or without a
trigger condition. For the Web server to be able to display the value of tags, you must
specify a symbolic name for each tag in the "Name" column of the force table.
You can monitor the following tags:
– Bit memory
– Contents of data blocks
– Peripheral inputs (e.g. %I0.0:P)
● Modifying tags
With this function, you assign fixed values to the individual tags of a user program or a
CPU on the PG/PC and Web server. Modifying is also possible for testing with program
status.
You can control the following tags:
– Bit memories
– Contents of data blocks
– Peripheral inputs (e.g. %I0.0:P)
● Forcing of peripheral inputs and peripheral outputs
You can force individual peripheral inputs or peripheral outputs.
– Peripheral inputs: Forcing of peripheral inputs (for example %I0.0:P) represents the
"bypassing" of sensors/inputs by specifying fixed values to the program. Instead of the
actual input value (via process image or via direct access) the program receives the
force value.
– Peripheral outputs: Forcing of peripheral outputs (for example %Q0.0:P) represents
the "bypassing" of the complete program by setting fixed values for the actuators.
The force table offers the advantage both of being able to simulate different test
environments and also of being able to overwrite tags in the CPU with a fixed value. Thus,
you have a possibility of intervening in the ongoing process to regulate it.

Distributed I/O system
278 System Manual, 02/2018, A5E03576849-AH
Difference between modifying and forcing
The fundamental difference between the modifying and forcing functions consists in the
storage behavior:
● Modifying: Modifying of tags is an online function and is not stored in the CPU. You can
end modifying of tags in the watch table or by disconnecting the online connection.
● Forcing: A force job is written to the SIMATIC memory card and is retained after a
POWER OFF. You can only end the forcing of peripheral inputs and peripheral outputs in
the force table.
Testing with PLC tag table
You can monitor the data values that tags currently assume in the CPU directly in the PLC
tag table. To do this, open the PLC tag table and start monitoring.
Additionally, you have a possibility of copying PLC tags to a monitoring or force table and of
monitoring, controlling or forcing them there.
Testing with data block editor
Various possibilities of monitoring and controlling tags are at your disposal in the data block
editor. These functions directly access the current values of the tags in the online program.
Current values are the values that the tags assume at the current time during program
execution in the CPU's work memory. The following functions for monitoring and control are
possible via the data block editor:
● Monitoring tags online
● Controlling individual actual values
● Creating a snapshot of the actual values
● Overwriting actual values with a snapshot
Note
Setting data values during commissioning
During commissioning of a system, data values often have to be adjusted to optimally adapt
the program to the general conditions prevailing locally. To this end, the declaration table
offers a few functions for data blocks.

Testing with the LED flash test
In many online dialogs, you can perform an LED flash test. This function is useful, for
example, when you are not sure which device in the hardware configuration corresponds to
the device currently selected in the software.
When you click the "Flash LED" button, an LED flashes on the currently selected device. In
the case of the CPU, the RUN/STOP, ERROR and MAINT LEDs flash. They flash until you
cancel the flashing test.
Testing with trace function
The trace function is used to record the CPU tags, depending on the settable trigger
conditions. Tags are, for example, the drive parameters or system and user tags of a CPU.
The CPU saves the recordings. You can display and evaluate the recordings with STEP 7,
if necessary.
The trace function can be called from the CPU's folder in the project tree, under the name
"Traces".
In connection with trace functions, also pay attention to the following FAQ on the Internet
(https://support.industry.siemens.com/cs/ww/en/view/102781176).
Simulation
With STEP 7 you can run and test the hardware and software of the project in a simulated
environment. Start the simulation using the menu command "Online" > "Simulation" > "Start".

Reading out/saving service data
Service data
In addition to the contents of the diagnostics buffer, the service data contains a wide range of
extra information about the internal status of the CPU. If a problem occurs the CPU that
cannot be solved with other methods, send the service data to our Service & Support team.
The service data allows Service & Support to run fast analysis of the problems that have
occurred.
Note
You cannot simultaneously execute a download to the device while reading out the service
data of the CPU.
Methods of reading service data
You can read service data with:
● The Web server
● STEP 7
● the SIMATIC memory card
Procedure using the Web server
To read service data using the Web server, follow these steps:
1. Open a Web browser that is suitable for communication with the CPU.
2. Enter the following address in the address bar of the web browser:
https://<CPU IP address>/save_service_data, e.g. https://172.23.15.3/save_service_data
3. The service data page will appear on your screen, with a button for saving the service
data.

Result: The CPU stores the data in a .dmp file with the following naming convention:
"<Article number> <Serial number> <Time stamp>.dmp". The file name cannot be changed.
Note
If you have defined your user page as the Web server's home page, direct access to the
service data by entering the CPU's IP address is not possible. You will find further
information on reading out service data via a user
-defined page in the Web server
(
http://support.automation.siemens.com/WW/view/en/59193560) function manual.
Procedure using STEP 7
A description of how to save service data is available under the keyword "Save service data"
in STEP 7 online help.
Procedure via the SIMATIC memory card
Use the SIMATIC memory card to read out the service data only if you are no longer able to
communicate with the CPU via Ethernet. In all other cases it is preferable to read out the
service data via the Web server or STEP 7.
The procedure using the SIMATIC memory card is more time-consuming than the other
options for reading out the service data. You must also ensure before reading out that there
is sufficient memory space on the SIMATIC memory card.
To read service data using the SIMATIC memory card, follow these steps:
1. Insert the SIMATIC memory card into the card reader of your PC / programming device.
2. Open the job file S7_JOB.S7S in an editor.
3. Overwrite the entry PROGRAM with the string DUMP in the editor.
Do not use any spaces/line breaks/quotation marks to ensure that the file size is exactly
4 bytes.
4. Save the file under the existing file name.
5. Ensure that the SIMATIC memory card is not write protected and insert it in the card slot
of the CPU. Pay attention to the procedure described in Removing/inserting the SIMATIC
memory card on the CPU (Page 213).
Result: The CPU writes the service data file DUMP.S7S to the SIMATIC memory card and
remains in STOP mode.
The transfer of the service data has been completed as soon as the STOP LED stops
flashing and lights up continuously. If the transfer was successful, only the STOP LED lights
up. If transfer was not successful, the STOP LED and the ERROR LED flash. In case of an
error, the CPU stores a text file with a note on the error that occurred in the DUMP.S7S
folder.

Electromagnetic compatibility of fail-safe modules
Protecting ET 200SP with fail-safe modules against overvoltages
If your equipment requires protection from overvoltage, we recommend that you use an
external protective circuit (surge filter) between the load voltage power supply and the load
voltage input of the BaseUnits to ensure surge immunity for the ET 200SP with fail-safe
modules.
Note
Overvoltage protection measures always require a case
-by-case examination of the entire
plant. Almost complete protection
from overvoltages, however, can only be achieved if the
entire building surroundings have been designed for overvoltage protection. In particular, this
involves structural measures in the building design phase.
For detailed information regarding overvolta
ge protection, we recommend that you contact
your Siemens representative or a company specializing in lightning protection.

Introduction
If you wish to protect the ET 200SP using a ground-fault detector or a residual current circuit
breaker, then you need the leakage resistance to select the correct safety components.
Ohmic resistance
When determining the leakage resistance of the ET 200SP, you must take into account the
ohmic resistance from the RC combination of the module in question:

Formula
You can calculate the leakage resistance of the ET 200SP using the following formula if you
protect all of the modules listed above with one ground-fault detector:

A standard measure for conductors used in the USA, which is assigned to a specific cross-
sectional area of a conductor or wire. Each AWG number represents a jump of 26% in the
cross-sectional area. The thicker the wire, the smaller the AWG number.
BaseUnit
BaseUnits realize the electrical and mechanical connection of the I/O modules with the
interface module and the server module.
The inserted I/O module determines the signals at the terminals of the BaseUnits.
Depending on the selected BaseUnit, only certain terminals are available.
BaseUnit, dark-colored
Conduction of the internal power and AUX buses from the left adjacent module to the
subsequent modules on the right.
BaseUnit, light-colored
Inserted as first BaseUnit and opens a new potential group with electrical isolation. The
power and AUX buses are separate from the adjacent module on the left. It feeds the supply
voltage.
Baud rate
Speed at which data is transferred, indicating the number of transmitted bits per second
(baud rate = bit rate).

defined ends.
BusAdapter
Enables free selection of the connection technology for the PROFINET fieldbus.
Channel fault

In channel-specific passivation, the affected channel is either automatically reintegrated or
the fail-safe module must be removed and reinserted after the fault has been eliminated.
Glossary
Distributed I/O system
314 System Manual, 02/2018, A5E03576849-AH
Channel group
The channels of a module are grouped together in a channel group. Certain parameters in
STEP 7 can only be assigned to channel groups, rather than to individual channels.
Channel number
Channel numbers are used to uniquely identify the inputs and outputs of a module and to
assign channel-specific diagnostic messages.
Channel-specific passivation
With this type of passivation, only the affected channel is passivated in the event of a →
channel fault. In the event of a → module fault, all channels of the → fail-safe module are
passivated.
Configuration
Systematic arrangement of the individual modules.
Configuration control
Function that enables a flexible adjustment of the actual configuration based on a configured
maximum configuration via the user program. Input, output and diagnostics addresses
remain unchanged.
Connecting to common potential
Configuring a new potential group for which a new infeed is set up for the supply voltage.
Connection plug
Physical connection between device and cable.
CPU
The CPU uses the integrated system power supply to supply the electronics of the modules
via the backplane bus. The CPU contains the operating system and executes the user
program. The user program is located on the SIMATIC memory card and is processed in the
work memory of the CPU. The PROFINET interfaces of the CPU establish an Industrial
Ethernet connection. The CPUs of the ET 200SP support operation as an IO controller, I-
device or standalone CPU.
CRC
Cyclic Redundancy Check
Glossary
Distributed I/O system
System Manual, 02/2018, A5E03576849-AH 315
CRC signature
The validity of the process values in the safety frame, the accuracy of the assigned address
references, and the safety-related parameters are validated by means of the CRC signature
in the safety frame.
Crimping
Procedure in which two components, e.g. end sleeve and cable, are connected with each
other by plastic strain.
Dark period
Dark periods occur during shutdown tests and complete bit pattern tests. The fail-safe output
module switches test-related zero signals to the active output. This output is then briefly
disabled (= dark period). An adequate carrier → actuator will not respond to this and will
remain activated.
Derating
Derating allows devices to be used even in harsh operating conditions by selectively
restricting the output capacity. In the case of motor starters, this usually refers to operation at
high ambient temperatures.
Device name
Before an IO device can be addressed by an IO controller, it must have a device name.
An IO device is delivered without a device name. An IO device can only be addressed by the
IO controller after it has been assigned a device name via the PG/PC or via the topology,
e.g. for the transfer of configuration data (such as IP address) during startup or for the
exchange of user data during cyclic operation.
Diagnostics
Monitoring functions for the recognition, localization, classification, display and further
evaluation of errors, faults and alarms. They run automatically during plant operation. This
increases the availability of plants because commissioning times and downtimes are
reduced.

Discrepancy analysis
The discrepancy analysis for equivalence/non-equivalence is used for fail-safe applications
to prevent errors from time differences between two signals for the same function. The
discrepancy analysis is initiated when different levels are detected in two associated input
signals (when testing for non-equivalence: the same levels). A check is performed to
determine whether the difference (for nonequivalence testing: the same levels) has
disappeared after an assignable time period, the so-called discrepancy time. If not, this
means that a discrepancy error exists.
The discrepancy analysis compares the two input signals of the 1oo2 sensor evaluation in
the fail-safe input module.
Discrepancy time
Configurable time for the → discrepancy analysis. If the discrepancy time is set too high, the
fault detection time and → fault reaction time are extended unnecessarily. If the discrepancy
time is set too low, availability is decreased unnecessarily since a discrepancy error is
detected when, in reality, no error exists.

When passivating channels at F-I/O with outputs, the F-system returns fail-safe values (0) to
the fail-safe outputs instead of the output values provided by the safety program.

automatically or only after a user acknowledgment in the safety program.
In the case of a fail-safe input module, the process values pending at the fail-safe inputs are
made available to thesafety program again after reintegration. In the case of a fail-safe
output module, the → fail-safe system transfers the output values in the safety program to the
fail-safe outputs again.

Switch
PROFIBUS is a linear network. The communication nodes are linked by means of a passive
cable - the bus.
By contrast, Industrial Ethernet consists of point-to-point connections: each communication
node is interconnected directly with precisely one other communication node.
If a communication node is linked to several communication nodes, this communication node
is connected to the port of an active network component - the switch. Other communications
devices (including switches) can then be connected to the other ports of the switch. The
connection between a communication node and the switch remains a point-to-point
connection.
The task of a switch is thus to regenerate and distribute received signals. The switch "learns"
the Ethernet address(es) of a connected PROFINET device or additional switches and only
forwards those signals that are intended for the connected PROFINET device or switch.
A switch has a specific number of connections (ports). You connect at most one PROFINET
device or additional switch to each port.
Technology object
A technology object supports you in the configuration and commissioning of a technological
function.
The properties of real objects are represented by the technology objects in the controller.
Real objects can be, for example, controlled systems or drives.
The technology object includes all data of the real object that is required for its open-loop or
closed-loop control, and it signals the status information.

coordination referred to as coordination type "1" and coordination type "2". The short circuit
that needs to be dealt with is cleared reliably and safely with both types of coordination; the
only differences are in the extent of the damage sustained by the device following a short
circuit.
