2.1 What is the SIMATIC ET 200SP distributed I/O system?

Thanks to its multifunctionality, the SIMATIC ET 200SP distributed I/O system is suitable for
a wide range of applications. Its scalable design allows you to tailor your configuration to
local requirements. Different CPUs/interface modules are available for connection to
PROFINET IO or PROFIBUS DP.

SIMATIC ET 200SP with CPU allows intelligent pre-processing to relieve the higher-level
controller. The CPU can also be used as standalone device.

By using fail-safe CPUs, you can implement applications for safety engineering.
Configuration and programming of your safety program takes place the same way as for
standard CPUs.

A wide range of I/O modules rounds off the product range.

SIMATIC ET 200SP is designed with degree of protection IP20 and is intended for
installation in a control cabinet.

The SIMATIC ET 200SP distributed I/O system is installed on a mounting rail. It consists of:

● CPU/interface module

● Up to 64 I/O modules, which can be plugged into BaseUnits in any combination

● Up to 31 motor starters

● A server module that completes the configuration of the ET 200SP.

Area of application of ET 200SP with fail-safe I/O modules

2.2 What are fail-safe automation systems and fail-safe modules?

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 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.

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 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.

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.

2.3 How are SIMATIC Safety F-systems structured 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 2-3 Fail-safe SIMATIC Safety automation system (sample configuration)

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.

Fail-safe motor starters are suitable for safety-related tripping of motor loads.

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

Requirements

3.4 Forming potential groups

Potential groups for the ET 200SP distributed I/O system are formed by systematically
arranging the BaseUnits.

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 and AUX bus 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 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

WARNING

Hazardous Voltage
Can Cause Death, Serious Injury, or Property Damage.

3.4 Forming potential groups

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.

Do not connect any BaseUnit of the "BU...B" type on the right of a motor starter's BaseUnit
(BU30-MSxx).

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.

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.

3.4 Forming potential groups

BaseUnits with additional AUX terminals (e.g. BU15-P16+

+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 BaseUnits of motor starters, the AUX bus is interrupted to the left. An internal
24 V DC signal is output to the right.

The AUX bus can be used individually:

● As a protective conductor bar (the requirements of EN 60998-1 apply). To comply with

this standard, a maximum of 8 I/O modules may be plugged into the corresponding
potential group.

● For additionally required voltage

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))

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.

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

3.4 Forming potential groups

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.

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.

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: 3RK1908­1DA00-2BP0).

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).

4.2 Installation conditions for motor starters

Observe the following installation conditions when using an ET 200SP motor starter:

● Mounting position
You can install the motor starter vertically, horizontally or on its back. 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 and recumbent mounting position

Also take into account 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

Rules and regulations for operation

Introduction

Specific application

EMERGENCY STOP devices

Excluding hazardous plant states

Line voltage

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.

Adhere to the safety and accident prevention regulations applying to specific applications, for
example machine protection guidelines.

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.

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!

An uncontrolled or undefined startup must not occur after the EMERGENCY STOP is
unlocked.

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 281)):

● 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.

Protection against outside electrical influences

Reference

5.1 Rules and regulations for operation

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 286)).

● For 24 V DC supply: Ensure safe (electrical) isolation and separate cable laying or
increased insulation of the extra-low voltage (SELV/PELV) to circuits with hazardous
potentials in accordance with IEC 60364-4-41.

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
protective conductor with 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.

Safety extra low voltage for fail-safe modules and fail-safe motor starters

WARNING

WARNING

5.2 Additional rules and regulations for the operation of the ET 200SP with fail-safe modules

The fail-safe modules must be operated with safety extra low voltage (SELV, PELV).

You can find more information on safety extra-low voltage in the data sheets, for example,
of the applicable power supplies.

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 U

= 36 V DC even in the event of a fault.

m

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 as
well. The process signal of a 24 V DC digital module may not exceed a fault voltage U

in

m

the event of a fault.

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 U

to be exceeded.

WARNING

Reliable detection by F-modules with inputs

5.2 Additional rules and regulations for the operation of the ET 200SP with fail-safe modules

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.

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).

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.

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.

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 F­module.

The maximum permitted switching frequency of the sensor signals results from the minimum
duration.

Additional requirements for actuators

WARNING

Technical specifications of sensors and actuators

5.2 Additional rules and regulations for the operation of the ET 200SP with fail-safe modules

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.

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.

Refer to the manuals of the fail-safe modules for technical specifications to assist you in
selecting sensors and actuators.

5.3 Additional rules and instructions for operation with motor starters

When fail-safe digital output and input signals are in a single cable, F-DQ modules and F­PM-E modules may experience readback errors.

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.

● Separate cables for F-DI modules, F-DQ modules, and F-PM-E modules or non-fail-safe

● 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.

Note that an inductive load connected to the F-DQ channels can induce coupling of a strong
magnetic field.

● Separate the inductive loads spatially or shield against the magnetic field.

● Configure the readback time to 50 ms or higher.

Operating the ET 200SP on grounded incoming supply

Introduction

Grounded incoming supply

Safe electrical isolation (SELV/PELV in accordance with IEC 60364-4-41)

Configuration of ET 200SP with ungrounded reference potential

5.4 Operating the ET 200SP on grounded incoming supply

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.

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.

Load current / power supply modules with safe electrical isolation are required for the
operation of the ET 200SP distributed I/O system. According to IEC 60364-4-41, 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.

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 (protective
conductor).

● 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
