Use of the module
The F-CM AS-i Safety ST module is a communication module for use in the
SIMATIC ET 200SP Distributed I/O System.
The F-CM AS-i Safety ST module features a 20 mm wide ET 200SP module housing. A
BaseUnit (BU) is required for use in the ET 200SP. The F-CM AS-i Safety ST module can be
plugged in to:
●BaseUnit Type C0
●BaseUnit Type C1
The F-CM AS-i Safety ST fail-safe communication module expands a standard AS-Interface
network to include safety-related communication.
The F-CM AS-i Safety ST module reads the input states of safety-related AS-Interface input
modules and provides these states to a fail-safe F-CPU for further evaluation.
In the opposite direction, the F-CM AS-i Safety ST module receives safe output states of an
F-CPU and outputs them for control of safety-related outputs on AS-Interface.

Product overview
3.1 Properties of the F-CM AS-i Safety ST
Fail-safe Module F‑CM AS‑i Safety ST (3RK7136‑6SC00‑0BC1)
14 Manual, 03/2017, A5E03957059020A/RS-AB/002
The F-CM AS-i Safety ST fail-safe module supports safety-related applications up to SIL 3
according to EN 62061 or safety category up to PL e according to EN 13849-1. The input
and output values of the safety-related AS-i slaves are addressed using the safe cyclic
process image. You need an F-CPU for safe processing.
The F-CM AS-i Safety ST module has no AS-i master functionality. For operation of the AS-
i network, you need a CM AS-i Master ST module (3RK7137-6SA00-0BC1) or another
AS-i master conforming to AS-i Specification V3.0.
You can plug several F-CM AS-i Safety ST modules into one SIMATIC ET 200SP station. An
F-CM AS-i Safety ST occupies 16 input bytes and 8 output bytes in the I/O address space.
The number of F-CM AS-i Safety ST modules that can be plugged in depends on:
●The maximum address space of the utilized interface module (IM) of the ET 200SP
●The amount of address space occupied by other modules
Up to five module combinations of CM AS-i Master ST (32 input bytes/32 output bytes) and
F-CM AS-i Safety ST (16 input bytes/8 output bytes) can be plugged in to one SIMATIC
ET 200SP station with standard interface module IM 155-6 PN ST having a maximum
address space of 256 input bytes/256 output bytes. If other modules are present in the
ET 200SP station, the available address space and the maximum number of AS-i modules
are reduced.
In a SIMATIC ET 200SP station with High Feature Interface Module IM 155-6 PN HF and a
maximum address space of 1 440 input bytes/1 440 output bytes, a correspondingly greater
number of modules can be plugged in.
You can find additional information in ET 200SP System Manual
(http://support.automation.siemens.com/WW/view/en/58649293/0/en).

Accessories
The following components can be used with the module:
●Labeling strips
●Reference identification label
Ease of maintenance
The following features support maintenance:
●Code sequences are saved in the coding element. As a result, teaching of the code
sequences does not have to be repeated after an F-CM AS-i Safety ST module is
replaced.
●Use is automated to the greatest extent possible. This applies, in particular, to the
teaching of the code sequences of safe AS-i slaves.
●An F-address that has already been assigned is stored in the coding element. This
means that there is no need to repeat teaching-in after replacing the
F-CM AS-i Safety ST module.
●The module/BaseUnit concept allows you to easily replace defective hardware. Remove
the defective module from the rack and plug in the new module.
Further information can be found in the Section "Code sequences (Page 75)".
Certifications
More detailed information regarding certifications can be found in the ET 200SP System
Manual (http://support.automation.siemens.com/WW/view/en/58649293/0/en).
3.2
Operating modes of the F-CM AS-i Safety ST
3.2.1
Standard mode
Self test during device startup
After the AS-i voltage is switched on (PWR LED shows steady green light), the F-CM AS-i
Safety ST module performs a comprehensive self-test. During this test, all LEDs are lit for
approximately 3 seconds. Exception: the "DIAG" LED is controlled directly by the ET 200SP
backplane bus and indicates the communication status for the ET 200SP system.
Checking of the F-address
After the self-test, the module checks the F-address. If no valid F-address is available, the
"DIAG" and "PROFIsafe" LEDs flash red (the status LED flashes green). You must then
assign the F-address, see Section "F-parameters (Page 44).

Manual, 03/2017, A5E03957059020A/RS-AB/002 17
Downloading of the module parameters
The F-CM AS-i Safety ST then begins to read in code sequences of the safe AS-i slaves on
the connected AS-i bus. At the same time, the module downloads the module parameters
that were stored in the PLC CPU. The module parameters can only be downloaded when the
operating voltage is applied to the interface module of the ET 200SP and the parameters
have been made available by the PLC CPU during startup of the ET 200SP station.
The "Status" LED flashes green until the module parameters are completely downloaded or
the PLC CPU is in STOP state, or the PLC communication is interrupted.
Cyclic data exchange of safe input/output data
When a valid set of module parameters has been downloaded and the PLC CPU is in "RUN"
state, the safe input/output data is evaluated according the parameter assignment and
exchanged with the PLC CPU.
The PROFIsafe protocol is used for the data exchange.
The "Status" LED is lit green during cyclic data exchange.
If the F-CM AS-i Safety ST module starts cyclic data exchange directly after startup, but
communication cannot yet be established on the AS-i bus, the F-CM AS-i Safety ST module
supplies the substitute value "0" in the input image. Passivation is delayed by a maximum of
30 s in this case. As a result, communication can start on the AS-i bus within this time
window without passivation. After this time window, the input/output channels are passivated
if there is no AS-i communication.
3.2.2
Error statuses
Note
Statuses not considered to be errors
The F
-CM AS-i Safety ST module does not consider the following statuses to be errors, i.e.
no alarm and no passivation is triggered:
•
Waiting for start-up test
•
Input/output with value = 0 in the process image without error condition, e.g. normal
opening of the input contacts by pressing an emergency stop button or opening a
protective door.
Diagnostic information can be read out in the user program using data records. For
information, please refer to Section "
Data records for diagnostics (Page 57)".

In the event of a serious device fault, communication with the F-CM AS-i Safety ST module,
e.g., reading a data record, is not possible. The substitute value "0" is processed for inputs
and outputs, and all channels are passivated.
1. Switch off the module.
2. Wait for the module to cool down, if necessary.
3. Switch on the device again.
4. If the error persists after the module is switched on, the module must be replaced.

Device fault
Description
Examples of conditions that trigger a device fault are:
●Device fault (e.g. sporadic synchronization error, see also DS92)
●Configuration error (e.g. problem with contact to backplane bus, coding plug missing, see
also DS92)
You can read the following pattern on the LEDs:

In the event of a device fault of this type, communication with the F-CM AS-i Safety ST
module is only possible. e.g., for reading out additional diagnostic information via data
records. The substitute value "0" is processed for inputs and outputs, and all channels are
passivated.
●Make sure that the station is properly grounded.
●Check whether the coding element is present or replace it if necessary.
●Plug the module into the BaseUnit in an untwisted position.
Switch off the module. If the error persists after the module is switched on and no external
error cause can be found, the module must be replaced.

Process signal error
Description
Examples of conditions that trigger a process signal error are:
●Discrepancy error at the inputs of a safe AS-i input slave
●Sequence error at the inputs of a safe AS-i input slave
●Sporadic code sequence error (from FW V1.0.1), e.g. fault caused by EMC in the input
circuit
●Code sequence error at a safe AS-i input slave, e.g. due to cross-circuit at the inputs
●Failure of a safe AS-i input slave
You can read the following pattern on the LEDs:
