Hello Osld;

That is because the IM 153-2 is transparent to the F-configuration.

The selected IM model must support Safety over Profibus, but once that is certified than it is the F-IO modules that must be configured and parameterized properly so they exchange F-data with the F-CPU.

See the following screenshot. showing how an example of the F-parameters for an  F-DI module on a ET 200M (notice that there is nothing special to the configuration of the IM 153-2 in this example).

SIMATIC Safety Integrated for Process Automation Wiring and Evaluation Architectures for Failsafe Digital Input (F-DI)- and Output-Modules (F-DO) of ET 200M

Hello Olivier;

Although I cannot find a certification document from TUV that specifically certifies an ET 200M station (with an IM 153-2 communications head) for Profisafe applications, see  here for example:

Where can you find the TÜV certificates relevant for SIMATIC S7 F/FH systems?

I have found some sources that may help you out.

First, from Siemens:

• Technical description, Et 200M

• Profisafe System Description

9.1. Remote I/O

Standard remote I/O now are able to incorporate safety modules without changing the head stations. F-Modules such as digital input/output, analog input/output, power modules, motor starters, and frequency converters with integrated safety are available. The F-Modules can be grouped together and allow shut-down in groups.

And from Profibus.com (Profibus International: Profisafe Profile products):
