● For the central use of the fail-safe ET 200S modules with distributed safety, you require
an IM 151-7 F-CPU or IM 151-8 PN/DP F-CPU.
When using fail-safe ET 200S I/O modules in F-systems, the information contained in the
following manuals applies:
●
ET 200S distributed I/O system
●
Safety Engineering in SIMATIC S7
●
S7 Distributed Safety, Configuring and Programming or S7 F/FH Systems, Configuring
and Programming
F-System with ET 200S
The following figure presents an example configuration for an S7 Distributed Safety F-
system including an ET 200S on PROFIBUS DP/PROFINET IO.
The fail-safe DP master/IO controller exchanges safety-related and non-safety-related data
with the fail-safe and standard ET 200S modules, etc.
