F-System with ET 200pro
The following figure presents an example configuration for an S7 Distributed Safety F-
system including an ET 200pro on PROFIBUS DP/PROFINET IO.
The fail-safe DP master/IO controller exchanges safety-relevant and non-safety-relevant
data, for example, with the fail-safe and standard ET 200pro modules.
