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-relevant and non-safety-relevant
data with the fail-safe and standard ET 200S modules, etc.
