High availability with fail safe modules
We have 2 PM595 CPUs (AC500) and some non-safety and safety I/O modules. Is it possible to have redundancy using CI502-PNIO (Profinet Interface Module) for remote expansion of safety modules?

We cannot have CPU redundancy with Safety processors , I/O at the moment in the AC500-S system. Please note that the SIL3 configuration itself has redundant CPUs, and I/O modules with redundancy/error checking with in the system - with 1oo2 -SIL3 qualification. This would suffice most requirements which ask for 1oo2 safety.
