Hello,

This is a question for you Siemens S7-400 Gurus: Is it possible to have Profibus DP redundancy having only ONE S7-414-3 CPU?, this is, having two Profibus Master Modules (CPs) acting one as the backup unit of the other one?

Is this feasible with S7-300, in case it cannot be done with S7-400?

Thanks for your answers.
