See what i saw from your configuration is that 1. you have connected two cpu PN port with each other. 2. you have taken one set of PN port to Scalance switch and given to IE to PB converter. But where does the ring come to picture. Instead of that you can use the PB port to connect directly to ET200 M station. or in case ET200 M PN port IM .

NO (sorry). Put simple, the IE PB link does NOT support so called Profinet "System Redundancy" (only the IM 153-4 does support this at the time of writing). System Redundancy means that the IO Device is capable of having a communication relationship with both H-CPU's. Without this, you can only use the IE PB as unilateralI/O" (i.e. the IO devicebelongs to only one of your H CPU''s). Have a look at Configuration Examples for S7-400H with PROFINET SIMATIC S7-400H as of V6.0 for more on what can and can not be done as far as System Redundancyis concerned. Please note though that MRP can be used with H-Systems too, but is a totally seperate thing to System Redundancy (in other words, just because you can have the IE PB link connected to an MRP ring via a switch and it is physically reachable by both H CPU'sdoes NOT mean it is capable of having a logical IO device related connection to both H CPU's). I hope this helps
