How to configure two diffrent profibus slaves with same data, to work as redundant slaves in AC800M
I need to configure two Profibus links from a Siemens PLC as a redundant Profibus link to CI854 card. The Frist Profibus link is connected to CPU314C-2 DP Port X2 DP and next link is from card CP341 in Siemens PLC. Both links are sending identical data, but both links have different slave IDs and different GSD file(Two Independent slaves with identical data). So it's not possible to configure redundancy in hardware level. Please advise the best way to achieve redundancy in this case.

Since you are not looking at redundancy in hardware level, you should configure watchdog counter from both the communication independantly,receive at AC800M side & then switch between them(to the healthy one,when one goes faulty) to achieve redundancy in your application software.
