AF100 communication with redundant AC800M
In our project we want to replace AC450 Controller with Redundant AC800M and use the existing AF100 network to communicate with Remote IO cards and also we want to connect existing AC160 Controller to redundant AC800M. the current network layout is attached.we need to know,how to do these and how connect remote io and AC160 to redundant AC800M.Can somebody help us.

The CI869 card on the AC800M controller cannot act as bus master. Only slave. So you can not connect S800 IO to AC800M via AF100. You have to shift to another bus like profibus by changing all CI810's to CI801. If you can remain a bus master module on the existing AF100 bus then AC800M with CI869 can continue to communicate with other nodes on the bus like AC160 controller by using send receive DSP. For more details please refer to below AF100 document below.
