System Architecture of ABB Redundant CPU

The Following System Architecture illustrates a physical connection of two redundant

CPU(ABB PM-573 ETH) where data visual is provided by ABB HMI. The data transfer is using ethernet cable.This particular HMI has a facility of SWAP IP Configuration as well which connects to other CPU if one of them Fails to provide data, between both the CPU data is synchronized via the cross cable and the Coupler connected together with the CPU provides data updation to LAN where the HMI updates the data from.The Following IP provided is just for illustration,other IP can also be used.
