vermasaket Posts: 1 Rating: (0)	I have a sinlge rack UR1 with two CPU (S7-400). My question is that whether we can give the same I/O address to the input module in different CPU. When i am trying to do it is saying that the address is using above please choose different address. Please suggest whether we can do it or we have to give different addresses in both the CPU.
