Hello alls.
I have a question related to plc cpu 414-4H redundant system.
The qestion is : at the same time only one CPU could be in run mode, and the other one is at stop mode. There is no possibility to run both of them simulatounsly. We have just changed the cables between CPU. But i does not work. Would please tell me how could we solve this problem?
