hexe Posts: 1 Rating: (0)	Hi! we are having a problem with our redundancy system; is an 414-4H system, and due to a programming error the standby CPU went to stop mode. When we try to start it we get this error message: "This action is not permitted in the current mode of the module"; we tried to stop the whole system and restart everything again, and even reset the memory, but still won't go. Any ideas? Thanks Hexe
