Hello, I hope you have a backup of software. Remove the EPROM card and try to load the software. If CPU's behavior is the same you can try with firmware update.Where do you find the latest updates of the operating systems of S7-400 CPUs? If this also dosn't help, you should replace the CPU with new one and send it for repairing. Best regards, Hristo MIhalev |
