Hello, The following comments may help you despite the discussion on H CPUs.You can find the local shop HERE for more help regarding reparing your faulty CPU.
About the reason of this fault, there are some possibilities.Improper handling of the CPU and ignoring even trivial points for changing batteries may impair its function .Please, pay more attention to warnings in the manual "Automation System S7-400 Hardware and Installation" and try to adhere to all safety recommendations to avoid same cases in future.Also try to communicate with the system in STOP mode and if possible check option of firmware update. I hope these comments help Hamid Hosseini |
