Good morning World, Before being suspicious on any components of your SIMATIC S7-400 automation system,Please read more about grounding in chapter 4 and notes in A.2 in the following manual:
Automation System S7-400 Hardware and Installation and if there is no problem in installation and improper handling of modules by maintenance personnel,I suggest checking possible faulty CPU (components) in a workshop with standard/test situation.Change faulty components with new one and ask HELP FROM HERE , if CPU has a persisting problem. I hope this helps you Hamid Hosseini |
