Hello, I have a S7 1215C with couple of DI, DO, AI ,AO modules. Reference picture of hardware is attached. I am getting message in Diagnostic buffer "New I/O access error during process image update" though allmodules are displayed green in online hardware view. PLC starts to malfunction after that. It went to stop mode after sometime. After power restart, PLC again works for another 30 minutes and then the same fault pops up in the diagnostic buffer. Can you help me to solve it?

Hello, Did you try to compile (Rebuild All) and download hardware to CPU. Best regards, Wizard |

hi, I guess there is something disturbing the backplanbus. I would try to change the order of the modules, to look what happens then. Maybe an FW-Update could help there. The newest FW can be downloaded here: Firmware update for CPU 1215C, DC/DC/DC, 14DI/10DO/2AI/2AO Firmware update for CPU 1215C, DC/DC/RLY, 14DI/10DO/2AI/2AO Firmware update for CPU 1215C, AC/DC/RLY, 14DI/10DO/2AI/2AO hope this helps, regards, |
