CHMI 5.1 stopped updating the value and any operation
Help me please.
End user informed me that the CHMI 5.1 suddenly
stopped updating the values and accepting any operation. I completely formated the computer twice and reinstalled all software, and tried to communicate. I could browse tags but values updates very very slowly.
Message occurs "In the PLC configuration, the communication module was not configured correctly or not at all", while it was showing some error in CPU Diagnostics PMxx eth...
Remedy: Adapt PLC Configuration

And this plant was running from last one year, and Existed the PLC Hardware is
PM573-ETH, With 9 mix modules all are working, on IO bus.
I feel that it would be better to troubleshoot from PM573 side first. As per the error, there may be some issue with the CM577/597 ethernet coupler or the onboard ethernet port.
1) Try to do a warm restart of the controller
2) Perform symbol file configuration and download the program
3) Recreate configuration from automation builder and download the program onto the PLC (Assuming you have latest backup) if no resolution even after steps 1 to 2
