Hi,
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.
If possible,
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
4) Check the following link
