Hello, I am seeking assistance with a customer's CPU experiencing issues with the 24v PSU supply and now displaying an error state. I am unfamiliar with this system, so any guidance would be greatly appreciated. The CPU is showing error codes ER E1 IP 2 with a solid green Run LED, solid green MS LED, and flashing red NS LED. The PLC rack also contains module NX-EIC202 with only the I/O Power LED illuminated in green. Any insights or advice on troubleshooting would be helpful.
If you're seeing Error E1, it may mean that the ethernet link isn't being detected on page 235 of the CJ2 CPU units hardware user manual. IP 2 can help identify the specific port causing the issue. For more information, refer to the manual available for download at the link provided.
According to DarrylR, the error code E1 signifies that the "ethernet link is not detected" on page 235 of the CJ2 CPU Units Hardware User's Manual. IP 2 may identify the specific port in question.
