We are running into some issues with serial communications dropping out after a few days. When viewing the PLC hosted web page, we found the following "RX Message Error" count was increasing. Does anyone have information on this error?
Specifically, I'm trying to find out if these errors are indicative of general network issues (noise or frame impacts with messages from other devices on the network) or are specific to network issues with the PLC itself (noise or frame impacts for messages sent to/from the PLC itself).
We have good communications with the PLC for several days at a time, then suddenly the PLC stops responding to requests from the serial master device. If the PLC is power cycled, or the diagnostic counters are reset, comms return to normal (for a few more days).
Thanks for your help!
