‚ÄčNote that these messages may also indicate that you configured the CODESYS OPC UA  device with the wrong address. Double check that your configuration details are correct, and, if possible, try using another OPC UA client to verify the address.

To re-establish communication to the CODESYS OPC UA server, restart the GRV-EPIC-PR1.
