From my customer:
I am using a Mitsubishi FX3U processor with an Ethernet adapter card. I’m getting communication errors when trying to read tags. In the EWON I am using the MELSEC I/O server and getting communication errors.
Backups moved to staff note
His IO Server config looks to be the same as the last reply in this thread: Mitsubishi FX3 to eWon flexy
But I don’t have a Mitsubishi PLC to test with unfortunately.
Edit: He’s going through an N-Tron switch from Flexy to PLC
