Issue

After configuring an NOE Ip address in the M340 project and properly linking it in the software and transferring, I see a solid ERR on the NOE module.

Product Line

Modicon M340, Control Expert, Unity Pro

Resolution

If the M340 and NOE Run are both on solid and the NOE still has a solid ERR light the most common cause is not cable.

No cable would be accompanied by ETH STS exhibiting 3 flashes.

See below the NOE indicator meanings.
