How to fix Mitsubishi Electric FX3U-ENET-ADP when POWER does not turn ON?
If the POWER indicator on your Mitsubishi Electric Controller doesn't light up when you turn on the PLC main unit, start by checking the connection of the Ethernet adapter to the PLC main unit. If the connection is correct, the hardware may be defective, and you should contact your local Mitsubishi Electric representative for repair.
What to do if OPEN does not turn on Mitsubishi Electric Controller?
If the OPEN indicator on your Mitsubishi Electric Controller fails to illuminate, first check the cable connection. If the connection is secure, review the program or parameters. You can also use the diagnosis function of GX Works2 to check error contents.
Why 100M does not turn on Mitsubishi Electric FX3U-ENET-ADP Controller?
If the 100M indicator on your Mitsubishi Electric Controller doesn't turn on, it might be due to using a 10Mbps HUB. Try initial processing or replace it with a 100Mbps HUB. If you are already using a 100Mbps HUB, check the connection of the connectors on both the Ethernet and HUB sides and replace the cable.
What to do if SD/RD LED does not flash when sending and receiving data on Mitsubishi Electric FX3U-ENET-ADP Controller?
If the SD/RD LED on your Mitsubishi Electric Controller isn't flashing during data transfer, first, address any issues causing the [ERR.] LED to light up. Then, verify the cable connection. If the cable is properly connected, use GX Works2 to review the local station IP address, router settings, and subnet mask settings. Finally, examine the sending program of the external device.
Why does ERR. turn on after powering on the Mitsubishi Electric Controller?
If the ERR. light illuminates after powering on your Mitsubishi Electric Controller, it could be due to an Ethernet adapter parameter setting error. Use GX Works2 to check and correct the parameter setting values for the Ethernet adapter. If the parameters are correct, the Ethernet adapter may have a hardware error, and you should contact your local Mitsubishi Electric representative for repair.
