  If the 100M LED turns off on your Mitsubishi Electric Controller, first verify that you are using 100BASE-TX-compliant Ethernet cables. Next, check that the distance between stations is 100m or less. Also, ensure that the Ethernet cables are properly connected. Finally, confirm that a 100BASE-TX-compliant switching hub is in use and that the power supplies for both the switching hub and other stations are turned on.

What does it mean when the ERR. LED flashes on a Mitsubishi Electric Controller?
- D
  David HouseSep 9, 2025
  If the ERR. LED flashes on your Mitsubishi Electric Controller, it means a minor error has occurred. You can determine the cause of the error by checking the CC-Link IE Field Network Basic diagnostic window. You can also identify the error factor by examining the error code within the diagnostic information 2 of the slave station, and then take appropriate action.

What to do if the D LINK LED flashes on a Mitsubishi Electric Controller?
- A
  Ashley TerrySep 6, 2025
  If the D LINK LED flashes on your Mitsubishi Electric Controller, ensure the I/O module's IP address matches the one specified in the master station's configuration settings. Also, in the network configuration, set the reserved station specification of the I/O module to have no setting, and then reflect these changes in the CPU module. Make sure the number of occupied stations of I/O module is set to 1 in the network configuration setting, and reflect the changed parameter in the CPU module. Finally, verify that the I/O module's IP address isn't duplicated by another device.

  If the D LINK LED turns off on your Mitsubishi Electric Controller, several factors could be at play. First, use the CC-Link IE Field Network Basic diagnostic window or the I/O module's LED status to pinpoint the error and then take appropriate steps. Ensure the distance between stations is 100m or less. Check the bending radius of your Ethernet cable against the manufacturer's specifications. Confirm you're using a 100BASE-TX-compliant switching hub and that its power is on. Lastly, make sure the I/O module's IP address isn't conflicting with another device on the network.
