Troubleshooting - Mitsubishi Electric AJ65BT-RPI-10A User Manual

6. TROUBLESHOOTING

Any error during data link can be checked by the ERR. LED of the
master station.
If the ERR. LED of the master station is lit or flickers due to a data link
error, first refer to the user's manual of the master module used and
check the data link states of the other stations in the CC-Link system.
If there are many stations in data link error on the downstream side of
the AJ65BT-RPI-10A/10B (the side on which the master station does
not exist), the AJ65BT-RPI-10A/10B may be faulty. Therefore, make a
line test again (refer to Section 4.7).
