4.5 List of Error Codes
Action
No action is required because the system performs a retry. However, if the
error occurs frequently, check for cable failure, hardware failure, noise,
and wiring error.

No action is required because the system performs a retry. However, if the
error occurs frequently, check for cable failure, hardware failure, noise,
and wiring error.
Check for coaxial cable connection and looseness, terminating resistor
connection, and cable failure.
No action is required because the system performs a retry. (Do not switch
the loop in the middle.) However, if the error occurs frequently, check the
line and wiring status.

Check the wiring.
Please consult your local Mitsubishi representative.
Perform the test after the completion of the test from another station.
Eliminate the cause of disconnection and take actions.
• Check for cable failure, hardware failure, wiring error, station number
duplication, control station duplication, and mismatched transmission
speed in the module in the same network.
• If the error occurs again, please consult your local Mitsubishi
representative.

Please consult your local Mitsubishi representative.
Correct the station whose station number is duplicated.
• Retry the test.
• If the error occurs again, the error is the hardware failure of the network
module. Please consult your local Mitsubishi representative.
