4.7 Error Codes
Error details and cause
• A momentary power failure has
occurred.
• The power supply has been shut off.
Power has been shut off or the power
supply voltage has dropped in either of
the redundant power supply modules on
the redundant power supply base unit.
Or, only one redundant power supply
module is mounted.
A failure has been detected in either of
the redundant power supply modules on
the redundant power supply base unit.
An invalid power supply module has
been mounted on the redundant power
supply base unit.
A power supply module other than the
redundant power supply module has
been mounted on the redundant power
supply base unit.
The number of writes to the flash ROM
(data memory and system memory) has
exceeded 100000.
(Number of writes > 100000 times)
A moderate error has been notified from
the intelligent function module
connected.
An inter-module synchronous signal
error has been notified from the
intelligent function module connected.
Number of reception requests of
transient transmission exceeded upper
limit of simultaneously processable
requests.
Transient reception failed.
Too much transient transmission
processing exists and transient
transmission cannot be performed.
A CC-Link IE Field Network error has
occurred.
Action
Check the power supply status.
• Check the power supplied to the power supply
modules on the base unit.
• Check that two power supply modules are
mounted on the base unit. If the same error
code is displayed again, the possible cause is a
hardware failure of the power supply module.
Please consult your local Mitsubishi
representative.
The possible cause is a hardware failure of the
power supply module. Please consult your local
Mitsubishi representative.
Mount only applicable power supply modules.
If the same error code is displayed again, the
possible cause is a hardware failure of the power
supply module. Please consult your local
Mitsubishi representative.
Mount only applicable power supply modules.
If the same error code is displayed again, the
possible cause is a hardware failure of the power
supply module. Please consult your local
Mitsubishi representative.
Replace the remote head module.
Check the detailed information (system
configuration information) of the error by executing
module diagnostics using the engineering tool,
identify the error module, and eliminate the error
cause.
Check the detailed information (system
configuration information) of the error by executing
module diagnostics using the engineering tool,
identify the error module, and eliminate the error
cause.
Lower the transient transmission usage frequency,
and then perform again.
Lower the transient transmission usage frequency,
and then perform again.
Correct the number of transient transmissions
executions.
Check the details of the error by executing the CC-
Link IE Field Network diagnostics, and take action
according to the action for the relevant error.
