Error Code List

Error codes related to the safety remote I/O module

Errors of the safety remote I/O module are classified into the following three types.
*1
Error status Description
Major error Error because of which the module stops, such as hardware failure. The safety functions (safety I/O, safety diagnostics, and safety
communications) stop.
Moderate error Error because of which the module stops, such as a parameter error related to module operation. The safety functions (safety I/O, safety
diagnostics, and safety communications) stop.
Minor error Error after which the module continues its operation, such as double input discrepancy detection. The safety functions keep operating.
*1 When multiple errors have occurred, the error statuses are displayed in the order of error severity (Major error > Moderate error > Minor
error).

Error name Description and cause
Hardware failure A hardware failure was
detected.
Self-diagnostic error An error was detected by the
self-diagnostics.
Overload error Overcurrent was detected in
the input power supply or
output power supply.
Power supply voltage An error was detected in the
error module power supply or load
power supply.
Date out of range error Incorrect clock data was
received from the CPU module.
Restart not performed The module has not been
after safety module restarted after the safety
validation module validation.
Safety module validation The safety module validation
not performed has not been performed.
Action
Set the operating ambient temperature within the range
of general specifications. If the operating ambient
temperature is within the range of general
specifications, there may be an influence from noise or
a hardware failure. If the same error occurs again even
after measures have been taken against noise, the
module may be in failure. Please consult your local
Mitsubishi representative.
• Review the connected devices, wiring, and voltage.
• Power on the load power supply at the same timing of
power-on of the module power supply.
• If the same error occurs again, the module may be in
failure. Please consult your local Mitsubishi
representative.
• Review the connected devices, wiring, and voltage.
• Power on the load power supply at the same timing of
power-on of the module power supply.
• There may be an influence from noise of external
wiring (such as power supply part and I/O signal part).
Review the connected devices and wiring.
• If the same error occurs again, the module may be in
failure. Please consult your local Mitsubishi
representative.
There may be an influence from noise or a hardware
failure. If the same error occurs again even after
measures have been taken against noise, the module
may be in failure. Please consult your local Mitsubishi
representative.
• Restart the safety remote I/O module. After the safety
remote I/O module validation, safety communications
can be established by restarting the module.
• If the same error occurs again even after the safety
remote I/O module has been restarted in no error
state, the module may be in failure. Please consult
your local Mitsubishi representative.
• Perform the safety module validation. After the safety
module validation, safety communications can be
established by restarting the module.
• If the same error occurs again even after "Safety
module validation" is executed in no error state, the
module may be in failure. Please consult your local
Mitsubishi representative.
