Error name Description and cause
Safety module The safety module validation
validation failure failed.
Safety module The safety module validation
validation not has not been performed.
performed
Non-volatile An error of the module
memory data error operation information stored in
(module operation a non-volatile memory has
information) been detected.
External power An external power supply
supply voltage error error was detected.
Parameter data A value with an error or
error parameter data out of the
range is set.
Parameter data The version mismatch of the
error (version module used and engineering
information) tool was detected.
Parameter data A value with an error or
error (wiring parameter (wiring selection of
selection of input) input) out of the range is set.
Parameter data A value with an error or
error (input parameter data out of the
response time) range is set.
Parameter data A value with an error or
error (input dark test parameter (input dark test
execution setting) execution setting) out of the
range is set.
Action
• Check that no error other than "Safety module validation
failure" has occurred on the module using the ERR. LED of
the module and error history. If an error has occurred,
eliminate the cause.
• 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.
• Perform the safety module validation and restart the
module.
• If the same error occurs again, the module may be in
failure. Please consult your local Mitsubishi representative.
• The module will automatically recover immediately after the
error occurs. Note that number of ON times integration
value will be initialized to zero.
• If the same error occurs again, the module may be in
failure. Please consult your local Mitsubishi representative.
• Match the ON timing of the external power supply with the
ON timing of the module power supply.
• Review the connected devices, wiring, and voltage.
• There may be an influence from noise of external wiring
(such as power supply part and I/O signal part). Take
measures to reduce noise.
• If the same error occurs again, the module may be in
failure. Please consult your local Mitsubishi representative.
• Correct the module parameter setting and module
configuration.
• When the parameters are set again and the parameter
setting has succeeded, the module will recover from this
error.
• Review the version of the engineering tool and that of the
master station.
• Check that the module version set in the "Network
Configuration Settings" of the engineering tool matches
with the version of actual module.
• When the parameter is set again and the parameter setting
has succeeded, the module will recover from this error.
• Correct the module parameter settings (wiring selection of
input) and module configuration.
• When "Wiring selection of input" Xn (n: even number) is set
to "1: Double wiring (NC/NC)", set the same value for Xn+1.
• When the parameters are set again and the parameter
setting has succeeded, the module will recover from this
error.
• Correct the module parameter settings (input response
time) and module configuration.
• When "Wiring selection of input" Xn (n: even number) is set
to "1: Double wiring (NC/NC)", set the same value for Xn+1.
• Set the input response time so that it is longer than the
input dark test pulse output time.
Input dark test pulse output time = Pulse OFF time for the
input dark test  ((Number of pulse outputs for the input dark
test  2) - 1)
• When the parameters are set again and the parameter
setting has succeeded, the module will recover from this
error.
• Correct the module parameter settings (input dark test
execution setting) and module configuration.
• When "Wiring selection of input" Xn (n: even number) is set
to "1: Double wiring (NC/NC)", set the same value for Xn+1.
• When the parameters are set again and the parameter
setting has succeeded, the module will recover from this
error.
