Error name Description and cause
Non-volatile memory An error of the parameter data
data error (parameter) stored in the non-volatile memory
has been detected.
Output read-back A discrepancy of an output read-
error back value and an output value
was detected.
Output dark test error During an output dark test, test
pulses were not detected.
I/O data error An error was detected by the input
diagnostic.
Module power supply A module power supply error was
voltage error detected.
Remote buffer An area outside the range of the
memory access error remote buffer memory areas has
been accessed using a dedicated
instruction.
IP address switch An IP address setting switch has
changed error been changed with the module
power supply on.
Action
• Restart the safety remote I/O module. The parameters
are initialized and the module is recovered. In such a
case, parameters are required to be set again by
users.
• If the same error occurs again, the module may be in
failure. Please consult your local Mitsubishi
representative.
• Review the connected devices and wiring.
• Check that 24V is supplied to the external power
supply using a tester.
• Check that the external connection is not overloaded.
• When the connected devices and wiring have no
errors, there may be an influence from noise or a
hardware failure. Take measures to reduce noise.
• Power on the external 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 and wiring.
• Check that 24V is supplied to the external power
supply using a tester.
• Check that the external connection is not overloaded.
• Correct the parameter settings of "Output dark test
pulse OFF time setting " Yn and "Number of pulse
output for output dark test".
• When the connected devices and wiring have no
errors, there may be an influence from noise or a
hardware failure. Take measures to reduce noise.
• Power on the external 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 and wiring.
• When the connected devices and wiring have no
errors, there may be an influence from noise or a
hardware failure. Take measures to reduce noise.
• Power on the external 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.
• 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.
• Correct the setting data of the dedicated instruction to
access within the range of remote buffer memory
areas.
The module will recover from this error by setting the
switches to the previous IP address that was set when
the module power supply was powered on.
