13
1500H Safety I/O HOLD time exceeded
error Duration of I/O HOLD state exceeded the set
time. • Check that no error occurred on the switching of
systems incorporating SIL2 Process CPUs.
• Check whether an error occurred in communications
with a SIL2 Process CPU.
2002H Output read-back error The discrepancy between an output read-back
value and an output value was detected. • Set "Not used" for "Wiring output selection" of an
unused output terminal.
• Check for a terminal with the error using Output
read-back error detection state (Un\G1536), and
review and adjust connected devices and wiring.

state)
• If the same error occurs again, there may be an
influence from noise or a hardware error. Please
consult your local Mitsubishi representative.
2003H Output dark test error During an output dark test, test pulses were not
detected. • Set "Not used" for "Wiring output selection" of an
unused output terminal.
• Check for a terminal with the error using Output dark
test error detection state (Un\G1540), and review
and adjust connected devices and wiring.

state)
• If the same error occurs again, there may be an
influence from noise or a hardware error. Please
consult your local Mitsubishi representative.
3001H Hardware error A hardware error was detected. There may be an influence from noise or a hardware
error. 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.
3010H External power supply error An error was detected on the external power
supply. • Review and adjust connected devices, wiring, and
voltage.
• 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 possible cause is
a module failure. Please consult your local
Mitsubishi representative.
3020H Safety mutual monitoring error An error was detected in the counterpart device
of mutual monitoring. A moderate error was detected in the counterpart
device of mutual monitoring. Check the error code on
the counterpart device side, and take an action
according to the error code.
3050H Safety parameter error An error of safety parameter was detected at
the startup of the system. The possible cause is a failure of safety parameter
write. Write the safety parameter to the module again
with GX Works3. If the same error occurs again, the
possible cause is a module failure. Please consult
your local Mitsubishi representative.
3060H Module configuration error An error was detected in the module
configuration. • Check that the mounting position of each module is
correct.
• The I/O module with diagnostic functions not
supporting SIL2 mode may be mounted as a pair.
Mount the I/O module that supports SIL2 mode.
• If the same error occurs again, the possible cause is
a module failure. Please consult your local
Mitsubishi representative.
