Error name Description and cause
Hardware error Module hardware error
RWw/RWr setting error When "Network Synchronous
Communication" in the network
configuration settings is set to
"Synchronous", System area
(RWw3/RWr3) is not set in "RWw/
RWr Setting".
Synchronization cycle The synchronization cycle set in
setting error the master station is not
supported by the I/O module.
Synchronous Synchronous communication with
communication error 1 the master station has failed for a
certain period of time.
Synchronous Synchronous communication with
communication error 2 the master station has failed for a
certain period of time.
External power supply The external power supply voltage
OFF error turns off.
IP address/station The IP address/station number
number setting switch setting switches are set outside
out of range error the range of 1 to 120.
MODE switch incorrect The MODE switch is set to an
incorrect state.
IP address/station An IP address/station number
number setting switch setting switch has been changed
changed error with the module power supply on.
Function setting switch The function setting switch 1 has
1 changed error been changed with the module
power supply on.
Function setting switch The function setting switch 2 has
2 changed error been changed with the module
power supply on.
Function setting switch The function setting switch 3 has
3 changed error been changed with the module
power supply on.
Function setting switch The function setting switch 4 has
4 changed error been changed with the module
power supply on.
Function setting switch The function setting switch 5 has
5 changed error been changed with the module
power supply on.
Description
An error that cannot be recovered. The RUN LED turns off.
An error where the module cannot continue to operate. The ERR. LED turns on.
An error where the module can continue to operate. The ERR. LED flashes.
Action
Power off and on the module power supply.
If this error occurs again, the possible cause is a module
failure. Please consult your local Mitsubishi representative.
Correct the RWw/RWr setting of the network configuration
setting to assign the System area (RWw3/RWr3), and turn
off and on the module power supply or perform remote
reset.
Check the synchronization cycle of the master station, and
then turn off and on the power supply of the I/O module or
perform remote reset.
Take any of the following actions, and then turn off and on
the power supply of the I/O module or perform remote reset.
• For the synchronization cycle setting for the master
station, set a long cycle.
• Reduce the number of slave stations operating with the
CC-Link IE Field Network synchronous communication
function.
• Take measures against noise on the transmission path.
Take measures against noise on the transmission path, and
then turn off and on the module power supply of I/O module,
or perform remote reset.
• Check the state of the external power supply.
• Check if the power supply voltage satisfies the
specifications for the I/O module.
• Correct the timing of turning on or off External power
supply monitor request (RWw2.b9) if an error occurs
when starting or stopping the system.
Turn on the power supply with the IP address/station
number setting switches set to a value in the range 1 to 120.
Set the MODE switch correctly.
Return the IP address/station number setting switch to the
setting it had when the module was powered on.
Return the function setting switch 1 to the setting when the
module power supply was on.
Return the function setting switch 2 to the setting when the
module power supply was on.
Return the function setting switch 3 to the setting when the
module power supply was on.
Return the function setting switch 4 to the setting when the
module power supply was on.
Return the function setting switch 5 to the setting when the
module power supply was on.
