Error name Description and cause
Hardware error Module hardware error
External power supply The external power supply
OFF error voltage turns off.
Non-volatile memory The IP address and subnet mask
data error (IP stored in the non-volatile memory
address) are abnormal.
IP address setting An IP address setting switch is set
switch out of range to 255.
error
IP address setting An IP address setting switch has
switch changed error been changed with the module
power supply on.
Function setting The function setting switch 1 has
switch 1 changed been changed with the module
error power supply on.
Function setting The function setting switch 2 has
switch 2 changed been changed with the module
error power supply on.
Function setting The function setting switch 3 has
switch 3 changed been changed with the module
error power supply on.
Function setting The function setting switch 4 has
switch 4 changed been changed with the module
error power supply on.
Function setting The function setting switch 5 has
switch 5 changed been changed with the module
error power supply on.
Function setting The function setting switch 6 has
switch 6 changed been changed with the module
error power supply on.
Function setting The function setting switch 7 has
switch 7 changed been changed with the module
error power supply on.
Function setting The function setting switch 8 has
switch 8 changed been changed with the module
error 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.
• 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.
• The module will be automatically recovered immediately
after the error occurs. However, the stored IP address and
subnet mask are lost, and operation is performed
assuming that the following are stored.
IP address: 192.168.3.250
Subnet mask: 255.255.255.0
• Take measures against noise with a shielded cable for
connection.
• If this error occurs again, the possible cause is a module
failure. Please consult your local Mitsubishi representative.
Turn the power on with the IP address setting switch set to a
value in the range 0 to 254.
Return the IP address setting switch to the setting when the
module power supply was 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.
Return the function setting switch 6 to the setting when the
module power supply was on.
Return the function setting switch 7 to the setting when the
module power supply was on.
Return the function setting switch 8 to the setting when the
module power supply was on.
Return the function setting switch 9 to the setting when the
module power supply was on.
