Module Error - Mitsubishi Electric MELSEC iQ-F Series User Manual

Module error

Error codes when a module error occurs are classified into major error, moderate error, and minor error, and can be checked
in the [Error Information] tab of the "Module Diagnostics" window of the FX5-ENET. ( Page 97 Module diagnostics) The
error codes are stored in 'Latest error code' (Un\G29).

Error details and causes
Link-down due to disconnection of the
network cable connected to an external
device.
Socket communication send message has
failed.
Data cannot be sent to the external device.
Communication with the external device
was interrupted.
System error or connection connecting error
in OS (Malfunction due to noise or hardware
trouble may have occurred.)
The external device cannot be connected or
is disconnected.
The certificate is set to expire within 90
days.
The number of writes to ROM exceeded
100000. (Number of writes > 100000)
The number of writes to the built-in data
flash exceeded 100000.
IP address change fails.
An error occurred when writing parameters.
The e-mail setting change failed.
The DNS setting change failed.
• The e-mail setting change function was
executed while an e-mail was being sent.
• An e-mail was sent while the e-mail
setting change function was running.
The value set with the e-mail setting change
is outside the range.
The value set with the DNS setting change
is outside the range.
The TLS setting value set with the e-mail
setting change is outside the range.
The certificate tool setting change failed.
Action
• Check the operation of the external device.
• Check if the connection cable is disconnected.
• Check the operation of the external device.
• Check if the connection cable is disconnected.
• Check the operation of the external device.
• Check the conditions of the cables, hubs, and routers on the
lines to the external devices.
• The line may be flooded with packets. Retry after a while.
• The receiving area of the external device may be full (the
window size of TCP is small). Confirm whether the receiving
processing is performed on the external device side or
unnecessary data is not sent from the FX5-ENET.
• Confirm whether the subnet mask pattern and default router IP
address are set correctly on the FX5-ENET and external device
or the IP address class is correct.
• Check the operation of the external device.
• Check the conditions of the cables, hubs, and routers on the
lines to the external devices.
• This error may occur when the connection under communication
is forcibly invalidated. In this case, there is no problem. Re-
connect.
• Check the operation of the external device.
• Check the conditions of the cables, hubs, and routers on the
lines to the external devices.
• This error may occur when the connection under communication
is forcibly invalidated. In this case, there is no problem. Re-
connect.
• Check the operation of the external device.
• Check the conditions of the cables, hubs, and routers on the
lines to the external devices.
• If this error occurs during communication, retry after a while.
Renew the client certificate by the time of expiration.
Replace the module.
Replace the Ethernet module.
Execute the IP address change function again.
If using Certificate Configuration tool for FX5-ENET, write the
server certificate again.
Execute the e-mail setting change function again.
Execute the DNS setting change function again.
• Check that no e-mail is being sent and then execute the function
again.
• Check that the e-mail setting change function is not running and
then send the e-mail again.
Recheck the setting value of the e-mail setting change.
Recheck the setting value of the DNS setting change.
Recheck the TLS setting value of the e-mail setting change.
Execute the certificate tool setting change function again.
