10.6 List of Error Codes
Error details and causes
An error is detected while an e-mail is being
sent.
A value in 'MQTT connection setting'
(Un\G108808 to Un\G108823) is outside the
range.
'Tool setting storage area write request'
(Un\G108872) and 'Tool setting storage
area clear request' (Un\G108874) turned
from off to on simultaneously.
A value in 'Tool setting' (Un\G108879 to
Un\G108895) is outside the range.
'Tool setting storage area write request'
(Un\G108872) and 'Tool setting storage
area clear request' (Un\G108874) turned
from off to on simultaneously.
An instruction other than executable
dedicated instruction numbers has been
specified.
The dedicated instruction request data from
the CPU module was discarded because
the data size was abnormal.
The dedicated instruction request data from
the CPU module cannot be normally input.
A timeout error occurred in the dedicated
instruction response data, and the data was
discarded.
IP address change fails.
A communication error occurred in
MELSOFT connection.
Overlapping IP addresses were detected.
A parameter error was detected in the
external device configuration.
Action
• Check that there is no error in the set connection number.
(The connection number specified in the e-mail server connection
device with the external device configuration is specified by
another function.)
• Execute the write to program again.
If the error occurs again even after the above action is taken, the
possible cause is a hardware failure of the module on which the
error occurred. Please consult your local Mitsubishi
representative.
Recheck the values in 'MQTT connection setting' (Un\G108808 to
Un\G108823).
Check if 'Tool setting storage area write request' (Un\G108872)
and 'Tool setting storage area clear request' (Un\G108874) turned
from off to on simultaneously.
Recheck the values in 'Tool setting' (Un\G108879 to Un\G108895).
Check if 'Tool setting storage area write request' (Un\G108872)
and 'Tool setting storage area clear request' (Un\G108874) turned
from off to on simultaneously.
Check that the dedicated instruction is executable. If it is not
executable, correct it.
• Execute the write to program again.
• If the error occurs again even after the above action is taken, the
possible cause is a hardware failure of the module on which the
error occurred. Please consult your local Mitsubishi
representative.
• Execute the write to program again.
• If the error occurs again even after the above action is taken, the
possible cause is a hardware failure of the module on which the
error occurred. Please consult your local Mitsubishi
representative.
• Reset the CPU module, and execute it again.
• If the error occurs again even after the above action is taken, the
possible cause is a hardware failure of the module on which the
error occurred. Please consult your local Mitsubishi
representative.
• Execute the IP address change function again.
• If the error occurs again even after the above action is taken, the
possible cause is a hardware failure of the module on which the
error occurred. Please consult your local Mitsubishi
representative.
• Check the number of connected connections in the whole
MELSOFT connection.
• Check the number of UDP connections in the MELSOFT
connection.
Correct the IP address.
• Check the external device configuration settings in the FX5-
ENET module parameters.
• If the same error is displayed again, the abnormal module may
have a hardware problem. Please consult your local Mitsubishi
representative.
