List of Error Codes

This section lists the error codes, error details and causes, and actions for the errors that occur in the processing for data
communications between the FX5-ENET/IP and external devices or that are caused by processing requests from the CPU
module on the own station.
The FX5-ENET/IP has the following error codes.
Type

EtherNet/IP communication error

Module error
Ethernet communication error
EtherNet/IP communication error
The EtherNet/IP communication error codes are stored in 'Class1 connection 1 to 32 error code' (Un\G6262 to Un\G6293).
The Class1 communication status 'Error status' (Un\G6034 to Un\6035) bit corresponding to the connection where the error
has occurred is turned on.

Action
• Take measures to reduce noise.
• Reset the CPU module, and then switch it to RUN mode. If the error
occurs again even after the above action is taken, the possible
cause is a hardware failure of the module. Please consult your local
Mitsubishi representative.
• Use EtherNet/IP Configuration Tool for FX5-ENET/IP to write the
parameters to the module again.
• When performing UCMM communications, check whether the
setting details of the UCMM request area are correct.
• Check whether the operating status of the external device is normal.
• Check for errors in the line status.
• The line may be busy, so retry at a later time.
• The external device may not be able to send data at the specified
RPI due to a high communication load, so specify a larger RPI and
connect again.
• Use EtherNet/IP Configuration Tool for FX5-ENET/IP to write the
parameters to the module 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.
• Take measures to reduce noise.
• Reset the CPU module, and then switch it to RUN mode. 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.
