Error
System error (The processing order in OS is
abnormal.)
• Check that the power supply module and the
CPU module are mounted/connected properly.
• Check that the system is operating within the
general specifications of the CPU module.
• Check whether the power capacity is sufficient.
• Reset the CPU module.
• Execute again. If the same error code is
displayed, the cause is a hardware failure of the
CPU module. Please consult your local
Mitsubishi representative.

Ethernet I/F
Error
Connection to the module was unsuccessful or
interrupted.
• Check the external device operation.
• Check the status of devices (such as cables,
hubs, and routers) on the line to the external
devices.
• Retry to connect a little while later, if the error
occurred in communication.

Error
System error (The I/O control processing is
abnormal.)
• Check that the power supply module and the
CPU module are mounted/connected properly.
• Check that the system is operating within the
general specifications of the CPU module.
• Check whether the power capacity is sufficient.
• Reset the CPU module.
• Execute again. If the same error code is

H
Ethernet I/F
Error
Data cannot be sent because the receive area of
the external device does not have enough free
space.
• Send the data again a little while later.
• Check the external device operation.
• Check whether the external device processes
receive data.
• Check whether the CPU module does not send
unnecessary data.
• Check the size and frequency of sent data and
reduce the amount of send data.
• To send data again, close the connection and
discard data. Then, re-open the connection and
send data.

Ethernet I/F
Error
• The own station port number same as that of
the MC protocol has been specified in TCP/IP.
• In TCP/IP, connection with the same own
station port number and same communication
destination port number has been used for the
same communication destination.
• Specify a port number different from that used in
the MC protocol.
• Change the port number of the CPU module or
external device.

Error
• For UDP/IP, the same Host station port No. is
specified as MC protocol.
• For UDP/IP, the specified host station No. is
duplicated.
• Specify a port number that is not duplicated with
that of MC protocol.
• Correct the port number of the CPU module to
avoid duplication.

Error
Connection was not established in OPEN
processing for TCP connection.
• Check the external device operation.
• Check OPEN processing of the target device.
• Correct the port number of the CPU module and
the IP address, port number, and open
processing method of the target device.
• Check whether the cables are securely
connected.
