Error details
System error (The processing order in OS is
abnormal.)
Connection to the module was unsuccessful or
interrupted.
System error (The I/O control processing is
abnormal.)
Data cannot be sent because the receive area of
the external device does not have enough free
space.
The port number setting for the CPU module is
incorrect.
The port number setting for the target device is
invalid.
• 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.
• For UDP/IP, the same Host station port No. is
specified as MC protocol.
• For UDP/IP, the specified host station No. is
duplicated.
The IP address setting of the target device for
OPEN processing is invalid.
Connection was not established in OPEN
processing for TCP connection.
Corrective action
• 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.
• 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.
• 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.
• 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.
Correct the port number.
Correct the port number.
• Specify a port number different from that used in
the MC protocol.
• Change the port number of the CPU module or
external device.
• Specify a port number that is not duplicated with
that of MC protocol.
• Correct the port number of the CPU module to
avoid duplication.
Correct the IP address. Specify A, B, or C for the
class.
• 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.
