Action
• Take measures to reduce noise.
• Reset the CPU module, and run it again. If the same error occurs again
even after taking the above, the possible cause is a hardware failure of the
module, base unit, or extension cable. Please consult your local Mitsubishi
representative.
Reset the CPU module, and run it again. If the same error occurs again even
after taking the above, the possible cause is a hardware failure of the error
module or CPU module. Please consult your local Mitsubishi representative.
Reset the CPU module, and run it again. If the same error occurs again even
after taking the above, the possible cause is a hardware failure of the error
module. Please consult your local Mitsubishi representative.
Rewrite the module parameter using the engineering tool. If the same error
occurs again even after taking the above, the possible cause is a hardware
failure of the error module. Please consult your local Mitsubishi
representative.
Reset the CPU module, and run it again. If the same error occurs again even
after taking the above, the possible cause is a hardware failure of the error
module or CPU module. Please consult your local Mitsubishi representative.
Reset the CPU module, and run it again. If the same error occurs again even

module or CPU module. Please consult your local Mitsubishi representative.
Correct the port No. of the external device.
Correct the port Nos. of the Ethernet-equipped module and the external
device.
Correct the port Nos. of the Ethernet-equipped module and the external
device.
• Correct the IP address of the connected device in the network
configuration setting.
• Check that the IP address class of the connected device is set to A, B, or C
in the network configuration setting.
• Check the operation of the external device.
• Check if the open processing has been performed in the external device.
• When a firewall is set in the external device, check if access is permitted.
• Check if the Ethernet cable is disconnected.
Correct the specified IP address of the external device.
• Since there may be congestion of packets on the line, send data after a
certain period of time.
• 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 or switching hub.
• When the value of the 'Receive Buffer Status Storage Area'
(Un\G6291486) is 0001H, reduce the frequency of data received from the
external device.
• Check the settings for connection with the external device.
• Check the operation of the external device or switching hub.
• Since there may be congestion of packets on the line, send data after a
certain period of time.
• Check if the connection cable is disconnected.
• Check that there is no connection failure with the switching hub.
• Execute the PING test and communication status test, and if the test was
completed with an error, take the corrective action.
• Check the settings for connection with the external device.
• Check the operation of the external device or switching hub.
• Since there may be congestion of packets on the line, send data after a
certain period of time.
