3.5 List of Error Codes
Action
• Correct the IP address in "Network/Station No. <-> IP
information setting" under "Application Settings".
• Check if the network or station number of the external
device is correctly specified by using control data of the
dedicated instruction.
Check the error of the CPU module and take action using
the module diagnostics of the engineering tool.
Lower the transient transmission usage frequency, and
then perform again.
Correct the transient transmission execution count.
The hardware failure of the CPU module may have been
occurred. Please consult your local Mitsubishi
representative.
Check and correct the IP addresses.
Check the detailed information of the error by executing
module diagnostics using the engineering tool, and write
the displayed parameter. If the error occurs again even
after taking the above, the possible cause is a hardware
failure of the module. Please consult your local Mitsubishi
representative.
Check the detailed information (parameter information) of
the error by executing module diagnostics using the
engineering tool, and correct the parameter setting
corresponding to the displayed number (parameter
number). If the same error code is displayed again, the
possible cause is a hardware failure of the data memory
of the CPU module, a memory card, the I/O module, or
intelligent function module. Please consult your local
Mitsubishi representative.
Write the protocol setting data for the Ethernet-equipped
module to the CPU module.
• Take measures to reduce noise.
• Reset the CPU module, and run it again. If the 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.
• Take measures to reduce noise.
• Reset the CPU module, and run it again. If the 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.
• Check the each system port number registered in the
buffer memory.
• If the 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.
• Increase the request interval.
• Decrease the number of request nodes.
• Wait for a response to the previous request before
sending the next request.
• Correct the timeout value.
• Check and change the send data size of the Ethernet-
equipped module or the external device.
• If the same error code is displayed again, the possible
cause is a hardware failure of the error module or CPU
module. Please consult your local Mitsubishi
representative.
