4.5 List of Error Codes
Action
• Set the own station send range so that the common parameter  unique
parameter of each station.
• If there is no parameter unique to the station, the error is the hardware
failure of the CPU module or network module. Please consult your local
Mitsubishi representative.
Please consult your local Mitsubishi representative.
• Change the module parameter setting to the one set for the sub-control
station. Or, activate the own station as a control station.
• If the error occurs again, the error is the hardware failure of the CPU
module or network module. Please consult your local Mitsubishi
representative.
Set "Control Station Shift Setting" under "Supplementary Cyclic Settings"
in "Application Settings" to "Set".
For the station equipped with a redundant system, set "Network Range
Assignment" of "Required Settings" to "Enable".
Change the network type of the normal station to the one set for the
control station.
Please consult your local Mitsubishi representative.
• If the data link stop is performed for the station by all stations
specification, activate the data link by setting all stations specification.
• If the data link stop is performed for the station by station specification,
activate the data link by setting station specification from the data link
stop station or forcibly activate the station.
Activate the data link from the station that stopped the data link. Or,
forcibly start the data link.
• If a communication error occurs, correct the communication cable.
• If no communication error has occurred, the error is caused by hardware
failure. Please consult your local Mitsubishi representative.
• If a communication error occurs, correct the communication cable.
• If no communication error has occurred, the error is caused by hardware
failure. Please consult your local Mitsubishi representative.
Check the control station status to see if reset or error has occurred during
transmission.
Check if the control station exists. If the control station exists, correct the
network parameter setting and write data to the programmable controller.
If the control station does not exist, add a control station.
Check the setting and stop or restart cyclic transmission.
Check if the following conditions are satisfied.
• The system is a multiplexed remote I/O network system.
• The parameter of the master station is set to "Returns as Control
Station".
• The own station is operating as the master station.
• The submaster operating station is performing data link.
Please consult your local Mitsubishi representative.
• Correct the network parameter setting and write data to the
programmable controller.
• If the error occurs again, the error is the hardware failure of the CPU
module or network module. Please consult your local Mitsubishi
representative.
