List of Error Codes

This section lists the error codes, error details and causes, and actions for the errors that occur in the processing for data
communications between the RJ71EIP91 and EtherNet/IP devices or that are caused by processing requests from the CPU
module on the own station.
The RJ71EIP91 has the following error codes.
Type

Error codes when a module error occurs

Error codes when a communication error
occurs
Error codes when a module error occurs
Error codes when a module error occurs are classified into major error, moderate error, and minor error, and can be checked
in the [Error Information] tab of the "Module Diagnostics" window of the RJ71EIP91. ( Page 112 Error Information)
Error Error details and causes
code
1801H The number of writes to ROM exceeded 100000.
(Number of writes > 100000)
1807H A parameter error was detected.
1E00H An error was detected in the execution condition
during EtherNet/IP communications.
1E01H An error was detected in the execution condition
during execution of PING test.
1E03H An error was detected in the execution condition
during execution of connection information reading.
1E10H to An error was detected in the parameters set with
1E12H EtherNet/IP Configuration Tool.
1E13H to It was not possible to stop EtherNet/IP
1E14H communications.
2120H to A hardware failure has been detected.
2121H
2440H An error was detected in the I/O module or RJ71EIP91
during the initial processing.
Error code
1801H to 3FA0H
102H to 2FFH
Action
Replace the module.
Use the engineering tool to write the parameters to the
CPU module again.
Turn off the following signal, and then turn 'EtherNet/IP
communication start request' (Y10) on.
• 'PING test execution request' (Y12)
Turn off the following signals, and then turn 'PING test
execution request' (Y12) on.
• 'EtherNet/IP communication start request' (Y10)
• 'Connection information read request' (Y14)
• Turn off 'PING test execution request' (Y12), and
then turn on 'Connection information read request'
(Y14).
• Start EtherNet/IP communications, and then turn on
'Connection information read request' (Y14).
• Use EtherNet/IP Configuration Tool to write the
parameters to the module again.
• If the error occurs again even after the above action
is taken, the possible cause is a hardware failure of
the module on which the error occurred. Please
consult your local Mitsubishi representative.
• Check the settings of the connection with the
external device.
• If the error occurs again even after the above action
is taken, the possible cause is a hardware failure of
the module on which the error occurred. Please
consult your local Mitsubishi representative.
• If an SD memory card is loaded in the CPU module,
remove the SD memory card, reset the CPU
module, and then switch it to RUN mode.
• Take measures to reduce noise.
• Reset the CPU module, and then switch it to RUN
mode. If the error occurs again even after the above
action is taken, the possible cause is a hardware
failure of the module on which the error occurred.
Please consult your local Mitsubishi representative.
• Take measures to reduce noise.
• Reset the CPU module, and then switch it to RUN
mode. If the error occurs again even after the above
action is taken, the possible cause is a hardware
failure of the module on which the error occurred.
Please consult your local Mitsubishi representative.
