CJ-series EtherNet/IP Units Operation Manual for NJ-series CPU Unit (W495)
13-4 Error Log
Errors detected by the EtherNet/IP Unit are stored in the error log along with the date and time of their
occurrence. The error log can be read from the Network Configurator and cleared from the Sysmac
Studio.
Error Descriptions
A short description of the error is given.
Detailed Error Code
The detailed error code provides further troubleshooting information on the error.
Refer to 13-4-2 Error Log Error Codes for the error descriptions and detailed error codes.
Clock Information
The year, month, day, hour, minutes, and sections that the error occurred are recorded.
Additional Information
The EtherNet/IP Unit reads and uses the clock information from the CPU Unit.
If the EtherNet/IP Unit cannot read the clock information from the CPU Unit, the clock time in the
error log will be all zeros.
The correct time is not recorded if the internal clock is not set correctly. If such an error record is
read, the clock information will be invalid.
Error Log Data in RAM
When an error occurs, one record is stored in the error log table in RAM inside the EtherNet/IP Unit.
Up to 64 records are recorded.
Error Log Data in Non-volatile Memory
When a high-priority error occurs, a record is stored both in the error log table in RAM and in the
error log table in non-volatile memory in the EtherNet/IP Unit. The contents of the error log table in
non-volatile memory is retained even if the power supply to the Controller is turned OFF or the Con-
troller is reset. (When the Controller is reset, the error log table in the non-volatile memory is auto-
matically loaded to the error log table in RAM.) One record is stored in the non-volatile memory for
each error. Up to 32 records are stored. When the maximum number of records is exceeded, the
oldest records are deleted and only the newest records are retained. (The maximum number of
records is 64 for RAM and 32 for the non-volatile memory.)
Clearing Error Log Data
You can use the Controller event log functions of the Sysmac Studio to clear the error log data from
the RAM or non-volatile memory in the EtherNet/IP Unit.
