Error Log Error Codes
Meaning
Each error is recorded as one record in an error log table. Up to 64 records
can be saved. If more than 64 errors occur, the oldest errors will be deleted
from the error log and the most recent error will be recorded.
The following information is recorded in the error log table.
When an error is detected, the error codes and time stamp are recorded in the
error log in RAM inside the Ethernet Unit. Serious errors are also recorded in
EEPROM. The maximum number of errors that can be saved to EEPROM is
64 for the CS Series and 32 for the CJ Series. The errors recorded in
EEPROM will be saved even if the Unit is restarted or power is turned OFF.
When the Ethernet Unit is started, the contents of the error log in EEPROM is
copied to RAM.
When a FINS command is used to read the error log, the log held in RAM is
read. When a FINS command is used to clear the error log, the logs held in
both RAM and EEPROM are cleared.
The following FINS commands can be used to read or clear the error log.
Refer to SECTION 7 FINS Commands Addressed to Ethernet Units.
The error codes are described in the following table. The detailed error code
will provide detailed information on an error.
