9-11 Trouble Shooting
9-11-1 Error Log
The Ethernet Option Board provides an error log that records errors occurred
during Ethernet Option Board operation. The contents of the error log can be
read or cleared from the Web Brower.
Logged Errors
The following errors are recorded in the error log.
• Errors in network operation
• Errors in data transfers
• Error in the CPU unit
Error Log Table
Each error is recorded as one record in an error log table. Up to 64 records
can be saved. If more than 20 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.
• Main error code (see table later in this section)
• Detailed error code (see table later in this section)
• Time stamp (from the clock in the CPU unit)
Note
During the initialization of the Ethernet Option Board, if an error occurs, the
error log time stamp will record as 2000-00-00 00:00:00.
Error Log Location
When an error is detected, the error codes and time stamp are recorded in the
error log in RAM inside the Ethernet Option Board. Serious errors are also
recorded in EEPROM. The maximum number of errors that can be saved to
EEPROM is 20 for the CP1L and CP1H. The errors recorded in EEPROM will
be saved even if the unit is restarted or power is turned OFF.
