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.
• 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)
When an error is detected, the error codes and time stamp are recorded in the
error log in RAM inside the FL-net Unit. Serious errors are also recorded in
EEPROM. The maximum number of errors that can be saved to EEPROM is
32. The errors recorded in EEPROM will be saved even if the Unit is restarted
or power is turned OFF. When the FL-net Unit is started, the contents of the
error log in EEPROM are copied to RAM.
When a FINS command is used to read the error log, the log held in RAM is
read. The error log cannot be cleared.
The FL-net Unit's error log can be read using the CX-FLnet or FL-net Unit
Support Software. The following FINS commands can also be used to read or
clear the error log. For details on each command, refer to 7-5 Command/
Response Reference.
