Error Log Section 9-3
9-3 Error Log
The error log records errors that occur in the Controller Link Unit and the time
they occur. The error log can be read or cleared by using Programming
Devices, such as the Controller Link Support Software, the CX-Net, or Sup-
port Software for the CPU Unit (SYSMAC Support Software), or by using the
message service (FINS commands for the Controller Link Unit.)
9-3-1 Error Log Table
Errors are recorded in an error log table in the Unit’s RAM, with one record for
each error and a maximum of 39 records.
Errors of significance are also recorded in the Unit’s EEPROM so that when
the power to the Unit is turned OFF or reset, a record of the error will remain.
(The error log table in EEPROM automatically reads the Unit’s RAM when the
power is turned ON again.)
If the number of records exceeds 39, the oldest record will be deleted and the
most recent error recorded.
