Error Log
Section 9-3
9-3
Error Log
The error log records errors that occur in the Controller Link Support Board
and the time they occur. The error log can be read or cleared using the Con-
troller Link Support Software, a PC Programming Device, such as the SYS-
MAC Support Software, or the message service (FINS commands for the
Controller Link Support Board.)
9-3-1
Error Log Table
Errors are recorded in an error log table in the Board’s RAM, with one record
for each error and a maximum of 39 records.
Serious errors are also recorded in the Board’s EEPROM so that when the
power to the Board is turned OFF or reset, a record of the error will remain.
(The error log table in EEPROM automatically reads the Board’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.
Error Log Table Configuration
Time Information
The time is recorded in BCD with one byte each for the year (the rightmost
two digits), month, day, hour, seconds, and minutes of the time the error
occurred.
Note
The computer’s time information can be read and used in the Controller Link
Support Board. When the time cannot be read from the computer, all error log
times will be 0. When error logs are read from the Controller Link Support
Software, they will be dated 0 s, 0 min, 0 hr, 0 day, 0 month, 2000.
