Error Log
Section 12-3
12-3 Error Log
Each time an error occurs, the CPU Unit stores error information in the Error
Log Area of the Auxiliary Area (A100 to A199). The error information includes
the error code (stored in A400), error contents, and time that the error
occurred. Up to 20 records can be stored in the Error Log.
In addition to system-generated errors, the CPU Unit records user-defined
errors, making it easier to track the operating status of the system.
When more than 20 errors occur, the oldest error data (stored in A100 to
A104) is deleted, the 19 errors stored in A105 to A199 shift one record, and
the newest record is stored in A195 to A199.
The number of records stored in the error log is stored in the Error Log Pointer
(A300). The Error Log Pointer is not incremented after 20 records have been
stored.
