Error Log Storage Methods
1,2,3...
The error log function registers the error code of any fatal or non-fatal error
that occurs in the PC. The date and time at which the error occurred are regis-
tered along with the error code. Refer to page 437 for error codes.
In CQM1 PCs, the error log is stored in DM 6569 through DM 6599.
If a Memory Cassette without a clock is mounted, the date and time will be all
zeros.
Shows the number of error information items (0 to 7) stored in the
error log. "0" means that there are no items stored.
Each error log record is configured as follows:
15
Leading word
Leading word + 1
Leading word + 2
Error records will be stored even if pin 1 on the CQM1 DIP switch is turned
ON to protect DM 6144 to DM 6655.
In CPM1/CPM1A PCs, the error log is stored in DM 1000 through DM 1021.
The location for storing the next error record is shown. (0 to 6)
Each error log record is configured as follows:
Leading word
Leading word + 1
Leading word + 2
The error log storage method is set in the PC Setup (DM 6655). Set any of the
following methods.
1. You can store the most recent 10 error log records and discard older
records. This is achieved by shifting the records as shown below so that
the oldest record (record 0) is lost whenever a new record is generated.
Error log record 1
Error log record 2
Error log record 6
Error log record 7
2. You can store only the first 10 error log records, and ignore any subsequent
errors beyond those 10.
