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 registered
along with the error code. Refer to page 553 for error codes.
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
Error Log Storage Methods
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 re-
cords. 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.
3. You can disable the log so that no records are stored.
The default setting is the first method. Refer to Error Log Settings on page 21 for
details on the PC Setup for the error log.
Clearing the Error Log
To clear the entire error log, turn ON SR 25214 from a Programming Device. (Af-
ter the error log has been cleared, SR 25214 will turn OFF again automatically.)
In CPM2A/CPM2C PCs, the error log is stored in DM 2000 through DM 2021. Up
to 7 error records can be stored.
Indicates the number of records stored in the log (0 to 7). A 0 indi-
cates no records.
Each error log record is configured as follows:
