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.
In CPM2C-S 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 indicates no records.
Each error log record is configured as follows:
Leading word
Leading word + 1
Leading word + 2
Note An error record with an error code of 00 will be stored in the error log for
power interruptions. Refer to 9-2 Self-diagnostic Functions for tables listing
the error codes.
Error Log Storage Methods
The error log storage method is set in the PC Setup (bits 00 to 03 of DM
6655). Set any of the following methods.
1. Set 0 in bits 00 to 03 of DM 6655. (This is the default setting.)
This method stores the most recent 7 error log records and discards 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.
2. Set 1 in bits 00 to 03 of DM 6655.
This method stores only the first 7 error log records, and ignores any sub-
sequent errors beyond those 7.
3. Set another value (other than 0 or 1) in bits 00 to 03 of DM 6655.
A setting other than 0 or 1 disables the log so that no records are stored.
Clearing the Error Log
To clear the entire error log, turn ON SR 25214 from a Programming Device.
(After the error log has been cleared, SR 25214 will turn OFF again automati-
cally.)
