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.
To clear the entire error log, turn ON SR 25214 from a peripheral device.
(After the error log has been cleared, SR 25214 will turn OFF again automati-
cally.)
In SRM1 PCs, the error log is stored in DM 2000 through DM 2021.
The location for storing the next error record is shown. (0 to 7)
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 7 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 0
Error log record 1
Error log record 5
Error log record 6
2. You can store only the first 7 error log records, and ignore any subsequent
errors beyond those 7.
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.
To clear the entire error log, turn ON SR 25214 from a peripheral device.
(After the error log has been cleared, SR 25214 will turn OFF again automati-
cally.)
These error codes are received as the response code (end code) when a
command received by the PC from a host computer cannot be processed.
