6.4.3 Text Format Log files
The Alarm Event and Totalizer Logs for each Process Group and the Audit Log are archived into individual
files. The filenames are formatted as shown in Table 6.4 with the date and the time indicating the first entry
in the file.
If one of the archive log files becomes full (>65000 entries) a new file is created with an extension
incremented by 1, e.g. a01, e01 etc.
New text format log data files are also created when the daylight saving period starts or ends.
Files containing log data generated during the daylight saving period (summertime) have '~DS' appended
to the filename.
Note.
Hourly files start exactly on the hour.
Daily files start at 00:00:00.
Monthly files start at 00:00:00 on the first of the month.
