f. Alarm Log File Format
The log file contains data in a flat, AS-
CII, CSV file. The following are the
fields of the file, in order of occurrence.
The days or months maintained in the
Alarm Log depends on how often trou-
ble conditions are recorded. If there
are rarely alarm conditions recorded,
there is enough space for many years
of alarm logs to be recorded.
