System Log (AV35)
The Description field in this object provides a log of the ten most recent events from the least to the
most recent. If the time and date were previously set then the event time can also be determined. Each
log entry has the format [dd/mm/yy hh:mm:ss ***] where *** is the event code. Each event type is
specified by a letter, (H- Hardware, C- Communication, S-Service or O-Other) which is followed by a
two-digit code. For example, 02/05/06 10:12:47 S04. The PresentValue indicates how many items
are in the log.
