Following are descriptions for the categories shown in the Alarm Table:
♦ Owner
The entity that configured the entry and is therefore using the
resources assigned to it.
♦ Index
An index uniquely identifying an entry in the alarm table. Each
such entry defines a diagnostic sample at a particular interval.
♦ Interval
The interval in seconds over which the data is sampled and
compared with the rising and falling thresholds. When setting this vari-
able, care should be taken in the case of Delta sampling – the interval
should be set short enough that the sampled variable is very unlikely to
increase or decrease by more than 2^31
−
1 during a single sampling in-
terval.
♦ Variable
The object identifier of the particular variable to be sampled.
♦ Sample Type
The method of sampling the selected variable and cal-
culating the value to be compared against the thresholds. If the value of
this object is
Absolute
, the value of the selected variable will be com-
pared directly with the thresholds at the end of the sampling interval. If
the value of this object is
Delta
, the value of the selected variable at the
last sample will be subtracted from the current value, and the difference
compared with the thresholds.
