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.
