o
Equal To: if the sensor value is equal to the threshold value.
o
Not Equal To: if the sensor value is not equal to the threshold value.
Indicates the relation between sensor value (SensorValue) and threshold value (SensorThresholdValue),
required to trigger the alarm.
When evaluating the relation, SensorValue is on the left of SensorThresholdRelation, and
SensorThresholdValue is on the right (e.g., SensorValue ≥ SensorThresholdValue).
Value
: defines the value of the threshold (e.g., for a Major threshold severity selection, set a relation of
Greater than or equal to 14000 as the requirement for notification). To correctly display or interpret this
variable's value, you must also know the SensorType, SensorScale, and SensorPrecision. However, you
can directly compare SensorValue with the threshold values given in the SensorThresholdTable without
any semantic knowledge.
Notification
: select Enabled to be informed of Temperature Sensor events, or select Disabled to not
receive notification of Temperature Sensor events. If this value is
Disabled
, then no
SensorThresholdNotification will be generated on this device. If this value is
Enabled
, then whether a
SensorThresholdNotification for a threshold will be generated or not depends on the instance value of
SensorThresholdNotificationEnable for that threshold.
Last Evaluation
: displays
True
if parameters were included in the most recent measurement, otherwise
displays
False
. This value indicates the result of the most recent evaluation of the threshold. If the
threshold condition is True, then SensorThresholdEvaluation is True. If the threshold condition is False,
then SensorThresholdEvaluation is False. Thresholds are evaluated at the rate indicated by the
SensorValueUpdateRate (e.g., 0=
on demand when polled), when the sensor value changes (event-
driven), or the agent does not know the update rate.
