| Description | This variable indicates the relation between sensor value
(entSensorValue) and threshold value (entSensorThresholdValue),
required to trigger the alarm. when evaluating the relation,
entSensorValue is on the left of entSensorThresholdRelation,
entSensorThresholdValue is on the right.
in pseudo-code, the evaluation-alarm mechanism is:
...
if (entSensorStatus == ok) then
if (evaluate(entSensorValue, entSensorThresholdRelation,
entSensorThresholdValue))
then
if (entSensorThresholdNotificationEnable == true))
then
raise_alarm(sensor's entPhysicalIndex);
endif
endif
