This object specifies the boolean relation between
sensor value (entPhySensorValue) and threshold value
(ceSensorExtThresholdValue), required to
trigger the alarm.
in pseudo-code, the evaluation-alarm mechanism is:
...
if (evaluate(entPhySensorValue,
ceSensorExtThresholdRelation,
ceSensorExtThresholdValue))
then
if (((ceSensorExtThresholdNotifEnable
== enabled) ||
(ceSensorExtThresholdNotifEnable
== transparent)) &&
(ceSensorExtThresholdNotifGlobalEnable
== enabled))
then
raise_alarm(sensor's entPhysicalIndex);
endif
endif
