A threshold for the sampled statistic. When the current sampled value is less than or equal to this threshold, and the value at the last sampling interval was greater than this threshold, a single event will be generated. A single event will also be generated if the first sample after this entry becomes valid is less than or equal to this threshold and the associated cFcAlarmStartupAlarm is equal to fallingcFcAlarm(2) or risingOrFallingAlarm(3). After a falling event is generated, another such event will not be generated until the sampled value rises above this threshold and reaches the cFcAlarmRisingThreshold. This object can only be used to set the lower word value of the threshold. If the threshold to be set is greater than 4,294,967,295, then cFcAlarmFallingThresholdHigh should be used to set the upper word value of the threshold.
