◆ Falling Threshold – If the current value is less than the falling
threshold, and the last sample value was greater than this threshold,
then an alarm will be generated. After a falling event has been
generated, another such event will not be generated until the sampled
value has risen above the falling threshold, reaches the rising
threshold, and again moves back down to the failing threshold.
(Range: -2147483647 to 2147483647)
◆ Falling Index – The index of the event to use if an alarm is triggered
by monitored variables crossing below the falling threshold. If there is
no corresponding entry in the event control table, then no event will be
generated. (Range: 1-65535)
