The Level Detector function has three analog inputs Signal, HiLimitSignal,
LoLimitSignal and one digital output Status. It holds two parameters, HiLimit and
LoLimit.
The incoming Signal is compared with two values, Hi and Lo. When the value of
the Signal input becomes greater than the value of Hi Status is set to True. Status
remains True until Signal becomes less than Lo and then it becomes False. Status
remains False until Signal becomes greater than Hi again and then it becomes
True.
If LoLimitSignal = Off, then LoLimitValue is used for Lo, otherwise
LoLimitSignal is used. If HiLimitSignal = Off, then HiLimitValue is used for Hi,
otherwise HiLimitSignal is used. In short, if the input is connected, the value of
the input is used, otherwise the value of the parameter is used. It is possible to
have one input connected and the other unconnected.
