Hyst 1

Type Function module

Input IN	REAL (input value)
HIGH	REAL (upper threshold)
LOW	REAL (lower threshold)
Output Q	BOOL (output)
WIN	BOOL (shows that IN in between LOW and HIGH)
	HYST_1 is a hysteresis module that works with upper and lower limit. The output Q is only true if the input signal at IN has exceeded the value HIGH. It is then held true until the input signal falls below LOW and Q gets FALSE. A further output WIN indicates whether the input signal is between LOW and HIGH.
	The following example shows a triangular wave generator with downstream hysteresis hysteresis module HYST_1.
	The green line shows the input signal, red is the output hysteresis and blue the WIN.
