18.5.2 Configuring a digital output as an output with switching
thresholds
An output with switching thresholds switches depending on two threshold process values.
The output can switch either according to an hysteresis model or according to a window model.
Hysteresis switching
The output status changes when a threshold is reached:
•
by increasing values, the output state changes when the high threshold X+ is reached.
• by decreasing values, the output state changes when the low threshold X- is reached.

Window switching: the output state changes as soon as any threshold (X- or X+) is reached.
