You can set a hysteresis range that applies to all configured thresholds on an analog input configuration.
Figure 1. Hysteresis
Refer to the following guidelines when setting a hysteresis value for your analog configurations:
The hysteresis range affects both the rising edge and the falling edge of the incoming signal. A hysteresis value of 0.100
mA filters the incoming signal between +0.100 mA and -0.100 mA of each configured threshold value.
Figure 2. Hysteresis Range for Input Signals
The User Program applies the hysteresis value to all four thresholds. The hysteresis range of one threshold can not overlap
the hysteresis range of another threshold.
In dual input and triple input configurations, the hysteresis and threshold values apply to every channel in that configuration.
