Overview 
 
Criteria 
Input Signal is Equal to X 
Action 
Driven by Condition 
Compare X To: 
Setpoint Definition: 
Update Conditions: 
Limit A or 
Limit B 
 
•  Equal to A 
•  Below A  
•  Above B 
 
(Choose 1) 
X = A  
X < A 
X > B 
  
 
True Only
If True, then Output Value 1 
If False, then perform no action 
True and False
If True, then Output Value 1 
If False, then Output Value 2 
Window* 
(non-Hysterisis 
Mode) 
•  Inside 
•  Outside 
(Choose 1) 
B < X < A 
B > X; or X > A 
True Only
If True, then Output Value 1 
If False, then perform no action 
True and False
If True, then Output Value 1 
If False, then Output Value 2 
Window* 
(Hysterisis Mode) 
•  Above A 
•  Below B 
 
(Both conditions 
are checked when 
in Hysterisis Mode)
 
X > A 
X < B 
Hysterisis Mode (Forced Update)
If X > A is True, then Output Value 1 until 
X < B is True, then Output Value 2.   
If X < B is True, then Output Value 2 until X > A 
is True, then Output Value 1. 
This is saying: (1) If the input signal is outside 
the window “high”, then Output Value 1 until the 
signal goes outside the window “low” and (2) if 
the signal is outside the window low, then 
Output Value 2 until the signal goes outside the 
window “high.”  There is no change to the 
detect signal while within the window. 
Value A defines the upper limit of the Window and Value B defines the low limit.
