Overview
Input Signal is Equal to X
Compare X To:
Limit A or
Limit B
Window*
(non-Hysterisis
Mode)
Window*
(Hysterisis Mode)
*
Value A defines the upper limit of the Window and Value B defines the low limit.

Criteria
Setpoint Definition:
• Equal to A
X = A
• Below A
X < A
• Above B
X > B
(Choose 1)
• Inside
B < X < A
• Outside
B > X; or X > A
(Choose 1)
• Above A
X > A
• Below B
X < B
(Both conditions
are checked when
in Hysterisis Mode)

Action
Driven by Condition
Update Conditions:
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
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
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.
