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.
