Hysteresis
The function of the hysteresis is depending on the selected operator. No hysteresis func-
tion is possible for the operations AND or OR.
The hysteresis is defined as follows for the operators >=, <=, = and !=:
> =
Function:
Result:
A >= B
TRUE
A < (B – H)
FALSE
(B – H) < A < B
unchanged
< =
Function:
Result:
A <= B
TRUE
A > (B + H)
FALSE
(B + H) > A > B
unchanged
=
Function:
Result:
inside ± H/2
(B - H/2) < A < (B + H/2)
TRUE
outside ± H
A > (B + H) or A < (B - H)
FALSE
between H and H/2
unchanged
!=
Function:
Result:
inside ± H/2
(B - H/2) < A < (B + H/2)
FALSE
outside ± H
A > (B + H) or A < (B - H)
TRUE
between H and H/2
unchanged
