Timing diagram
Functional description
The function fetches the analog signal at input Ax.
Ax is multiplied by the value of the A (gain) parameter, and
the
value at para
meter B (offset) is added to product, i.e.
(Ax•gain) + offset = actual value of Ax.
Output Q is set or reset, depending on the set thresholds.
See the calculation ru
le below.
Calculation rule
If the On threshold Off th
reshold, then:
Q = 1, if the actual value Ax > On
Q = 0, if the actual value Ax Off.
If the On threshold < Off threshold, then Q = 1 if
On actual value Ax < Off.
