Timing diagram B: Function with positive difference Delta
Description of the function
The function fetches the analog signal at input Ax.
Ax is multiplied by the value of the A (gain) parameter, and the value at parameter 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 (On) threshold and difference value (Delta).
The function automatically calculates the Off parameter: Off = On + Delta, whereby Delta
may be positive or negative. See the calculation rule below.
Calculation rule
When you set a negative differential value Delta, the On threshold >= Off
threshold, and:
Q = 1, if the actual value Ax > On
Q = 0, if the actual value Ax
≤ Off.
