Description of the function
The function reads the value of the signal at the analog input Ax.
This value is multiplied by the value of parameter A (gain). Parameter B (offset) is added to the product,
hence
(Ax ∙Gain) + Offset = Actual value Ax.
Output Q is set or reset depending on the set threshold values. See the following calculation rule.
Calculation rule
If threshold (On) ≥ threshold (Off), then:
Q = 1, if the actual value Ax > On
Q = 0, if the actual value Ax ≤Off.
If threshold (On) < threshold (Off), then Q = 1, if
On ≤ the actual value Ax < Off.
Note
The decimal point setting must be identical in the min. and max. range.
Setting the Par parameter
The gain and offset parameters are used to adapt the sensors to the relevant application.
