Parameter p (number of decimals)
Parameter p applies only to the display of Aen, Ax, Threshold 1 and Threshold 2 values in a
message text.

Description of the function
A 0 to 1 transition at input En saves the value of the signal at the analog input Ax. This saved
process variable is referred to as "Aen".
Both the analog actual values Ax and Aen are multiplied by the value at parameter A (gain),
Both the analog actual values Ax and Aen are multiplied by the value at parameter A (gain),
and parameter B (offset) is then added to the product, as follows:
(Ax * gain) + offset = Actual value Aen, when input En changes from 0 to 1, or
(Ax * gain) + offset = Actual value Ax.
Output Q is set when the signal at input En = 1 and if the actual value at input Ax is out of
(Ax * gain) + offset = Actual value Aen, when input En changes from 0 to 1, or
(Ax * gain) + offset = Actual value Ax.
Output Q is set when the signal at input En = 1 and if the actual value at input Ax is out of
range of Aen + Threshold 1 / Aen - Threshold 2.
Output Q is reset, when the actual value at input Ax lies within the range of Aen + Threshold
Output Q is reset, when the actual value at input Ax lies within the range of Aen + Threshold
1 / Aen - Threshold 2, or when the signal at input En changes to lo.
