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), and
parameter B (offset) is then added to the product, i.e.
(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
± Delta.
Output Q is reset, when the actual value at input Ax lies within the range of Aen +- Delta, or when the
signal at input En changes to lo.

Short description
The output is set and reset depending on a configurable threshold and a differential value.
You apply the analog signal
to be analyzed at input Ax.
Use the analog inputs
AI1...AI8, the analog outputs
AQ1 and AQ2.
0 - 10 V is proportional to 0 -
1000 (internal value).
