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
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.
(Ay * gain) + offset = Actual value Ay.
Output Q is set or reset depending on the difference of the actual values Ax – Ay and the set
(Ax * gain) + offset = Actual value Ax.
(Ay * gain) + offset = Actual value Ay.
Output Q is set or reset depending on the difference of the actual values Ax – Ay and the set
thresholds. See the following calculation rule.
Calculation rule
● If threshold On ≥ threshold Off, then:
Q = 1, if (actual value Ax - actual value Ay) > On
Q = 0, if (actual value Ax - actual value Ay) ≤ Off.
● If threshold On < threshold Off, then Q = 1, then:
On ≤ (actual value Ax - actual value Ay) < Off.
0BA2, 0BA3:
The following functions/calculation rules apply:
The function adds the relevant specified offset to the analog values Ax and Ay.
The following functions/calculation rules apply:
The function adds the relevant specified offset to the analog values Ax and Ay.
The sum is multiplied with the value of the gain parameter. The difference is
formed from both calculated values.
Output Q is set if this difference between these values exceeds the threshold
Output Q is set if this difference between these values exceeds the threshold
you have configured under delta.
Calculation rule:
Calculation rule:
Q = 1, if:
((Ax + offset) * gain) - ((Ay + offset)*gain) > threshold delta
Q is reset to 0 when the threshold reaches or drops below delta.
