3.4.25 Analog differential trigger
Short description
The output is set and reset depending on a configurable threshold and a differential value.
Connection Description
Input
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).
Parameter
Gain
Range of values: ± 10.00
B: Zero offset
Range of values: ± 10,000
On: On threshold
Range of values: ±20,000
Delta: Differential value for calculating the off parameter
Range of values: ± 20,000
p: Number of decimals
Range of values: 0, 1, 2, 3
Output
Q is set or reset, depending on the threshold and difference
values.
Parameter p (number of decimals)
Applies only to the display of On, Off and Ax values in a message text.
Does not apply to the comparison of On and Off values! (The compare function ignores
the decimal point.)
