Parameter p (number of decimals)
The on threshold On and the off threshold Off can be provided by the actual value of another
already-programmed function:
Analog comparator: Ax – Ay
Analog trigger: Ax
Analog amplifier: Ax
Analog multiplexer: AQ
Analog ramp: AQ
Analog math: AQ
PI controller: AQ
Data latching relay: AQ
Up/Down counter: Cnt
Applies only to Ax, Ay, Delta, On and Off values displayed in a message text.
Does not apply to the comparison of on and off values! (The compare function ignores the decimal point.)
The value of ＂On＂,＂Off＂and ＂Dec＂ can be set/modified in parameter mode. For information about
how to set/modify, refer to chapter 5.2.2 please.(Dec means decimal point.)

Q for Ax - Ay > 200, On = Off = 200
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.
(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.
