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 threshold trigger
(Ax)
Analog amplifier (Ax) Analog multiplexer (AQ)
Analog ramp (AQ) Mathematic instruction
(AQ)
PI controller (AQ) Up/down counter (Cnt)
Analog filter (AQ) Average value (AQ)
Max/Min (AQ) On-delay (Ta)
Off-delay (Ta) On-/off-delay (Ta)
Retentive on-delay (Ta) Wiping relay(pulse output)
(Ta)
Edge triggered wiping relay (Ta)
Asynchronous pulse generator (Ta)
Stairway light switch (Ta) Multiple function switch
(Ta)
Stopwatch (Ta)
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.

Q for Ax - Ay > 200, On = Off = 200
Description of function
The function reads the value of the signal at the analogue
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.
