Δ1: difference value above Aen:
on/off threshold
Range of values: 0 to 20,000
Δ2: difference value below Aen:
on/off threshold
Range of values: 0 to 20,000
p: Number of decimals
Range of values: 0, 1, 2, 3
Output Q
Q is set/reset, depending on the
stored analogue value and the
offset.
Parameter p (number of decimals)
The two threshold parameters Threshold 1 and Threshold
2 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 the display of Aen, Ax and Delta values in
a message text.
