Input En
Input Ax
Parameter
Output Q
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 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 the display of Aen, Ax and Delta values in a message text.
Timing diagram
Description
A positive edge (0 to 1 transition) at input En saves
the analog value at input Ax ("Aen") to memory and
starts monitoring of the analog range Aen ± Delta.
You apply the analog signal to be monitored 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).
A: Gain
Range of values: ± 10.00
B: Zero offset
Range of values: ± 10,000
Delta: Difference value for the Aen on/off threshold
Range of values: ± 20,000
p: Number of decimals
Range of values: 0, 1, 2, 3
Q is set/reset, depending on the stored analog value
and the offset.
