4.4.18 Analog trigger
Short description
The output is set and reset at two configurable thresholds.
Gain and offset parameters
Please note the information on gain and offset parameters in topic Calculating the gain and
offset of analog values (Page 126).
Parameters On and Off
The actual value of another already-programmed function can provide the On and Off
parameters. ou can use the actual values of the following functions:
Analog comparator (Page 183)(actual value Ax Ay)
Analog amplifier (Page 191) (actual value Ax)
Analog multiplexer (Page 209) (actual value A)
Analog ramp control (Page 212) (actual value A)
Analog Math (Page 224) (actual value A)
PI controller (Page 216) (actual value A)
Up/down counter (Page 168) (actual value Cnt)
Analog filter (Page 229) (actual value A)
Average value (Page 235) (actual value A)
Max/Min (Page 231) (actual value A)

NA1 to NA16
Block number of a function with analog output
Parameter A: gain
Range of values: -10.00 to 10.00
B: zero offset
Range of values: -10,000 to 10,000
On: on threshold
Range of values: -20,000 to 20,000
Off: off threshold
Range of values: -20,000 to 20,000
p: number of decimals
Range of values: 0, 1, 2, 3
Output is set or reset by the thresholds.
AI1...AI8: 0...10 V corresponds with 0...1000 (internal value).
