Description
Input Ax
Input Ax is one of the following analog signals:
•
•
AI1 to AI8 (*)
•
AM1 to AM64
•
NAI1 to NAI32
•
AQ1 to AQ8
•
NAQ1 to NAQ16
•
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
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
Off: off threshold
Range of values: -20,000 to 20,000
p: number of decimals
p: number of decimals
Range of values: 0, 1, 2, 3
Output Q
Q is set or reset by the threshold triggers.
* AI1...AI8: 0...10 V corresponds with 0...1000 (internal value).
Gain and offset parameters
Please note the information on gain and offset parameters in topic "Calculating the gain and
offset of analog values (Page 130)".
Parameters On and Off
The actual value of another already-programmed function can provide the On and Off
parameters. You can use the actual values of the following functions:
● Analog comparator (Page 188) (actual value Ax – Ay)
● Analog amplifier (Page 195) (actual value Ax)
● Analog multiplexer (Page 213) (actual value AQ)
● Analog ramp (Page 216) (actual value AQ)
● Mathematic instruction (Page 227) (actual value AQ)
● PI controller (Page 220) (actual value AQ)
● Up/down counter (Page 173) (actual value Cnt)
● Analog comparator (Page 188) (actual value Ax – Ay)
● Analog amplifier (Page 195) (actual value Ax)
● Analog multiplexer (Page 213) (actual value AQ)
● Analog ramp (Page 216) (actual value AQ)
● Mathematic instruction (Page 227) (actual value AQ)
● PI controller (Page 220) (actual value AQ)
