Shift down: S8 accepts the value of input In; the previous value of S8 is shifted
to S7, S7 is shifted to S6, etc.
Q outputs the value of the configured shift register bits.
If retentivity is not enabled, the shift function restarts at S1 or S8 after a power failure.
Note
The special function shift register can be used only once in the circuit program.
5.5.21 Analog comparator
Fashion: Classic:
Short description
The output is set and reset depending on the difference Ax - Ay and on two configurable thresholds.
Input the analog signals of which you want to
determine the delta at the inputs Ax and Ay.
Use the analog inputs AI1...AI8, the analog outputs
AQ1 and AQ2.
AI1..AI8: 0 - 10 V corresponds with 0 - 1000 (internal
value).
A: Gain
Range of values: ± 10.00
B: Zero offset
Range of values: ± 10,000
On: On threshold
Range of values: ± 20,000
Off: Off threshold
Range of values: ± 20,000
p: Number of decimals
Range of values: 0, 1, 2, 3
Q is set or reset depending on the set thresholds.
