Functional description
The internal counter increments (Dir = 0) or decrements (Dir
= 1) by one count with every positive edge at input Cnt.
You can use input R to reset the output and the internal
count value to ‘000000’. As long as R = 1, the output is also
lo and the pulses at input Cnt are not counted.
If retentivity is not set, output Q and the expired time are re-
set after a power failure.
Q is set or reset depending on the current value at Cnt and
the set thresholds. See the calculation rule below.
Parameter On: On threshold
Range of values:
0...999999
Off: Off threshold
Range of values:
0...999999
Retentivity for internal
counter value Cnt:
/ = No retentivity
R = The status is retentive.
Output Q Q is set or reset, depending
on the current value at Cnt
and the set thresholds.
