output is set or reset when a configured threshold is reached. The direction of count can be changed with
a signal at input Dir
You reset the output and the internal

R (Reset).
This function counts the 0 to 1 transitions

transitions.
Input Dir (Direction) determines the
direction of count:
Dir = 0: Up
Dir = 1: Down
On: On threshold
Value range: 0...99999999
Off: Off threshold
Value range: 0...99999999
StartVal: Initial value from which to begin
counting either down or up.
Retentivity set (on) = the status is
retentive in memory.
Q is set and reset according to the actual
value at Cnt and the set thresholds.
