An input pulse increments or decrements an internal value,
depending on the parameter setting. The output is set or
reset when a configured threshold is reached. The
direction of count can be changed with a signal at input
Dir
Connection
Description
Input R ( )
You reset the output and the
internal counter value to zero with
a signal at input R (Reset).
Input Cnt ( )
This function counts the 0 to 1
transition at input Cnt. It does not
count 1 to 0 transitions.
Input Dir
Input Dir (Direction) determines the
direction of count:
Dir = 0: Up
Dir = 1: Down
Parameter
On: On threshold
Value range: 0...99999999
Off: Off threshold
Value range: 0...99999999
Start Val: Initial value from which to
begin counting either down or up.
Retentivity set (on) = the status is
retentive in memory.
Output Q
Q is set and reset according to the
actual value at Cnt and the set
thresholds.
Parameter
The on threshold On and the off threshold Off can be
provided by the value of another already-programmed
function:
Analog comparator (Ax – Ay) Analog threshold trigger
(Ax)
Analog amplifier (Ax) Analog multiplexer (AQ)
Analog ramp (AQ) Mathematic instruction
(AQ)
PI controller (AQ) Up/down counter (Cnt)
Analog filter (AQ) Average value (AQ)
Max/Min (AQ) On-delay (Ta)
Off-delay (Ta) On-/off-delay (Ta)
Retentive on-delay (Ta) Wiping relay(pulse output)
(Ta)
Edge triggered wiping relay (Ta)
Asynchronous pulse generator (Ta)
Stairway light switch (Ta) Multiple function switch (Ta)
