Description
A signal at input R resets the internal
count value to zero.
The function counts the 0 to 1
transitions at input Cnt. 1 to 0
transitions are not counted.
Use
• inputs I3, I4, I5, and I6 for fast
counting (only FL1E-H12RCE/
FL1E-B12RCE and FL1E-
H12SND): max. 5 kHz.
• any other input or circuit
component for counting low
frequency signals (typ. 4 Hz).
You set the direction of count at input
Dir:
Dir = 0: Up count
Dir = 1: Down count
On: On threshold
Range of values:
0...999999
Off: Off threshold
Range of values:
0...999999
StartVal: Initial value from which to
begin counting either down or up.
Retentivity for internal counter value
Cnt: 
/ = No retentivity
R = The status is retentive.
Q is set or reset, depending on the
current value at Cnt and the set
thresholds.
