IDEC SmartRelay Manual 161
4.4.13 Up/down counter
Short description
An input pulse increments or decrements an internal value,
dependin
g 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.

Wiring Description
Input R A signal at input R resets the internal
count value to zero.
Input Cnt 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).
Input Dir You set the direction of count at input
Dir:
Dir = 0: Up count
Dir = 1: Down count
Parameter 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.
Output Q Q is set or reset, depending on the
current value at Cnt and the set
thresholds.
