4.4.17 Freuency trigger
Short description
The output is set and reset with two configurable freuency trigger.
Parameter GT
The gate time GT can be provided by the actual value of another already-programmed
function. ou can use the actual values of the following functions:
Analog comparator (Page 183)(actual value Ax Ay)
Analog trigger (Page 178) (actual value Ax)
Analog amplifier (Page 191) (actual value Ax)
Analog multiplexer (Page 209) (actual value A)
Analog ramp control (Page 212) (actual value A)
Analog Math (Page 224) (actual value A)
PI controller (Page 216) (actual value A)
Up/down counter (Page 168) (actual value Cnt)
Analog filter (Page 229) (actual value A)
Average value (Page 235) (actual value A)
Max/Min (Page 231) (actual value A)
On-delay (Page 132) (current time Ta)
Off-delay (Page 136) (current time Ta)
On-/off-delay (Page 138) (current time Ta)

iring Description
Input Fre The function counts the 0 to 1 transitions at input Fre.
1 to 0 transitions are not counted.
Use the following as the input:
inputs I3, I4, I5, I6 for fast counting (only FL1F-
H12RCE/B12RCE and FL1F-H12SCD): max.
5kHz, if the fast input is directly connected to the
freuency trigger function block
any other input or circuit component for counting
low freuency signals (typically 4Hz)
Parameter On: on threshold
Range of values:
0000...9999
Off: off threshold
Range of values:
0000...9999
GT: time interval or gate time during which the input
pulses are measured
Range of values:
00:00 s...99:99 s
Output is set and reset at the thresholds.
