Parameter
The on-delay time T
H
and the off-delay time T
L
can be
provided by the actual 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)
Stopwatch (Ta)
The value of “T
H
” and “T
L
” can be set/modified in
parameter mode. For information about how to modify,
refer to chapter 5.2.2, please.
Timing diagram
With the 0 to 1 transition at input En, a random time (on
delay time) between 0 s and T
H
is set and triggered. If the
status at input En is 1 at least for the duration of the On
delay, the output is set to 1 when this On delay time has
expired.
The time is reset if the status at input En is reset to 0
before the On-delay time has expired.
When input En is reset 0, a random time (off delay time)
between 0 s and T
L
is set and triggered.
If the status at input En is 0 at least for the duration of
the off-delay time, the output Q is reset to 0 when the
off-delay time has expired.
