time has expired (the on-signal of the output follows the
on-signal of the input with delay).
The time is reset if the status at input Trg changes to 0
again before the time T has expired.
The output is reset to 0 when input Trg is 0.
Off-Delay
Description of function
The output with off delay is not reset until a defined time
has expired.
Connection
Description
Trg input ( )
Start the off-delay time with a
negative edge (1 to 0 transition) at
input Trg (Trigger)
Input R ( )
Reset the off-delay time and set the
output to 0 via the R (Reset) input.
Reset has priority over Trg
Parameter
T: The output is switched off on
the expiration of the delay time T
(output signal transition 1 to 0).
Retentivity on = the status is
retentive in memory.
Output Q
Q is switched on for the duration of
the time T after a trigger at input
Trg.
Parameter
The time set in parameter T can be supplied 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)
