Input R ( )
Reset the time on delay time and
reset the output to 0 via input R
(Reset).
The reset takes priority over Trg.
Parameter
T is the on-delay time for the
output (output signal transition 0 to
1).
Retentivity on = the status is
retentive in memory.
Output Q
Q is switched on upon expiration of
the time T.
Parameter
The time in parameter T can be provided 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)
Stopwatch (Ta)
The value of “T” can be set/modified in parameter mode.
For information about how to modify, refer to chapter
5.2.2, please.
Timing diagram
The current time Ta is triggered with a 0 to 1 signal
transition at input Trg. Output Q is set to 1 when Ta
reaches the time T. A further pulse at input Trg does not
affect Ta.
The output and the time Ta are only reset to 0 with a ‘1’
signal at input R.
If retentivity is not set, output Q and the expired time are
reset after a power failure.
