A one-shot at the input triggers a configurable time. The output is set upon expiration of this time.
Trigger the on delay time via the Trg (Trigger) input.
Reset the time on delay time and reset the output to 0 via
input R (Reset).
Reset takes priority over Trg.
T is the on delay time for the output (output signal transition
0 to 1).
Retentivity on = the status is retentive in memory.
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 trigger: Ax
Analog amplifier: Ax
Analog multiplexer: AQ
Analog ramp: AQ
Analog math: AQ
PI controller: AQ
Data latching relay: AQ
Up/Down counter: Cnt
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
Description of the function
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 a1 signal at input R.
If retentivity is not set, output Q and the expired time are reset after a power failure.
