A one-shot at the input triggers a configurable time. The output is set upon expiration of this time.
Connection Description
Input Trg Trigger the on delay time via the Trg (Trigger) input.
Input R Reset the time on delay time and reset the output to 0 via
input
R (Reset).
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 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.
