Short description
An input signal generates an output signal of a configurable length.
Connection |
Description |
Input Trg |
You trigger the time for the wiping relay with a signal at input Trg (Trigger). |
Parameter |
T represents the time after which the output is reset (output signal transition 1 to 0). Retentivity set (on) = the status is retentive in memory. |
Output Q |
A pulse at Trg sets Q. The output stays set until the time T has expired and if Trg = 1 for the duration of this time. A 1 to 0 transition at Trg prior to the expiration of T also resets the output to 0. |
Parameter T
The off time T can be provided by the actual 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
Up/Down counter: Cnt
You select the required function by the block number.
Timing diagram
Description of the function
With the input signal Trg = 1, output Q is set to 1. The signal also triggers the time Ta, while the output remains set.
When Ta reaches the value defined at T (Ta=T), the output Q is reset to 0 state (pulse output).
If the signal at input Trg changes from 1 to 0 before this time has expired, the output is immediately reset from 1 to 0.
