The Retractive Switch function block can be used to generate pulses via the visualization (user interface) and via logic.
A pulse at the output (Q) can be generated via the button in the visualization or via a preceding logic. The duration of the pulse is determined by parameter T, pressing the button in the user interface or having another trigger input (Tr) will reset the timer.
When a reset signal (R input) is used, the output is switched off immediately. A continuous signal on R has priority over Tr.
If a signal input is in the input Dis, the other inputs Tr and R are ignored. However, the button in the visualization.
|Tr||Trigger||Button input Sets the output to ON and starts the timer|
|R||Reset||Resets the output (Q).|
|Dis||Disable||Locks all inputs. The module can still be operated via the visualization.|
|Q||Digital output||Digital output is activated when the button is pressed and deactivated when the time T has elapsed|
|T||Time||Duration of the output pulse|
