TP
This function block TP, a pulse generator, can be used to generate pulses with a defined pulse duration.
Inputs
VAR_INPUT
IN : BOOL; (* Trigger for Start of the Signal *)
PT : TIME; (* The length of the High-Signal in ms *)
END_VARName | Type | Description |
|---|---|---|
IN | BOOL | Trigger for the start of the signal |
PT | TIME | The length of the High signal in ms |
Outputs
VAR_OUTPUT
Q : BOOL; (* The pulse *)
ET : TIME; (* The current phase of the High-Signal *)
END_VARName | Type | Description |
|---|---|---|
Q | BOOL | Q supplies a signal over the interval specified in PT. |
ET | TIME | If IN = FALSE, the outputs are FALSE or 0. As soon as IN = TRUE, Q = TRUE and remains TRUE for the pulse duration PT. As long as Q = TRUE, the time in ET is incremented in milliseconds until the value reaches PT, then it remains constant. The output Q remains TRUE until the pulse duration has elapsed, irrespective of the state of the input IN. |
