TP

IEC / CEI 1131-3 Compliant

This kind of timer has the same behavior of a single-shot timer or a monostable timer.

When a rising-edge ( OFF to ON or FALSE to TRUE ) transition is detected on the IN input, the Q output become immediately TRUE .

This condition continue until the programmed time PT, applied to the relative pin, is elapsed.

After that the programmed time is elapsed, the Q output keeps the ON state if the input IN is still asserted else the Q output returns to the OFF state.

This timer is not re-triggerable. This means that after the timer started it can't be stopped until the complete session ends.

The ET output pin reports the current elapsed time.

Plug	Description

IN	A rising-edge on this pin will trigger the pulse timer

PT	To this input user must apply the programmed time. User should use an IDENT object to enter a time constant

Q	When the pulse timer starts, and before that the programmed time is elapsed, this output become TRUE

ET	This output reports the current elapsed time
