This timer function block creates a pulse.

If the input iN changes from FALSE to TRUE, a pulse is created at output Q for the time interval provided at input PT. The remaining time of the pulse is provided at the output ET. If iN gets TRUE for another time and PT has not been elapsed, it has no impact on the duration of the pulse created at output Q.



Name I/O Type(s) Function
iN I BIT Input signal
PT I TIME Preset time interval for the pulse
Q O BIT Output signal
ET O TIME Remaining time of the pulse


If the output Q is set to TRUE, the function block will be highlighted.
