This timer function block realizes an on-delay timing.

If the input iN changes from FALSE to TRUE, switching on the output Q is delayed for the time interval at input PT. After the delay time PT has passed, the output Q is set to TRUE. The remaining time of the delay is provided at the output ET.



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


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