Description :
The function block TP is used to generate some pulses for a specific period of time. When the activation input (IN) becomes true, the output bit (Q) is active. That bit remains true for the pulse specified in the preset time (PT). When the elapsed time (ET) becomes equal to the preset time (PT), the output bit (Q) becomes false. The elapsed time remains true until the activation input becomes false. When the output bit becomes true, it remains true until the time elapsed is the preset time (PT).
The timer TOF has the resolution of 1 ms.
