3) Pulse Timer Process Time Change and Contact On/Off
If input condition turns on, output contact (Q) turns on.
The process time is newly changed when the timer function block is executed. When the process time

The contact turns off after the setting time regardless of input condition off status.
The following diagram shows pulse timer timing.
