In this video, you will learn the PLC timer programming with generate off delay timer.
The generate off-delay timer is called as TOF instruction in Siemens Tia Portal.
You can use the "Generate off-delay" instruction to delay resetting of the Q output by the programmed time PT.
When the signal state at input IN changes back to "1", the programmed time PT starts.
Output Q remains set as long as the time duration PT is running. When the PT time duration expires, the Q output is reset.
