- [Instructor] I'm going to go through an example that covers all the concepts we've learned so far. This example has two parts. For part one, we will develop a Ladder Logic program, to start and stop a conveyor belt. So for part one, the example is, a normally open push button, to start a conveyor and manufacturing setting. As soon as the operator pushes the Start pushbutton, and let go, the conveyor starts and stays on. There is a Stop pushbutton, so once the operator presses on it, the conveyor stops. The Stop pushbutton is a normally open relay as well. So Start and Stop pushbuttons are Inputs, and both are normally open contacts. The Conveyor is an Output. So let's start programming, by knowing How to Start the Conveyor. Since we're using a normally open for the Start pushbutton, to start the conveyor. So in the Ladder Logic, we are going to use an XIC instruction. And a regular output for the conveyor. And in order to keep the conveyor on, in order to keep the conveyor working…
