Ladder logic program simulation

Ladder logic program simulation

- [Instructor] So this is how the program looks like so far. Start push button that starts the process, when 12 sheets are stacked the conveyor moves to Position B. Sensor B is used to stop the conveyor and the paint is applied for 10 seconds. After painting is complete, the conveyor then moves to Position C, and at Position C the conveyor stops and everything resets. So let's use this simulation software in order to see how this program works. This is how the program looks like in the simulation software. And for demonstration purposes, I'm going to use the light. So I'm going to use the first light to indicate the start process. The second light is for the conveyor and the third light is for the paint. The first light is a yellow light, the second one, which is the one for the conveyor, is a green light, and the third light is red that's indicating the paint. For the start push button I'm going to use the first push button. For Sensor A, B, C, I'm using number two, three, four. So…
