- [Instructor] In this example, I'm going to use sequencer output instruction to control different outputs and develop the ladder of program for it. In this operation, a stop push button is used to start and move through the process, to turn on two motors and three pilot lights in a specific sequence. For this process, step one, all is off. Step two, motor one and motor two are on. Step three, red and green pilot lights are on. And step four, red and yellow pilot lights are on. Remember that the sequencer goes back to step one at each cycle completion. Note that all examples are used to demonstrate the operation of the instruction. Any live design needs to take into account all the specific devices and their behavior within the system. For example, motors need time to speed up and time to stop so you cannot physically turn them on or off instantly. And different motors behave differently. So keep that in mind when you design…
