In previous lessons we’ve discussed instructions that are in the folder called shift and rotate. In a continuation of that training, this lesson goes into some more detail about the shift instruction. One useful application for this shift instruction is to create different patterns of turning on and off a set of outputs. We have two start switches and a stop switch that we will use to turn on 16 lamps that are wired on consecutive outputs. We will need to replace our 8 point output card with a 16 point and will show you how to accomplish this task. We discuss how the shift will fire the different outputs in which order. Open up this lesson and let’s get started.

In the previous lesson we’ve discussed the sequence in which the lamps will light using a shift instruction. In this lesson we are going to write the logic to make the lamps turn on sequentially as well as turn all of them off at the same time with the press of the stop switch. After we have writ...
In a continuation of instruction training for the shift instruction located in the folder called shift and rotate, this lesson continues from the previous lesson where we had written some code but found that it didn’t quite function as we wanted. We pressed the S1 button and the first lamp turned...
In this lesson we continue working with the shift instruction located in the folder called shift and rotate. In the previous lesson we found a solution to our problem that was turning on the first lamp as we expected however, the remaining lamps turned on at once with the press of the S2 switch. ...
