We have been working, for a few lessons, on a PLC shift instruction to turn on and off some lamps, in different sequential patterns. We will continue to modify our program from the previous lesson, where we worked with the logic such that we wanted to turn on the first lamp and after a delay, turn it off. We then want the next lamp to turn on and then off, repeating this pattern until all lamps have cycled, from top to bottom, but we want to leave the last lamp on. We will then want the pattern to reverse and turn on and off the lamps from bottom to top. Let’s continue working with this program to complete the task.

We have been writing some code that will turn on and then of some lamps, one at a time, beginning from the top of a display to the bottom. We want to start this sequence with press of a button. After the lamps sequence to the bottom and prior to the last lamp turning off, we want the sequence to ...
We created a series a while back called Turning on PLC Outputs in Sequential Order and that series had 9 parts. We have again opened up that series to address the many questions and comments among the RealPars students. This was an extensive series that walked you through the programming of turni...
This is a continuation of the series about Turning on PLC Outputs in Sequential Order. In the previous lesson, we refreshed your memory on the logic that we had written as well as the general idea of how we want the program to function. In this lesson, we are going to delete a little bit of code ...
