I didn't review the original wiring diagrams to assure that the samples function as they originally did but the criteria is: You can do a quick google of "cougar tail lights" to see videos of how they operate. I've chosen the 1960s Mercury Cougar sequential tail light problem to work with. This sample program shows examples of sequencing machines using cascading timers, counters, manipulating words, multiplication, sequencers, and by gremlins possessing your machine. You will learn the details of how each one works in future lessons. If you don't fully understand each method, that is OK. The purpose of this lessons is to give you a little bit of a primer into the ways of sequencing machine step. But first you will download the Cougar Tail Light RSS file to your PLC. In the next few lessons, you will be learning several methods of sequencing machine steps. The ability to program sequential steps greatly increases both the capabilities of your control system and complicates control system troubleshooting at the same time.
