In the previous lesson, I completed the PLC program for the first interruption caused by sensor 1 and tested it in the online mode as well to make sure that everything works within my expectations.
As I promised in part 3 of this video series, I'm going to start writing the PLC program for the second interruption which is caused by sensor 2.
In the previous lesson, I wrote a PLC program for the second interruption based on diagram 2. In this lesson, we're going to test the program in the online mode and then make the necessary changes to ensure that everything is working as we want it to.
We have been playing around with this assembly line code for several lessons and have been informed by a RealPars student of a bug that we need to address. To refresh your memory, this code has a start and stop switch, 2 conveyor belts, a motor for each belt, 2 photo-eye sensors, and a jaw type c...
Now that you’ve come back to the video, what did you do? Could you fix the bug so that no one can run the motor by just passing their hands in front of sensor 2? If you have, congratulations! But if you haven’t, don’t worry, you’re going to learn that in this video.
