I am just starting out with PLC programming and would like to ask for help. I have a machine that welds a clip onto a part that already has a nut on it. On this fixture I have a sensor looking for the nut to be on the part. Also I have another sensor to make sure the clip is in the fixture and lastly I have a sensor that makes sure there is only one clip under the part.
Right now if any of these sensors do not turn on the welder will not weld. The problem comes in when one of the sensors becomes shorted on all the time because of weld splatter. The operator will continue to weld parts sometimes without the clip being in place.
I want to use a PLC to make sure each of the three sensors turns on and off with each stroke of the weld cylinder. I've mounted a sensor on the cylinder so I am able to tell when it moves.
I have an Allen Bradley Pico to work with and I've read some of the tutorial. I sure would like a little help getting started.
Thanks,
Dale
