I looked at the program today. It seems to be a very indirect route of getting something done. It's a little hard to follow through the steps. They way it is written appears as if someone was writing a sequencer.
I guess the part that was really throwing me off was the print out that I was describing earlier. The program itself is in ladder logic but what was given to us for a hard copy was the flow chart and boxes.
They claim that is easier to follow through when trouble shooting. The flow chart is ok but it doesn't allow one to a person to track everything back to everything that's required to get things started.
If your given just the rungs of a program that run a motor for example. It is pretty useless if there are other bits that need to become true or false for the motor to run and you don't have the rungs that show what sets the state of those bits.
I hope this is as clear as mud. I think I might have even confused myself.
Thanks.
