Pierre, thanks again, but, really, my purpose is to share information so we can all do a better job.
There is plenty in this world that baffles me. For example, while I understand ladder logic, I couldn't program a PLC to save my life. That's why I came to this board originally, to learn a bit about PLC's.
I have a project coming up in a year or two that involves my hobby and will require a PLC to do the logic. I am dreading dealing with that and am hoping to get some help for the programming. Then, the tables will be turned!!
And anyway, what's that saying "Everything I know, I learned from someone else!" I try to keep that in mind every day.
My advice is to find your specialty and focus on being good at that. I know that's dangerous these days but, if you have to be a generalist, for me, it just isn't very satisfying.
Good luck on finding and getting comfortable with your "specialty", whatever it is!
