How to Explain PROFINET to Your Mom

You’re at a party and someone asks you what you do. I actually used to fear the question, but now I have a stock answer: “I evangelize an industrial automation communication technology.” Eyes immediately glaze over; then we can talk about the weather or sports. But once, a grandniece expressed (feigned?) continued interest. So instead…
