Then, of course, remember
Remember... that word looks familiar. I wonder where I, I, what were we talking about?
Thanks. It actually crossed my mind something like that might work, especially at the HMI side. But I am really leaning towards discrete logic after all. Anything using real I/O has a tendency to need addresses swapped around at some point and doing that when I have a FOR-NEXT doing the scaling (never mind PID) suddenly becomes nightmarish.
