I'm configuring a P1-540 and a C-More EA3 for a CIP skid in a brewery. I've created an "Automatic" screen, and a "Manual" screen.
I have rungs for manual operation - pretty basic - NOE switches, with Toggle coil outputs (2, both for the indicator and for the various devices). One rung per switch, one subrung on each for the indicator. Works great. As soon as I enable my "automatic mode" rung (there's many subrungs, controlling many various devices based on time, temp, various DI, etc), whichever rung is on the bottom, wins.
What's best practice for when you want to control an output in a couple different ways (like on a manual and an automatic screen?).
Thanks in advance
