all of our "Normally Closed" signals drop to 0 and valves start to close.
Thank you Ken. Now I just need to figure out why we're losing comms (Or power?) momentarily. I will look into our battery backup/power supply for this rack. Or maybe the backplane is flaky?
I am also trying to deal with the problem programmatically, but this is more of a band-aid.
Thanks for your help everyone!
