You’ve heard this phrase before: “It’s simple. But nobody said it would be easy.”
And this is exactly one of those cases.
The Honeywell UDC3500 digital controller can support up to four setpoint programs, the ramp/soak profiles used in batch control operations. But after configuring all four profiles, I was stuck on how to select the one I wanted the controller to use.
