I’ve got my beta copy of DeltaV version 11 and so of course, I’m looking for all the cool things that didn’t get mentioned at Emerson Exchange in Orlando. But first, a little disclaimer – I’m working with beta software, so YMMV!
First up is the Signal Characterization tab of a DI CHARM. The tab magically appears when you select a CHARM class of Discrete Input.
While the De-Bounce Filter caught my eye, it’s the Output Filter that holds some interesting promise for new, innovative control applications. A quick look at the Help associated with the dropdown reveals:
The Extend sounds like a timed pulse – when the input triggers, the output (what your DI or DC function block would see) latches in for a configured amount of time, regardless of how the input changes.
The Delays sound like they’ll take care of chattering inputs – stay tuned for an explanation of the Delay versus the Delay On/Off. Looks like BOL needs an update.
Edge triggering at the CHARM? I’ve already started dreaming and scheming how to exploit this new feature.
