Trending digital I/O


#1

Why does groov trend digital I/O like this? Is it catching the input as it’s turning on/off? Not on/off long enough? The I/O in question is typically on for a min. of 2 sec. (usually much more) and my trend update interval is 1 sec.

How zoomed in are you?

Digital inputs evaluate to 0.0 or 1.0 for the purposes of trending, and if you’re not zooming in all the way, you’re viewing an averaged result, so you’ll end up seeing something like this.

It’s not a big deal, it’s just odd to open a trend for something that is either on or off and see partial values.
