Count Number of Changes in String Tag value
Forum / Questions & Answers
We are doing a thruput improvement project and trying to find a way to calculate how many serialized units move thru our workcells. The most robust signal we have to track this with currently is a string tag for the serialID of each unit, but I'm having trouble figuring out how to use the built-in Calculation functions to determine this accurately.
I'm hoping to figure out something that behaves like NumberOfTransitions does for a Bool tag, but for a string tag.
We want to build a dashboard once we can figure this out, to track each workcell's thruput by hour and a rollup for the area.
Thanks in advance for any ideas.

Hi ,
Would the Count aggregate work in this case? It simply counts the good raw values in an interval.
