Hello,
I've used PI in a previous job, but it's been about ten years... My current company just implemented a PI system, and I seem to have forgotten just about everything I used to know about it.
I'm looking for an efficient way to return, for a given time frame, for each time a tag's value goes from "Off" to "On", how long it stayed in the "On" state. I guess I'm envisioning using DataLink and having two columns - one with a timestamp and one with the length of time in the "On" state, or just one column with the length of time. I need to get the info for a few months of jistorical data, so creating new PE tags to facilitate this isn't a good option. Any help is appreciated.
Thanks,
Jake
