Is it possible to get historical data for a defined period for multiple PI points using Web API? What would be the query format for this?
I felt your question would be worth a new question and branched it from the other one.
Let's use our public PI Web API endpoint to develop the answer to your question. The first thing to do, after picking up the login information, is to lookup some WebID's, so I am searching for PI Points 'SINUSOID'.
Let's copy the WebID: P0W6Wlk0_Utku9vWTvxg45oAAQAAAAUElTUlYxXFNJTlVTT0lE
Now we modify the query and look for 'CDT158'.
The search yields 2 results, so let's pick the WebID of 'CDT158': P0W6Wlk0_Utku9vWTvxg45oAAwAAAAUElTUlYxXENEVDE1OA
The Streamset controller allows queries to multiple unrelated data items at once. Because there are at least 2 options, I suggest using GetValuesAdHoc.
