DataLink filtered archived values

Hello everyone,

I'm having trouble making a filter to retrieve sampled data from some tag.

Let's say I have 2 tags: "tag1" is a digital and returns "False" or "True" as possible values, "tag2" is a Float which is the tag that I want to retrieve data.

I want to get the value of all points in tag2 that occurred in the same moment (timestamp) that tag1 changed from "False" to "True"

I tried using both compressed data and sampled data but neither worked as needed.

Any suggestions?

Thanks in advance.
