Hello everyone,

I am trying to use PI Datalink for some excel based analysis.

Lets assume I have three tags: Tag1, Tag2 and Tag3

I want to list all time stamps within the last 90 days when:

d( Tag2 > (Tag1 + Tag3)) / dt

Which basically means I am looking for all the event times in the last 90 days when Tag2 became bigger than the sum of Tag1 and Tag3 .

Is there a way to solve this with PI Datalink?

Thank you all!

Stefan

Hi Stefan,

Please use filter expression option in available in Datalink to apply the formula. In filter expression text box you can input the tag name and formula to compare with other tags.
