Hi there,


I'm trying to get a  the maximum 15 minute average of the sum of three tags using PI DataLink.  What I have so far is getting the 15 minute average of 1 tag using:




Somehow I would like to sum all three tags (let's say: Sinusoid1, Sinusoid2, Sinusoid3) before doing the maximum 15 minute rolling average.  I tried using Total('Sinusoid1','Sinusoid2','Sinusoid3') inside the TagAvg function but I get an error... 


Or is there a better way with  PI Datalink?  I don't want to touch PI AF right now.
