HelloI have a Scripting question on Wonderware System Platform.I was needing to know how to write a script to add two values together.for example i have two flow meters and i what to write a script that basicly says take flow meter value #1 (add) flow meter value #2 = flow_total and then use this flow_total tag for my trending.I dont know if something like this would work (Flow_Total=Flow#1+flow#2)I can do this fine in an expression when totaling values on a tag, but I need to do this for trending.Trend wont let me use two tags Thanks for the help

Write your script then put Flow_Total in as a UDA then go to extensions and check on historical extension for the attribute Flow_Total and then you will be able to trend it.
