I´m unsing datalink and I´m trying to find a solution.
What i was looking for is: I have a tag that has the flow rate "ft20"
But it goes to diferente tanks, the direction is alocated in another tag "Direction"
I need to calculate how much during a day, I send to each tank.
I was trying to use calculate Data with filter expression, using '\\server\\Direction' = name of my tank.
But it gave me, invalid expression
Thank you for ur support
Thanks for posting on PI Square.
Based on the information, my first inclination would be that you have a syntax error. I think your syntax for your filter expression should be '\\server\Direction' = name of my tank.
I think you have an extra '\' following the server name. Please give that a shot.
