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
