Bi-linear interpolation for AF Tables is now supported in the PI AF 2018 (2.10.0) release. See 'Examples of linear and bilinear interpolation in table lookup data references' topic in the documentation.
Thanks David for the quick and helpful answer. I guess the ball is in my IT dpt now.
- a comment from the IT Dpt @Pierre
using the function: as in the example - we get thrown the following: The expression contains undefined function call INTERPOLATE().
when we use the example referred to in the answer above - by the way in the expression in the example there are too many "end"-parentheses:
your expression: SELECT Velocity FROM Table1 WHERE INTERPOLATE([X Horizontal Position]), @X) AND INTERPOLATE([Y Vertical Position]), @Y)
I count 2"(" and 4")"
David; could you pls. comment on this.
