I am trying to use a steam table function with PI Datalink and get a -12300 Performance equation error. I am hoping somebody can help me out with the syntax.

**Convert(Steam_PsatT(Convert('TI-1487.PVI', "degC")), "psia")**

I looked for some syntax help in the manuals but did not find much.

Thank you,

dan

Hey Dan,

In DataLink, you're only able to utilize Performance Equations, the steamtables are only available for the Analysis service and not Performance Equations. I know the analysis expressions and performance equation functions have a lot of overlap, particularly with the Tag retrieval functions however not all contained in one are in the other.

Cheers,

Rob
