Structured Text

Hi All,

I've used st here and there but have never had a problem like it and can't seem to figure out what i did wrong. Here's the script.

Target_Point[0] := ( Xco * Pco * 0.25 * (5700-CR)) + (Xm * Pm * 0.75 * (5700 - CR)) + ( CR * Protein_Cream);

and yes I've created all tag names for the abbreviations and so forth. Is my synthax wrong? To long to compute? Please help and thank you!!!

Can you post the actual error the compiler is giving you?

5700 should be 5700.0

what is the error?

are all of the tags REALs? Is target point an array[0..?] of REAL (not [1..?])

That's a good catch V0N. It's been a while, but I believe that in Codesys you have to explicitly change the datatypes. For example, you may need some "DINT_TO_REAL()" or "REAL_TO_DINT()" functions in there (or something along those lines).

I would recommend that you post the exact error as well as your variable declarations.
