Summary:
I want to equate a Process Analyst cursor value to a tag. How do I achieve this?

Solution:

This can be done through the use of cicode: 
_ObjectCallMethod(hTrendCursor , "GetValue", hPen, asLocal, Time2, milli, value);

The difficulty is that you need to input the TrendCursor and the Pen, which are different objects into the same function.


INT

FUNCTION

PA_cursor_value(INT PaneNo = 1, INT PenNo = 1, INT CursorNo = 1)

 

    OBJECT hPA;

    OBJECT hCursors;

    OBJECT hTrendCursor;

    OBJECT hPanes;

    OBJECT hPane;

    OBJECT hPens;

    OBJECT hPen;

 

    INT asLocal = 0;

    REAL Time2;

    INT milli;

    STRING value;

 

    //GET PROCESS ANALYST OBJECT

    hPA = ObjectByName("CSV_PA");           //Change for name of your PA Object

 

    //SELECT DESIRED PEN

    hPanes = _ObjectGetProperty(hPA,"Panes");            //Gets all Panes

    hPane = _ObjectCallMethod(hPanes,"get_Item",PaneNo); //Selects Desired pane

    hPens = _ObjectGetProperty(hPane,"Pens");           //Gets all Pens

    hPen = _ObjectCallMethod(hPens,"get_Item",PenNo);   //Selects Desired Pen

 

 

    //SELECT DESIRED TRENDCURSOR

    hCursors = _ObjectGetProperty(hPA,"Cursors");

    hTrendCursor = _ObjectCallMethod(hCursors,"get_Item",Cursor No);//Get desired cursor

 

    //GET CURSOR VALUE BASED ON PEN AND CURSOR

    _ObjectCallMethod(hTrendCursor , "GetValue", hPen, asLocal, Time2, milli, value);

   

    RETURN StrToint(Value);

    //You may want to return as a real

 

END
