Example:
In our example, the ANY pointer refers to a range of values starting at address 16
in DB20. The data structure of the polynomial is fixed and has a set length of 60
bytes.
Note
You can save yourself editing work by using UDT 20 from the "S7-Tech" library.
UDT 20 contains the data structure of the polynomial. You can add up to 4
polynomials in one call by repeating this structure.
Input Data: Table of interpolation points
When cams are created by means of interpolation point tables, the X and Y values
are fetched from a data area in the user program. The interpolation point table
consists of at least one interpolation point (two REAL values). Up to 30
interpolation points can be passed with each call.
