Function Tree Hierarchy

The function tree defines the relationship between each function panel. Users think in terms of high-level application operations such as Initialize, Configure, Measure, and so on. Group the functions in the function tree accordingly. Make function trees from similar instruments look similar.

For example, the following figure shows the Fluke 45 instrument driver function tree.

The functions are easy to understand, and the instrument driver user can immediately incorporate them into an application program. Develop your function tree with an application in mind and place the functions in the natural order in which they will be used. Again, keep your function tree consistent with others in LabWindows/CVI. Refer to the Using LabWindows/CVI»Function Tree Editor topic of the LabWindows/CVI Help for more information on editing function trees.
