To debug the Facade VI, open the front panel of a VI, right-click the XControl, and select Advanced»Show Block Diagram from the shortcut menu. Use breakpoints, single-stepping, and probes to debug the Facade VI just as you would debug any VI.
To debug abilities, properties or methods, set a breakpoint in the ability, property, or method VI. When LabVIEW calls the VI, LabVIEW pauses execution at the breakpoint and displays the block diagram of the VI. Use single-stepping and probes to debug the VI just as you would debug any VI.
