NATIONAL INSTITUTE OF SCIENCE & TECHNOLOGY VIRTUAL INSTRUMENTATION BIBHU SANTOSH ROUT EI [12] Interfaces of a VI  Front pane: Serves as the user interface.  Block diagram: Contains the graphical source code that defines the functionality of the VI.  Icon and connector pane: Identifies the VI so that you can use the VI in another VI. A VI within another VI is called a sub VI.  A sub VI corresponds to a subroutine in text-based programming languages
