“…Every VI consists of two main components, the graphical user interface that is named front panel; and the graphical code that implements the functionality of the VI, called block diagram. Once a VI is created and saved, it can be used as a subVI in the block diagram of another VI, acting as a subroutine (Gan & Kuo, 2007;Oussalah & Djezzar, 2010;Sumathi & Surekha, 2007). The front panel contains objects known as controls and indicators.…”
