TABLE OF CONTENTS Learning Objectives. On completion of this chapter the reader will have a knowledge on:
Programming Techniques
Front Panel and Block Diagram of Virtual Instruments
LabVIEW Environment and its Menus
Palletes of LabVIEW
Data Flow Programming
G Programming Concepts
Creating and Saving Vis
Wiring, Editing, and Debugging VIs
Creating Sub VIs
LabVIEW programs are called virtual instruments, or VIs, because their appearance and operation imitate physical instruments, such as oscilloscopes and millimeters. LabVIEW contains a comprehensive set of tools for acquiring, analyzing, displaying, and storing data, as well as tools to troubleshoot the code. LabVIEW VIs contain three components the front panel, the block diagram, and the icon and connector pane. This section describes the front panel and the block diagram along with the controls and indicators used to create the user interface and functions to create the block diagram. Dataflow programming and G programming are also discussed along with the data types and operations that can be performed in LabVIEW. The menus available on the two windows front panel and block diagram are illustrated to enable the user understand the basic operation of LabVIEW. The section also focuses on creating a VI, subVI along with the libraries available.
Virtual Instruments are front panel and block diagram. The front panel or user interface is built with controls and indicators. Controls are knobs, push buttons, dials, and other input devices. Indicators are graphs, LEDs, and other displays. After...
