MECH430 Instrumentation and Measurements Najib Metni – Ali Ammouri – Elie Kfouri Module 1 Summer 2008 Page 1 Introduction to National Instrument’s LabVIEW For Loops - Formula Nodes - Plots WHY LEARNING LABVIEW? LabVIEW is a very powerful graphical programming language for instrumentation and control applications. It is specifically designed to take measurements, analyze data, and present results in a very efficient way. It has a versatile graphical user interface and a vast library of functions for a wide range of applications. It is easy to program with, and may be used to solve a wide range of engineering problems. LEARNING OBJECTIVES o Navigate the LabVIEW graphical programming language environment. o Create a VI code to perform simple math operations and use of formula node. o Use For and While Loops. o Display results on a Waveform Charts and Graphs. RESOURCES o Lab Modules on Moodle o LabVIEW 8.2 tutorial on Moodle o National instrument website: http://www.ni.com VOCABULARY LabVIEW – Laboratory Virtual Instrument Engineering Workbench (LabVIEW) is a graphical programming language that uses icons instead of lines of text to create programs. Virtual Instrument – Programs created using LabVIEW are called virtual instruments (VIs). Front Panel – The interactive user interface of a VI that contains controls and indicators. Controls Simulate typical INPUT devices such as knobs and switches Indicators Simulate OUTPUT displays that show the data that the program requires or generates. Block Diagram Holds the graphical source code of a LabVIEW VI. Terminals – Entry and exit ports that exchange information between the front panel and block diagram Nodes Program execution element. Wires Data paths between source and destination terminals. Icon/Connector Pane
