Getting Started with LabVIEW Virtual Instruments Chapter 1. Getting Started with LabVIEW Virtual Instruments By : 粘智硯 40004146

LabVIEW of Definition Through build a user interface, or front panel, with controls and indicators. This controls are knobs, push buttons, dials, and other input LabVIEW programs are called virtual instruments, or VIs, because their appearance and operation imitate physical instruments, such as oscilloscopes and multimeters. LabVIEW contains a comprehensive set of tools for acquiring, analyzing, displaying, and storing data, as well as tools to help you troubleshoot code you write. You can use LabVIEW to communicate with hardware such as data acquisition, vision, and motion control devices

How to Build a Virtual Instrument.(VI) 1. In the Getting Started window, click the New or VI from Template link to display the New dialog box. 2.From the Create New list, select VI. A preview and a brief description of the template VI appear in the Description section. 3. Click the OK button to create a VI from the template. LabVIEW displays two windows: the front panel window and the block diagram window. 4. Examine the front panel window. The user interface, or front panel, appears with a gray background and includes controls and indicators. The title bar of the front panel indicates that this window is the front panel for the Generate and Display VI.

Opening a New VI from a Template

Wiring Objects on the Block Diagram

Running a VI

Modifying a Signal Configure and Formula Dialog Box

Displaying Two Signals on a Graph

Customizing a Knob Control

Customizing a Waveform Graph

Finish the while loop

Summary and Gained knowledge It is my first time to learn the different Program which is LabVIEW ,and through this course I think that LabVIEW is more humane than Power Line Communication. There are following two Example to explain : First : This is because it could take a lot of time for you to finish all the stuff by Power Line Communication. But, if you know LabVIEW which can be of assistance to you and which is also willing to help you, then it can save you lots of time. Second : Because of the Interface of Human Machine is different with the traditional Interface ; LabVIEW use property dialog boxes or shortcut menus to configure how controls and indicators appear or behave on the front panel. The LabVIEW Help contains information about LabVIEW programming concepts, step-by-step instructions for using LabVIEW, and reference information about LabVIEW VIs, functions, palettes, menus, tools, properties, methods, events, dialog boxes, and so on. At final this chapter introduced the keyboard shortcuts that is very useful.

The End Thank you for reading.
