How to Use LabVIEW 2014 for Test, Measurement, and Control Applications
LabVIEW 2014 is a systems engineering software that enables you to design, prototype, and deploy applications that require test, measurement, and control with rapid access to hardware and data insights. LabVIEW 2014 is available in different editions, such as Base, Full, Professional, and 64-bit, depending on your needs and preferences. In this article, we will show you how to use LabVIEW 2014 for various tasks and projects.
The first step is to download and install LabVIEW 2014 on your computer. You can use the following link to access the download page and choose the edition that suits you best. You will need a valid license to activate the software after installation. You can also download additional modules and toolkits that extend the functionality of LabVIEW 2014, such as the MathScript RT Module, the FPGA Module, or the Advanced Signal Processing Toolkit.
Create a New Project
Once you have installed LabVIEW 2014, you can launch it from the Start menu or the desktop shortcut. You will see the Getting Started window, where you can create a new project or open an existing one. A project is a collection of files and settings that define your application. To create a new project, click on File > New Project. You will see the Create Project dialog box, where you can choose a template or a sample project to start with. For example, you can choose a Blank Project, a DAQmx Project, or a FPGA Project. Click on Next to continue.
Add Files and Folders to Your Project
After you create a new project, you will see the Project Explorer window, where you can manage your project files and settings. You can add files and folders to your project by right-clicking on the project name and selecting Add > File or Add > Folder. You can also drag and drop files and folders from Windows Explorer to the Project Explorer window. Some of the files that you can add to your project are:
VIs (virtual instruments) - graphical programs that define the functionality of your application.
Controls - graphical user interface elements that allow users to interact with your application.
Indicators - graphical user interface elements that display data or status information from your application.
SubVIs - VIs that are used as subroutines within other VIs.
Libraries - collections of VIs, controls, indicators, and other files that share common functionality or purpose.
Documents - text files, images, videos, or other files that are related to your project.
Design Your User Interface
To design your user interface, you need to use the Front Panel window of your VI. The Front Panel window is where you place controls and indicators that allow users to interact with your application. To open the Front Panel window of a VI, double-click on its icon in the Project Explorer window or right-click on it and select Open Front Panel. You will see a blank window with a toolbar at the top. You can use the Controls Palette to access various controls and indicators that you can place on the Front Panel window by dragging and dropping them. You can also use the Properties dialog box to customize the appearance and behavior of each control and indicator by right-clicking on it and selecting Properties.
Program Your Logic
To program your logic, you need to use the Block Diagram window of your VI. The Block Diagram window is where you create graphical code that defines the functionality of your application. To open the Block Diagram window of a VI, click on the Window menu in the Front Panel window and select Show Block Diagram or press Ctrl+E. You will see a blank window with a toolbar at the top. You can use the Functions Palette to access various functions and structures that you can place on the Block Diagram window by dragging and dropping them. You can also use wires to connect different functions and structures to pass data between them. You can use constants, variables, arrays, clusters, or other data types to store and manipulate data in your code.
