Introduction to LabVIEW, This chapter provides an overview of the LabVIEW development. environment, For information about system configuration requirements see Appendix A. System Requirements Refer to the LabVIEW 5 1 Addendum for installation. instructions,What Is LabVIEW, Italicized text denotes LabVIEW Laboratory Virtual Instrument Engineering Workbench is a. a glossary term development environment based on the graphical programming. language G LabVIEW is integrated fully for communication with. hardware such as GPIB VXI PXI RS 232 RS 485 and plug in data. acquisition boards LabVIEW also has built in libraries for using software. standards such as TCP IP Networking and ActiveX, Using LabVIEW you can create 32 bit compiled programs that give you.
the fast execution speeds needed for custom data acquisition test and. measurement solutions You also can create stand alone executables. because LabVIEW is a true 32 bit compiler, You can use LabVIEW with little programming experience LabVIEW uses. terminology icons and ideas familiar to technicians scientists and. engineers and relies on graphical symbols rather than textual language to. describe programming actions, National Instruments Corporation 1 1 LabVIEW QuickStart Guide. Chapter 1 Introduction to LabVIEW, Programs in LabVIEW for real world applications can vary from the. simple to the powerful as illustrated in the following graphic. LabVIEW contains comprehensive libraries for data collection analysis. presentation and storage LabVIEW also includes traditional program. development tools You can set breakpoints animate program execution to. see how the program executes and single step through the program to. make debugging and program development easier, LabVIEW also provides numerous mechanisms for connecting to external. code or software through DLLs shared libraries ActiveX and more In. addition numerous add on toolkits are available for a variety of application. Why Should I Use LabVIEW, LabVIEW empowers you to build your own solutions for scientific and.
engineering systems LabVIEW gives you the flexibility and performance. of a powerful programming language without the associated difficulty and. complexity, LabVIEW has given thousands of successful users a faster way to program. instrumentation and data acquisition systems By using LabVIEW to. LabVIEW QuickStart Guide 1 2 National Instruments Corporation. Chapter 1 Introduction to LabVIEW, prototype design test and implement your instrument systems you can. reduce system development time and increase productivity by a factor. of 4 to 10, LabVIEW also gives you the benefits of a large installed user base. years of product feedback and powerful add on tools Finally the. National Instruments user network and technical support ensure. the successful development of your solutions,How Does LabVIEW Work. All LabVIEW programs or virtual instruments VIs have a front panel. and a block diagram The palettes in LabVIEW contain the options you use. to create and modify your VI This section overviews the LabVIEW front. panel block diagram and palettes It also explains the dataflow model for. program execution that LabVIEW follows,Front Panel.
The front panel is the graphical user interface of your LabVIEW VI This. interface collects user input and displays program output The front panel. can contain knobs push buttons graphs and other controls and indicators. 1 A control input,2 An indicator output, National Instruments Corporation 1 3 LabVIEW QuickStart Guide. Chapter 1 Introduction to LabVIEW,Block Diagram, The block diagram contains the graphical source code of your VI In the. block diagram you program your VI to control and perform functions on. the inputs and outputs you created on the front panel. The block diagram can include functions and structures from the built in. LabVIEW VI libraries It also can include terminals that are associated. with controls and indicators created on the front panel. 1 A function,2 A structure,3 Terminals from the front panel. LabVIEW QuickStart Guide 1 4 National Instruments Corporation. Chapter 1 Introduction to LabVIEW, LabVIEW palettes give you the options you need to create and edit your. front panel and block diagram,Tools Palette, You use the Tools palette in both the front panel and the block diagram The.
Tools palette contains the tools you use to edit and debug front panel and. block diagram objects,Controls Palette, You use the Controls palette in the front panel The Controls palette. contains the front panel controls and indicators you use to create the user. National Instruments Corporation 1 5 LabVIEW QuickStart Guide. Chapter 1 Introduction to LabVIEW,Functions Palette. You use the Functions palette in the block diagram The Functions palette. contains the objects you use to program your VI such as arithmetic. instrument I O file I O and data acquisition operations. LabVIEW VIs follow a dataflow model for program execution The block. diagram consists of nodes such as VIs structures and terminals from the. front panel These nodes are connected by wires which define the flow of. data through the program The execution of a node occurs when all its. inputs are available When a node finishes executing it releases all its. outputs to the next node in the dataflow path, LabVIEW QuickStart Guide 1 6 National Instruments Corporation. Chapter 1 Introduction to LabVIEW,Where Do I Start. If you are new to LabVIEW the LabVIEW Online Tutorial and the. LabVIEW QuickStart Guide help you get started quickly The LabVIEW.
