LabVIEW, abbreviate for Class Basic Apparatus Engineering Workbench, is a programming ambiance in which you actualize programs appliance a graphical characters (connecting anatomic nodes via affairs through which abstracts flows); in this regard, it differs from acceptable programming languages like C, C , or Java, in which you affairs with text. However, LabVIEW is abundant added than a programming language. It is an alternate affairs development and beheading arrangement advised for people, like scientists and engineers, who charge to affairs as allotment of their jobs. The LabVIEW development ambiance works on computers active Windows, Mac OS X, or Linux. LabVIEW can actualize programs that run on those platforms, as able-bodied as Microsoft Pocket PC, Microsoft Windows CE, Palm OS, and a arrangement of anchored platforms, including Field Programmable Gate Arrays (FPGAs), Digital Arresting Processors (DSPs), and microprocessors.
Using the absolute able graphical programming accent that abounding LabVIEW users affectionately alarm “G” (for graphical), LabVIEW can access your abundance by orders of magnitude. Programs that booty weeks or months to address appliance accepted programming languages can be completed in hours appliance LabVIEW because it is accurately advised to booty measurements, assay data, and present after-effects to the user. And because LabVIEW has such a able graphical user interface and is so accessible to affairs with, it is additionally ideal for simulations, presentation of ideas, accepted programming, or alike teaching basal programming concepts.
LabVIEW offers added adaptability than accepted class instruments because it is software-based. You, not the apparatus manufacturer, ascertain apparatus functionality. Your computer, constituent hardware, and LabVIEW comprise a absolutely configurable basic apparatus to achieve your tasks. Appliance LabVIEW, you can actualize absolutely the blazon of basic apparatus you need, aback you charge it, at a atom of the amount of acceptable instruments. Aback your needs change, you can adapt your basic apparatus in moments.
LabVIEW tries to achieve your activity as hassle-free as possible. It has all-encompassing libraries of functions and subroutines to advice you with best programming tasks, afterwards the fuss of pointers, anamnesis allocation, and added cabalistic programming problems begin in accepted programming languages. LabVIEW additionally contains application-specific libraries of cipher for abstracts accretion (DAQ), Accepted Purpose Interface Bus (GPIB), and consecutive apparatus control, abstracts analysis, abstracts presentation, abstracts storage, and advice over the Internet. The Assay Library contains a aggregation of advantageous functions, including arresting generation, arresting processing, filters, windows, statistics, regression, beeline algebra, and arrangement arithmetic.

Because of LabVIEW’s graphical nature, it is inherently a abstracts presentation package. Achievement appears in any anatomy you desire. Charts, graphs, and user-defined cartoon comprise aloof a atom of accessible achievement options. This book will actualization you how to present abstracts in all of these forms.
LabVIEW’s programs are carriageable beyond platforms, so you can address a affairs on a Macintosh and again amount and run it on a Windows apparatus afterwards alteration a affair in best applications. You will acquisition LabVIEW applications convalescent operations in any cardinal of industries, from every affectionate of engineering and action ascendancy to biology, farming, psychology, chemistry, physics, teaching, and abounding others.
The LabVIEW affairs development ambiance is altered from accepted C or Java development systems in one important respect: While added programming systems use text-based languages to actualize curve of code, LabVIEW uses a graphical programming language, generally alleged “G,” to actualize programs in a aesthetic anatomy alleged a block diagram.
Graphical programming eliminates a lot of the syntactical capacity associated with text-based languages, such as area to put your semicolons and coiled braces. (If you don’t apperceive how text-based languages use these, don’t worry. With LabVIEW, you don’t charge to know!)
Graphical programming allows you to apply on the breeze of abstracts aural your application, because its simple syntax doesn’t abstruse what the affairs is doing. Figures 1.2 and 1.3 actualization a simple LabVIEW user interface and the cipher abaft it.
LabVIEW uses terminology, icons, and account accustomed to scientists and engineers. It relies on graphical syms rather than textual accent to ascertain a program’s actions. Its beheading is based on the assumption of dataflow, in which functions assassinate alone afterwards accepting the all-important data. Because of these features, you can apprentice LabVIEW alike if you accept little or no programming experience. However, you will acquisition that a ability of programming fundamentals is absolute helpful.
A LabVIEW affairs consists of one or added basic instruments (VIs). Basic instruments are alleged such because their actualization and operation generally imitate absolute concrete instruments. However, abaft the scenes, they are akin to capital programs, functions, and subroutines from accepted programming languages like C or Basic. Hereafter, we will accredit to a LabVIEW affairs as a “VI” (pronounced “vee eye,” NOT the Roman character six, as we’ve heard some bodies say). Also, be acquainted that a LabVIEW affairs is consistently alleged a VI, whether its actualization or action relates to an absolute apparatus or not.
A VI has three capital parts: a advanced panel, a block diagram, and an icon.
Virtual instruments are hierarchical and modular. You can use them as top-level programs or subprograms. With this architecture, LabVIEW promotes the abstraction of modular programming. First, you bisect an appliance into a alternation of simple subtasks. Next, you body a VI to achieve anniversary subtask and again amalgamate those VIs on a top-level block diagram to complete the beyond task.
Modular programming is a additional because you can assassinate anniversary subVI by itself, which facilitates debugging. Furthermore, abounding low-level subVIs generally accomplish tasks accepted to several applications and can be acclimated apart by anniversary alone application.
Just so you can accumulate things straight, we’ve listed a few accepted LabVIEW agreement with their accepted programming equivalents in Table 1.1.
