LabVIEW is a development You should take the time learning something about it and where you can find more information. This chapter explains the basic concepts in LabVIEW.FAQs About LabVIEW We give here a brief overview of what LabVIEW is, why O MAX – Measurement and Automation Explorerįor more information about LabVIEW, visit my Blog: O More detail about Control and Simulation Toolkit in later chapter Working with Projects using Project Explorerĭeployment: Building Executable Applications (.exe) O Palettes: Control Palette, Functions Palette, Tools Palette This document introducing the following themes: The DAQmxBase driver is available for LabVIEW on Windows, Mac OS X and Linux Mainly of G-coded components with only a few register calls through NI Measurement Hardware DDK (Driverĭevelopment Kit) functions, provides platform independent hardware access to numerous data acquisition and A new hardware driver topology (DAQmxBase), which consists The sales pitch of National Instruments is, therefore, that even people with limitedĬoding experience can write programs and deploy test solutions in a reduced time frame when compared to Offer standard software interfaces to communicate with hardware devices. These present themselves as graphical nodes. Drivers and abstraction layers for many different types of instruments and busesĪre included or are available for inclusion. One benefit of LabVIEW over other development environments is the extensive support for accessing Furthermore, it is possible to create distributed applications, which communicate by aĬlient/server scheme, and are therefore easier to implement due to the inherently parallel nature of G-code. The most advanced LabVIEW development systems offer the possibility of building stand-aloneĪpplications. Programmer possess an extensive knowledge of the special LabVIEW syntax and the topology of its memory For complex algorithms or large-scale code, it is important that the This is a benefit on one side, but there is also a certain danger of underestimating the expertise needed for The LabVIEW programmingĮnvironment, with the included examples and the documentation, makes it simple to create small applications. Virtual representations of lab equipment with which they are already familiar. The graphical approach also allows non-programmers to build programs simply by dragging and dropping ![]() This implies each VI can be easily tested before being embedded as a subroutine into a Instrument can either be run as a program, with the front panel serving as a user interface, or, when droppedĪs a node onto the block diagram, the front panel defines the inputs and outputs for the given node through However, the front panel can also serve as a programmatic interface. Controls and indicators on the front panel allow an operator to input data into or extract data from a The last is used to represent the VI in the block diagrams of other, calling Each VI has three components: a block diagram, aįront panel, and a connector panel. Programs/subroutines are called virtual instruments (VIs). LabVIEW ties the creation of user interfaces (called front panels) into the development cycle. ![]() Multi-processing and multi-threading hardware isĪutomatically exploited by the built-in scheduler, which multiplexes multiple OS threads over the nodes ready Simultaneously, G is inherently capable of parallel execution. Since this might be the case for multiple nodes Node can execute as soon as all its input data become available. Programmer connects different function-nodes by drawing wires. The programming language used in LabVIEW, also referred to as G, is a dataflow programming language.Įxecution is determined by the structure of a graphical block diagram (the LV-source code) on which the This paper is part of a series with LabVIEW papers:ĭatalogging and Supervisory Control in LabVIEWĮach paper may be used independently of each other. Visit National Instruments at The code files have the extension “.vi”, which is an abbreviation for “Virtual Instrument”. The latest version of LabVIEW is version LabVIEW 2009, released inĪugust 2009. Instrument control, and industrial automation on a variety of platforms including Microsoft Windows, variousįlavors of UNIX, Linux, and Mac OS X. ![]() Originally released for the Apple Macintosh in 1986, LabVIEW is commonly used for data acquisition, LabVIEW (short for Laboratory Virtual Instrumentation Engineering Workbench) is a platform and developmentĮnvironment for a visual programming language from National Instruments. 14.1 10 functions you need to know about. ![]()
