2017 / May 2017; 7 months ago ( 2017-05):, analysis and, design Website Laboratory Virtual Instrument Engineering Workbench ( LabVIEW): 3 is a system-design platform and development environment for a from. The graphical language is named 'G'; not to be confused with. Originally released for the Apple in 1986, LabVIEW is commonly used for, and industrial on a variety of (OSs), including, various versions of, and.
The latest versions of LabVIEW are LabVIEW 2017 and LabVIEW NXG 1.0, released in May 2017. Contents. Dataflow programming The programming paradigm used in LabVIEW, sometimes called G, is based on data availability. If there is enough data available to a subVI or function that subVI or function will execute. Execution flow is determined by the structure of a graphical block diagram (the LabVIEW-source code) on which the programmer connects different function-nodes by drawing wires.
These wires propagate variables and any node can execute as soon as all its input data become available. Since this might be the case for multiple nodes simultaneously, LabVIEW can execute inherently in parallel.: 1–2 and hardware is exploited automatically by the built-in scheduler, which multiple OS threads over the nodes ready for execution.
Graphical programming LabVIEW integrates the creation of user interfaces (termed front panels) into the development cycle. LabVIEW programs-subroutines are termed virtual instruments (VIs). Each VI has three components: a block diagram, a front panel, and a connector panel. The last is used to represent the VI in the block diagrams of other, calling VIs. The front panel is built using controls and indicators.
Controls are inputs: they allow a user to supply information to the VI. Indicators are outputs: they indicate, or display, the results based on the inputs given to the VI. The back panel, which is a block diagram, contains the graphical source code.
All of the objects placed on the front panel will appear on the back panel as terminals. The back panel also contains structures and functions which perform operations on controls and supply data to indicators. The structures and functions are found on the Functions palette and can be placed on the back panel. Collectively controls, indicators, structures, and functions will be referred to as nodes.
Nodes are connected to one another using wires, e.g., two controls and an indicator can be wired to the addition function so that the indicator displays the sum of the two controls. Thus a virtual instrument can be run as either a program, with the front panel serving as a user interface, or, when dropped as a node onto the block diagram, the front panel defines the inputs and outputs for the node through the connector pane. This implies each VI can be easily tested before being embedded as a subroutine into a larger program. The graphical approach also allows nonprogrammers to build programs by dragging and dropping virtual representations of lab equipment with which they are already familiar. The LabVIEW programming environment, with the included examples and documentation, makes it simple to create small applications. This is a benefit on one side, but there is also a certain danger of underestimating the expertise needed for high-quality G programming. For complex algorithms or large-scale code, it is important that a programmer possess an extensive knowledge of the special LabVIEW syntax and the topology of its memory management.
The most advanced LabVIEW development systems offer the ability to build stand-alone applications. Furthermore, it is possible to create distributed applications, which communicate by a, and are thus easier to implement due to the inherently parallel nature of G. Widely-accepted design patterns Applications in LabVIEW are usually designed using well-known architectures, known as. The most common design patterns for graphical LabVIEW applications are listed in the table below. Jeffrey., Travis, (2006). Upper Saddle River, NJ: Prentice Hall.
