Virtual Instruments using LabView by – Jovitha Jerome | Seemant Singh 13BEE –

Another issue that affects the application you have currently built is that the top-level VI does not quit LabVIEW or close the front panel when it is finished executing. Networking support on smaller systems was first introduced in Version 5. Ensure that you have selected a pattern sufficient for the number of controls and indicators you want to assign to the connector pane. Graphical environments are better for nonprogrammers and useful for developing virtual instruments quickly and need to be reconfigured rapidly.

When this node executes, the VI reads the data in the associated front panel control or indicator. A software platform which integrates multiple models of computation minimizes the time to implement specifications into a design. Complete the following steps to set a terminal to required, recommended, or optional.

Labels for expandable subVIs appear in the colored field that surrounds the icon. Without the displays, knobs and switches of a conventional, external box-based instrumentation products, a virtual instrument uses a personal computer for all user interaction and control.

Changing the value of the control does not stop the infinite loop because the value is only read once, before the loop starts. To link controls and indicators to the connector pane, place inputs on the left and outputs on the right to prevent complicated or confusing wiring patterns.

Click the broken Run button to display the Error list window, which lists all the errors. Repetition and Loops 77 4. This function guarantees that the loop execution rate is at least the amount of the input you specify. The produced colors are displayed in the framed Color Box indicator.

As designs iterate through this build-measure- tweak-rebuild process, the designer needs the same measurements again. The default icon can be changed to a custom icon which contains text, images or a combination of both. Includes a summary that outlines important learning points and skills taught in the chapter.

This VI uses a subVI for finding the trigonometric values. To create a stacked shift register, right-click the left terminal and select Add Element from the shortcut menu. Using LabVIEW, you can create test and measurement, data acquisitions, instrument control, datalogging, measurement analysis, and report generation applications.

The benefits that have accelerated test development are beginning to accelerate control and design. To access the shortcut menu, right-click the object. A wait function is placed inside a loop to allow a VI to sleep for a set amount of time.

The computing power of the processors improved by leaps and bounds permitting the development of all these resource intensive techniques. Solution The front panel has three numeric inputs while the block diagram contains compound arithmetic functions as shown in Figures P2.

An introduction is provided to some important LabVIEW tools like signal processing and analysis tools, control design and simulation tools, sound and vibration toolkit, express VI development toolkit, system identification toolkit, data logging and supervisory control tools and embedded module.

You can also right-click an open space on the block diagram to display the Functions palette. An icon is a graphical representation of a VI.

Find the length of the input string and reverse the string. In the front panel, the Picture Ring Indicator is used to display sequence of pictures.

The majority of computer systems use the Microsoft Windows operating system. The block diagram contains this graphical source code. Following are the pictures taken for animation.

Now the picture is jrome in Windows Clipboard. Engineers and scientists can improve functionality through software instead of developing further specific electronics to do a particular job.

What is a default icon and a custom icon? See the flow of data through the block diagram. Verify that the result is equal to the product of x and y. Right-click an open space on the block diagram to display the Functions palette. The front panel and block diagram are shown in Figures P2.

The For Loop executes five times. Two ways of accessing this data include the shift register and the feedback node. The first time you run the VI, the shift register begins with a value of 0, which is the default value for a bit integer. And as companies incorporate innovations to differentiate their products, test systems must quickly adapt to test the new features. Double-click the hatched box which will select the entire icon.

Solution Click continuous run and increment the number to see the even and odd LED glow alternatively.

Otherwise, the VI containing the subVI is broken and will not run. Signal processing and analysis as well as visualization instrumentahion be implemented online while data is being measured and acquired, or while the process is being controlled. Another way is to select the Local Variable from the Structures palette. The basic components of a motion control system and the software for configuration, prototyping and development are explained in Chapter Find logarithmic values for inputs x and y log x and log y.

Various interface standards are used to connect external devices to the computer.
