VIRTUAL INSTRUMENTATION USING LABVIEW – JOVITHA JEROME – Google Books

When you resize an expandable subVI, the input and output terminals of the subVI appear below the icon. You also can use the wiring tool to click the control or indicator.

Solution The block diagram to find the average of two numbers and convert a section of a VI into a subVI by selecting that portion is shown in Figures P3. The feedback node arrow indicates the direction in which the data flows along the wire. Find the equivalent gray code for a given BCD. In the Context Help window, the labels of required terminals appear bold, recommended terminals appear as plaintext, and optional virhual appear dimmed.

Using LabVIEW, the joviyha can originate exactly the type of virtual instrument needed and programmers can easily view instrrumentation modify data or control inputs. Local variables store data in front panel controls and indicators.

When you click a subpalette icon, the entire palette changes to the subpalette you selected. The Functions palette as shown in Figure 2. The feedback node shown in Figure 4. To use an object on the palettes, click the object jovithx place it on the front panel. The benefits of graphical system design comprise reduced time to market, optimal system scalability, quick design iteration and increased performance at lower cost.

To associate a local variable with a control or indicator, right-click the local instrummentation node and select Select Item from the shortcut menu. Right-click the icon in the upper-right corner of the front panel and select Show Connector from the shortcut menu to display the virttual pane.

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. Third, individual components can be reused in other programs. Use of any product or service name in this book should not be regarded as affecting the validity of any trademark or service mark. To stop the Instrumentatiin immediately if there is no other way to stop the VI.

And as companies incorporate innovations to differentiate their products, test ihstrumentation must quickly adapt to test the new features. Solution The angle is provided as control and the corresponding radians, sin, cos and tan values are displayed.

No part of this book may be reproduced in any form, by mimeograph virfual any other means, without permission in writing from the publisher. With powerful server technology you can offload processor- intensive routines to other machines for faster execution, or create remote monitoring and control applications. By default, subVIs appear as icons on the block diagram.

Creating cluster controls and indicators are dealt with in Chapter 6. Similarly, test system development is evolving towards a modular approach. In fact, the full-featured LabVIEW programming language has the same constructs that traditional languages have such as variables, data types, objects, looping and sequencing structures, as well as error handling. If you add one more element to the left terminal, the value from the last two iterations carry over to the next iteration, with the most recent iteration value stored in the top shift instrumenttion.

This open language takes advantage of existing code; can easily intergrate with legacy systems and incorporate third party software with.

The front panel control function of the existing instrument is duplicated through the computer interface. A connector pane receives data at its input terminals and passes the data to the block diagram code through the front panel controls or receives the results at its output terminals from the front panel indicators.

The primary benefits of apply data acquisition technology to configure virtual instrumentation include costs, size, and flexibility and ease of programming.

A checkmark indicates the terminal setting. After you build joovitha user interface, you can add code using VIs and structures to control the front panel objects. The computing power of the processors improved by leaps and bounds permitting the development of all these resource intensive techniques. Both the count and iteration terminals are bit signed integers.

How to create a subVI from the portion of an available VI? This degree of user-configurability and transparency will change the way engineers build test systems. The numeric data type shown in Figure 2.
