Such an instrument may employ a transducer to sense changes in a physical parameter such as temperature or pressure, and to convert the sensed information into electrical signals such as voltage or frequency variations. This degree of user-configurability and transparency will change the way engineers build test systems.

When you move the cursor over a VI icon, the Context Help window displays this description and indicates which terminals are required, recommended or optional. With the right software tool, engineers and scientists can efficiently create their own applications by designing and integrating the routines that a particular process requires.

Most of them contain the latest features of the last generation, including audio, a phone book and text messaging capabilities.

This process as shown in Figure 1. We can extend the set of functions easily, limited only by the power of the software used. Labels for expandable subVIs appear in the colored field that surrounds the icon.

I am sure that the textbook will serve as a valuable resource of UG and PG engineering courses for students and faculty using experiential teaching—learning methodology. The terminal turns white to indicate that the connection no longer exists. The block diagram contains this code.

Each node blinks to denote when it is ready to execute. Irrespective of whether it is classical or graphical environment any system with jjerome graphical system design can be looked at as being composed jerlme two parts—the user interface and the underlying code.


The VI shows error if the conditional terminal is unwired. A local variable shares data within a VI; a global variable also shares data, but it shares data with multiple VIs.

Finally, I am greatly indebted to my family—my husband Jerome Benjamin, our daughter Arumika Jerome and our son Jude Prabu Jerome and appreciate their encouragement and loving support. This ensures that your applications labfiew only work well today but that you can easily integrate new technologies in the future. Control labvkew indicator terminals belong to front panel controls and indicators. Front panel and block diagram to display numeric indicator. You can define how and when the application acquires data from the device, how it processes, manipulates and stores the data, and how the results are presented labvifw the user.

With virtual instrumentation, engineers and scientists reduce development time, design higher quality products, and lower their design costs. To use a VI as a subVI, you need to build a connector pane. On the block diagram, you can distinguish read locals or globals from write locals or globals the same way you distinguish controls from indicators.

The concept of auto-indexing is explained in Chapter 5 in detail. Owned label becomes variable labfiew and select whether you want to read or write to the local variable. Neither is any liability assumed by the author and the publisher for any damages or loss to your data or your equipment resulting directly or indirectly from the use of the information or instructions contained herein.

In this example 10 different pictures consists of 10 different actions of a dog at running state is taken for animation.

The dynamic data type stores the information generated joitha acquired by an Express VI.


LabVIEW includes a wide array of built-in visualization tools to present data on the user interface of the virtual instrument as chart, graphs, 2D and 3D visualization.

Modular Programming 61 Figure P3. Types of terminals include control or indicator terminals and node terminals. To access the shortcut menu, right-click the object. A tool is a special operating mode of the mouse cursor. I acknowledge with gratitude Mr. LabVIEW is a compiled language that generates optimized code with execution speeds comparable to compiled C and developes high-performance code.

The remainder of the quotient and remainder function varies from 0 to 9. 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.


The most often- used menu is the object shortcut menu. A new, unnamed project opens, and you can add files to and save the project. Structures on the block diagram are used to repeat blocks of code and to execute code conditionally or in a specific order. 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.

The data you wire to the ejrome of each shift register must be the same type.

Both the count and iteration terminals are bit signed integers. However, if you unwire the optional terminal, the input or output arrow does not appear. You can select an appropriate pattern by right-clicking the connector pane and selecting Patterns from the shortcut menu as shown in Figure 3.
