Textual programming requires the programmers to be reasonably proficient in the programming language. A single computer equipped with LabVIEW is used for countless applications and purposes—it is a versatile product. Developments of various interfacing standards lead to a massive reduction in development effort.

To run a VI and it appears as a solid white arrow. When this node executes, the VI reads the data in the associated front panel control or indicator. You can add more than one shift register to a loop.

Repetition and loop are used to perform an action frequently with variations in the details each time. To access the shortcut menu right-click the object and change the look or behavior of instrumenhation panel and block diagram objects.

LabVIEW consists of two wait functions. In order to deploy the application, you first prepare the code, create an Application Exe Build Specification, and then create an Installer Build Specification. To link controls and indicators to the connector instrumentationn, place inputs on the left and outputs on the right to prevent complicated or confusing wiring patterns.

Right-click the terminal you want to disconnect on the connector pane and select Disconnect This Terminal from the shortcut menu.


With virtual instrumentation, engineers and scientists reduce development time, design higher quality products, and lower their design costs.

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. A few industrial GSD applications like a material handling system, plastic injection molding system and a semiconductor production control system are discussed.


Modular Programming 53 Step 3: Virtual instrumentation software can combine one development environment for both desktop and real-time systems using cross-platform compiled technology; you can capitalize on the built-in Web servers and easy-to-use networking functionality of desktop software and target it to real-time and embedded systems.

Navigate to and double-click the VI you want to use as a subVI, and place it on the block diagram. Textual programming environments are typically used in determining high throughput virtual instrumentation systems, such as manufacturing test systems. The increased demand for information at all levels of the enterprise and in consumer products requires you to network embedded systems while continuing to guarantee reliable and often real-time operation.

A write local or global has a thin border similar to an indicator.

In addition, these measurements can be complex—requiring frequency, amplitude and temperature sweeps with data collected and analyzed throughout. If you have multiple operations that use previous iteration values within a loop, use multiple shift registers to store the data values from isntrumentation different processes in the structure as shown in Figure 4.


For example, if a switch has a green border, you can wire a switch to any input with a green label on an Express VI. A flexible commercial-off-the-shelf COTS hardware prototyping platform which supports the software platform and offers customizable components minimizes the time to first prototype because the time and money required for designing custom hardware is eliminated. This book is designed for undergraduate and postgraduate students of instrumentation and control engineering, electronics and instrumentation engineering, electrical and electronics engineering, electronics and communication engineering, and computer science and engineering.

Stacked shift registers, as shown in Figure 4. Create a VI that takes a number representing Celsius and converts it to a number representing Fahrenheit.


With virtual instruments, we can quickly develop a program, take measurements from an instrument to test a prototype and analyze results—all in a fraction of the time required to build tests with traditional instruments. Builds the concept of virtual instrumentation by using clear-cut programming elements.

Find both the values of the roots and the nature of the roots.

Click the button again to disable continuous running. When you click the Step Into button again, it executes the first action and pauses at the next action of the subVI or structure. Up to Owning palette—Navigates up one level in the palette hierarchy.

Offers a number of solved problems to help students gain hands-on experience of problem solving. Warning and Disclaimer While every precaution has been taken in the preparation of this book, the author and the publisher do not guarantee the accuracy, adequacy, or completeness of any information contained in this book. Required is not available for terminal outputs. Check whether the given number is in the limit specify upper and lower limits.

Place controls and indicators on this front panel the same way you do on a standard front panel. To display a terminal as a data type on the block diagram, right-click the terminal and select View As Icon from the shortcut menu.

Keys to its success include rapid PC advancement; explosive low-cost, high-performance data converter semiconductor development; and system design software emergence. Builds the concept of virtual instrumentation by using clear-cut programming elements.
