The pressure of achieving short time to market and the reality of cost cutting mean that todays engineer is frequently focused on improving the productivity of the product-development process. You need to carefully choose tools that provide the best results and discard or replace those that dont meet your needs. You must evaluate criteria such as performance, cost, functionality, and quality, while ensuring that these tools can work within your current environment, increase productivity, and maintain scalability. At National Instruments we build products with these criteria in mind better productivity, lower cost, integration, performance, and reduced development time.

National Instruments LabVIEW encompasses these criteria through its powerful graphical development environment. Since 1986, engineers and scientists have relied on LabVIEW for their testing, measurement, data acquisition, and control needs. Whether in research, design, validation, production test, or bVIEW also provides native drivers for more than 4,000 different instrument models.

LabVIEW also maintains a full range of options for communications and data standards, such as TCP/IP, OPC, SQL database connectivity, and XML data formats.

The success of customers best illustrates the long-term value and flexibility of LabVIEW. An engineer at ORTHSTAR, a systems integrator for factory automation, process control, and other industries since 1974, made the following comments: [We] like using LabVIEW because we can develop a customized system to meet each customers unique requirements. Also, the flexibility of LabVIEW ensures that we can scale the system to increase its capabilities as the customer needs increase or as changes need to be applied. ORTHSTAR delivered a production-line system for Toshiba Display Devices where Toshiba specified LabVIEW, no downtime after installation, continuous operation 24 hours a day, and flawless execution the first time out. This system had to interface with hundreds of individual pieces of manufacturing and test equipment to provide just-in-time delivery from the line. ORTHSTAR estimates that had they written this application using C/C++, the length of development time would have been too great to meet Toshibas target date. However, they completed the project within 16 weeks using LabVIEW and were so successful that as of the beginning of 2001, they now control 10 of 15 lines in the same facility using LabVIEW.

Industry-Standard Software

As mentioned previously, you lower your risk when you use software that is considered an industry standard. In the case of LabVIEW, many companies have successfully used it for a large number of applications. The preference of engineers across the globe speaks for itself. In 2003, National Instruments sold products to more than 25,000 different companies in more than 90 countries around the world.

Market resea rch shows the widespread adoption of LabVIEW for data acquisition and control applications. The following findings illustrate that many engineers and scientists prefer LabVIEW and National Instruments products over other options for their PC-based data acquisition and test instrumentation needs.

"LabVIEW is a programming language, equivalent to C++, Visual Basic, or any other language. It is the ONLY widely accepted graphical programming language. Graphical programming is a language of the future and carries with it many important programming concepts. I feel, it is the responsibility of universities (such as Penn State) to expose, at least, every computer science and engineering student to these new concepts."

Quality and Integration.

As you create your applications to cover all phases of product development, from design to research, development, manufacturing, and finally production, you realize that quality and integration play a very important role. National Instruments software engineers, digital and analog hardware engineers, chip designers, measurement and signal processing experts, and many more engineers work closely with one another to ensure that the multitude of products integrate well together and provide a high level of quality.

Using a standard measurement services architecture, LabVIEW integrates tightly with a complete array of National Instruments hardware. This layer of services includes data acquisition, instrument control, motion control, vision, GPIB, FieldPoint distributed I/O, PXI systems, reconfigurable I/O, and VXI systems. With this architecture, you can abstract the particulars of the diverse instrumentation and I/O and present a uniform interface to help you quickly build your custom application. National Instruments completes the platform with the powerful TestStand test management software, as well as LabWindows/CVI for C and Measurement Studio tools for Microsoft Visual Basic and Visual Studio .NET. With all this in mind, you see how easily you can integrate LabVIEW with existing systems, eliminating the need to modify your equipment, while extending its usefulness with state-of-the-art software tools.

Motorola took advantage of this integration when developing a Cellular Base Solution. Here, the challenge was to [develop] a single test software application capable of testing a wide variety of Motorola cellular base station products. The goal of this project was to maximize reuse while minimizing duplicated effort and dramatically reduce future time to test. They decided to use LabVIEW as the development environment, because [the] LabVIEW graphical programming language is pe rfect for test automation. It is simple to code and offers numerous functions for maximum productivity. In this solution they mention that creating a common test application resulted in a large cost reduction and that [their] combined annual maintenance costs were reduced from $700,000 to $400,000. [Their] annual projected new product test development costs fell from roughly $200,000 to $25,000. (NI Customer Solution, Using TestStand for Testing Cellular Base Solution)

Significant Productivity Gain

Your choice of software is important because software is generally the central component that ties your entire system together. Choosing the right software can maximize productivity, while a software package that doesnt fit your needs could drain time and productivity. LabVIEW can help you get more projects done in less time by streamlining the process from inception through completion. There are several characteristics of LabVIEW that contribute to a significant gain in productivity when compared to other development software:

1. Easy to Learn
The one factor that greatly contributes t o starting your application faster is the initial learning curve generally associated with any software tool. A tool can be used to its full potential only when you become proficient and understand the intricacies associated with it. LabVIEW significantly reduces the learning curve by providing an intuitive interface and a set of tools that encapsulate functionality, while abstracting the underlying enabling technology. By browsing through the examples included, online help, and the LabVIEW Getting Started Guide , you take measurements from plug-in measurement devices and stand-alone instruments in the very first hour of usage. Just as quickly, you are able to graph, analyze, and save data. These exercises, designed to quickly teach you the principles of graphical programming, help you become familiar with powerful LabVIEW development and debugging tools.

Once you feel comfortable with the introductory material, you are ready to start your project. While you develop your application, you have numerous resources available such as online help, printed manuals, Web-based help, and tutorials. LabVIEW even incorporates tools for automatic code generation for common application tasks. This gets you up and running quickly, while allowing you to modify this generated code as you become more familiar with the environment. One feature that enhances your initial experience with LabVIEW is the fact that the development environment relies almost exclusively on a drag-and-drop interface, which is second nature to users of computer technology.

2. Easy to Use
Beginning with the release of LabVIEW in 1986, National Instruments has focused on providing an easy-to-use tool that enhances productivity for engineers and scientists just as the spreadsheet empowered the financial community. In every release, LabVIEW continuously improves based on usability research, customer feedback , and better technology. LabVIEW simplifies even the most challenging tasks, such as multithreaded parallel execution, through the dataflow technology. Additionally, express technology, introduced with LabVIEW 7 Express, provides a simplified, configuration-based approach to LabVIEW development that makes programming easier than ever.

3. Complete Functionality
Ease of use is not the only factor that provides the best productivity. You want to be sure that the products and tools satisfy all your requirements and those of the project. You often have to make decisions on products that result in trade-offs, where ease of use and functionality are the most commonly opposed characteristics. LabVIEW satisfies both. With LabVIEW, you will easily scale to meet current and future requirements, whether you need to create a small, easy-to-use instrument control application or a solution that monitors and controls your entire factory. You can select from different development packages with varying degrees of functionality. Even if you initially select a basic LabVIEW package, you can easily upgrade to the more complete versions to increase power and flexibility. You can build a complete solution with LabVIEW, because it offers all the necessary tools and features for any measurement and automation application:

Powerful Built-In Functionality LabVIEW development systems include a complete set of tools geared specifically for data acquisition, instrument control, and other measurement tasks. Other tools include measurement analysis (more than 450 analysis functions), simulation, Web and network connectivity, visualization, storage, and report generation.
Add-On Software for Special Needs Powerful LabVIEW toolkits have been developed by National Instruments and other companies. These add-ons expand and enhance the core functionality of LabVIEW for specialized ta sks. Many companies continuously develop and sell tools that work with or use LabVIEW for industry-specific needs such as biomedical applications, telecommunications, automotive, and others.
Configuration-Based Tools National Instruments offers tools that help you satisfy specific needs in a nonprogrammatic configuration-based environment. For example, with DAQ Assistant, you simply configure your data acquisition system using an interactive window and LabVIEW generates all of the necessary code for you. Similarly, using Instrument I/O Assistant, you can configure your instrument control application while LabVIEW generates the underlying code, saving up to 80 percent of your development time.

4. Modular Development
When you have a large project, you break it down into functional solvable units. You can more easily manage and test these subtasks because you reduce dependencies that might cause unexpected behavior. Once you complete these subtasks, you can put them together to build the system. The ease with which you accomplish this division of tasks depends greatly on the underlying architecture of your software.

Breaking down a problem into smaller pieces is a main principle of LabVIEW. Full-featured modules, or subroutines, make up the code in LabVIEW, and you can individually execute, edit, and test each of them. Developing your applications in this paradigm offers several advantages:

  • Reusability of code modules saves time and effort
  • High-level diagram offers more clarity of system functionality than lines of code
  • Modularity of code offers easier debugging, testing, and integration with high-level systems

Your main concern is to reduce the time it takes to reach a solution. LabVIEW gives you the necessary tools to increase productivity, from rapid prototyping to design and delivery, because it was built with the goal of helping you rapidly create measurement and automation solutions.

Solid Performance

When prioritizing the requirements for your project, you may consider performance the most important. To guarantee solid performance, a company may accept inferior software in terms of ease of use, cost, or openness. However, this perception of performance may not equal reality, and the trade-off could prove unwise for the organization.

LabVIEW has been developed to provide exceptional performance in many types of applications. For instance, unlike some other software languages, LabVIEW does not generate intermediate code or any type of script, which means LabVIEW code executes quickly. Additionally, LabVIEW automatically takes advantage of multithreaded OSs to deliver parallel execution between multiple execution processes and between the code and user interface. All of the multithreading is handled by LabVIEW so that the developer can focus on the real purpose of the application.

Because LabVIEW offers these performance benefits, you can deploy LabVIEW anywhere, even in such demanding applications as manufacturing test and control, as well as enterprise-wide network solutions. For example, at Knowles Electronics, implementing a LabVIEW-based test system resulted in a 5-to-1 reduction in test time at their high-volume manufacturing facility for microphones and receivers. (NI Customer Solution, Knowles Increases Production with NI PC-based DSA) Lexmark, using a National Instruments high-speed digitizer device and LabVIEW, increased the quality of their products and production yields, and maintained test performance with minimal development expenses. (NI Customer Solution, Lexmark-When Speed and Accuracy Matter)

With LabVIEW, you can generally distribute your applications as stand-alone executables free of charge and even build your own installers. This feature is important for solutions that need to be deployed to a large number of systems.

Considerations When Selecting Software Tools

You are ultimately responsible for making the right choice that will satisfy your organizations needs in the short term as well as the long term. Long term vision is important not only for cost purposes, but also for scalability and adaptation to future projects. There are several factors to consider when evaluating for long-term viability:
1. Can the software scale to different platforms?

The majority of computer systems use some variation of the Microsoft Windows OS. Nevertheless, there are other options that offer clear advantages for certain types of applications. Real-time and embedded development continues to grow rapidly in most industries as computing power is packaged into smaller and more specialized packages. Minimizing your losses resulting from a transition to new platforms and choosing the right software for this purpose are key factors.

LabVIEW minimizes this concern, because it runs on Windows XP, 2000, and NT, as well as Mac OS X, Sun Solaris, and Linux. LabVIEW can also compile code to run on ETS and Windows RTX real-time OSs through the LabVIEW Real-Time Module to deliver deterministic, reliable performance. You can also port LabVIEW code onto handheld PDAs with the LabVIEW PDA Module and configure custom hardware using the LabVIEW FPGA Module. Additionally, LabVIEW is platform independent; programs that you write for one platform transparently port to any other LabVIEW platform simply by opening the VI.

2. Can people with varying degrees of software expertise use it?

The software you select should be versatile enough that different types of users, with varying levels of knowledge, can use it. With LabVIEW, users at many different levels of programming experience can develop sophisticated applications. Users range from NASA rocket scientists to university undergrads to kindergartners programming LEGO-based robots with LabVIEW-based ROBOLAB. Software expertise in other languages or previous experience is a minor factor when working with LabVIEW. People with little or no programming experience, as well as experts in object-oriented programming, find that LabVIEW covers their design and productivity needs. A useful comparison is Microsoft Excel, where both beginner and experienced users find the tool very useful and scalable. In a similar fashion, users uncover increasing functionality as their proficiency in LabVIEW increases. As mentioned above, LabVIEW is easy to learn, but as you become more proficient, the problems you can solve grow along with your experience.

3. Does it adapt to new technology?

To ensure the best investment of your resources, you try to minimize your companys experimentation with new technologies, doing so only when absolutely necessary. However, when you discover breakthroughs and significant innovations that significantly improve performance, lower costs, and offer your company a competitive advantage, you need to adapt. Software that is ahead of the technology curve integrates these technological innovations with minimal time and effort. This is the best way to incorporate new technology into your products and processes.

LabVIEW consistently embraces new computing platforms, communication buses, technologies such as multithreading and ActiveX, the Internet, PDAs, networking, XML, wireless, distributed applications, and most recently reconfigurable I/O hardware. LabVIEW selectively incorporates such technologies and makes it simple for you to take advantage of them, effective ly minimizing your learning curve and helping you keep pace with rapid technology changes. This ensures that you maintain a stable platform over time, yet still have access to new, cutting-edge technologies.

4. Is it open to other software and hardware? Does it conform to open standards?Standardization of software relies greatly on the ability of the package to work well with other software, measurement and control hardware, and open standards that define interoperability between multiple vendors. By selecting software that meets these criteria, you ensure that your company and applications can incorporate a wide variety of hardware and software tools to meet your cost and performance needs, thereby maximizing your investments over the long term.

A large number of third-party hardware and software vendors develop and maintain hundreds of LabVIEW libraries and instrument drivers to help you easily make use of their products with LabVIEW. However, this is not the only way to provide connectivity to your LabVIEW-based applications. LabVIEW offers simple ways to incorporate ActiveX software, dynamic-link libraries (DLLs), and shared libraries from other tools. In addition, your LabVIEW code itself can be shared as a DLL, shared library, or via ActiveX.

With LabVIEW, you can easily integrate hardware, such as stand-alone instruments, data acquisition devices, motion control and vision products, PLCs, TEDS, and countless protocols such as GPIB/IEEE 488, serial/RS232, USB, Bluetooth, IEEE 1394, and 802.11 to build a complete measurement and automation system. LabVIEW also incorporates major instrumentation standards such as VISA, an interoperable standard for GPIB, serial, and VXI instrumentation; PXI and software and hardware based on the PXI Specification managed by the PXI Systems Alliance; IVI interchangeable virtual instrument drivers; and VXI plug&play, a driver standard for VXI instruments.
