New LabVIEW version instantly enables web-based measurements

13 February 2002 Test & Measurement

National Instruments' LabVIEW 6.1 graphical development environment for test, monitoring, and control applications, builds on the web capabilities of LabVIEW 6i by simplifying the creation of remote applications and integrating the latest technologies for XML and wireless communications.

This software makes it easier for engineers to control their applications from any commonly used web browser - anywhere in the world. In two mouse clicks, engineers can instantly embed their application's front panel in a web browser, reducing the time and costs typically associated with developing remote applications. This feature makes it possible for colleagues across the office or across the globe to connect to the same system and view an application in realtime. Engineers can also control hardware from a separate office or from home, increasing efficiency and reducing development costs.

In addition to the new tools that maximises the advantages of the web, LabVIEW 6.1 uses the latest commercial technologies to expand networking capabilities. The newest version works seamlessly with Windows XP that has increased networking features and enhanced stability. LabVIEW 6.1 also introduces wireless infrared data communications protocols, empowering engineers to create applications that communicate with wireless devices, such as PDAs. Import and export of XML-formatted data is also possible to integrate VIs with other web or database applications in the enterprise.

LabVIEW 6.1 expands on the measurement capabilities of LabVIEW 6i in terms of an increase the accuracy, efficiency, and speed of measurement and analysis. The point-by-point analysis libraries increase application performance and enhance realtime response acquisition and processing data a single point at a time at relatively high speeds, such as in closed-loop control applications. It also includes functions that increase fast Fourier transform (FFT) analysis speed by as much as 10 times over LabVIEW 6i. Event-driven programming also simplifies the development of sophisticated user interfaces.

NI is releasing the latest versions of the realtime module and the datalogging and supervisory control module. With this tightly integrated family of LabVIEW products, engineers can easily build targeted applications for measurement, monitoring, and control. The LabVIEW realtime module extends LabVIEW graphical development to enable creation of deterministic, realtime applications. The datalogging and supervisory control module is an ideal tool for distributed monitoring applications and now offers enhanced historical data management tools in addition to built-in features for monitoring applications.
