At its annual user conference (NIWeek), National Instruments released LabVIEW 8.6 and announced 10 new WiFi and Ethernet data acquisition (DAQ) devices, extending NI measurement hardware and software to wireless remote monitoring applications.

The company also showcased a partner-designed system being used by Chinese engineers to conduct structural health research on seven megastructures, including main venues for the 2008 Summer Olympics.

The WiFi and Ethernet devices include built-in signal conditioning and direct sensor connectivity for electrical, physical, mechanical, and acoustic signals. Engineers and scientists can combine NI WiFi DAQ with the NI LabVIEW software platform to meet wireless structural diagnostic, environmental, and machine condition monitoring application needs.

Using IEEE 802.11 standard for wireless networks, NI WiFi DAQ devices stream data on each channel at more than 50 kS/s with 24 bits of resolution and deliver measurement data to a host PC instantaneously for real-time viewing and in-line analysis of dynamic sensor signals.

The WiFi DAQ built-in network authentication methods and 128-bit AES encryption are said to offer high network security and meet National Institute of Standards and Technology (NIST) wireless network standards.

LabVIEW 8.6 is the latest version of NI’s graphical system design software platform for control, test, and embedded system development. Now, advanced control systems can be designed using programmable automation controllers (PACs) based on field-programmable gate arrays (FPGAs).

According to NI, LabVIEW 8.6 simplifies the programming of NI CompactRIO control and acquisition hardware via a new scan engine to integrate timing into the programming language. The new scanning I/O architecture is said to provide out-of-the-box I/O determinism of better than 500 ns.
