NI Offers Real-Time Capabilities with NI-DAQmx Measurement Software

4/21/2004 - National Instruments announced NI-DAQmx 7.2, the newest version of its measurement services software that offers advanced functionality improvements compared to basic data acquisition drivers. Engineers can use NI-DAQmx to save substantial configuration time while improving system performance through new capabilities such as plug-and-play TEDS “smart” sensing technology and LabVIEW Real-Time control.

The new plug-and-play transducer electronic data sheets (TEDS) offered in NI-DAQmx 7.2 integrate smart sensor technology into measurement systems as easily and quickly as connecting a mouse to a computer. This functionality not only simplifies sensor configuration for existing and new NI data acquisition hardware but eliminates manual data entry and delivers automated system detection and configuration. NI-DAQmx 7.2 also streamlines system configuration by offering dynamic display of terminal connections, showing engineers exactly where they should wire each configured sensor.

The step-by-step DAQ Assistant included in NI-DAQmx 7.2 saves development time by automatically generating code for various measurement types, such as sound pressure, and more than 20 additional NI measurement products. Engineers can use NI-DAQmx to build test and control systems with up to 1 MS/s waveform output, up to 80 MHz counter/timer operations, up to 5 MS/s simultaneous sampling analog input and 24-bit resolution dynamic signal acquisition with 100 dB of dynamic range.

NI-DAQmx technology also extends the revolutionary performance enhancements of optimized single-point loops and multithreaded, concurrent I/O to real-time control applications in the LabVIEW environment. Available for real-time applications for the first time, NI-DAQmx simplifies implantation of timed loops and delivers real-time feedback for these applications. These new features are ideal for integrating PXI-based data acquisition devices in control systems that run a PID loop at a rate greater than 50 Khz, a more than 30 percent increase compared to previous versions of NI-DAQ.

National Instruments Data Acquisition
By integrating commercial PC-based technologies and investing in innovative research and development, NI continues to lower the cost of measurement and control while improving system performance, accuracy and reliability. NI recently increased value for its data acquisition (DAQ) customers by reducing prices up to 25 percent worldwide for 13 of its most popular DAQ modules.
