NI-DAQmx 7.2 is the latest version of the measurement services software from National Instruments that offers advanced functionality compared with using basic data acquisition drivers.
NI-DAQmx 7.2 is the latest version of the measurement services software from National Instruments that offers advanced functionality compared with using 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 new 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 1Msample/s waveform output, up to 80MHz counter/timer operations, up to 10Msample/s simultaneous sampling analogue input and 24bit resolution dynamic signal acquisition with 100dB of dynamic range.
NI-DAQmx technology also extends the revolutionary performance enhancements of optimised 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 implementation of timed loops and delivers real-time feedback for these applications.
These new features are ideal for integrating PXI-based data acquisition devices into control systems that run a PID loop at a rate greater than 50kHz, an increase of more than 30% compared with previous versions of NI-DAQ.
