Express technology extended for automated instrumentation and real-time systems

LabVIEW 7.1 is an upgrade to the family of LabVIEW graphical development products. It extends Express technology to automated instrumentation and real-time applications with Express VIs for NI modular instruments and NI-DAQmx, advanced debugging and low-level execution timing for the LabVIEW 7.1 Real-Time Module. The improvements enable engineers to configure sophisticated measure-ments and acquire data easily.
The redesigned NI-DAQmx measurement services software in LabVIEW 7.1, available in real-time applications for the first time, increases performance of single-loop PID applications by 30% and simplifies hardware-timed loop implementation. In addition, LabVIEW 7.1 PDA Module delivers more data acquisition functionalities, including faster multichannel acquisition as well as analog and digital triggering.

With the new timed loop, engineers can specify precise timing of code segments, coordinate multiple time-critical activities and define priority-based loops for creating multirate applications. To further optimize performance of their applications, engineers can use the new LabVIEW Execution Trace Toolkit with the LabVIEW Real-Time Module to quickly identify sources of jitter, such as memory allocation and race conditions.
