LabWiew 7.1 is billed as a significant upgrade to the family of LabView graphical development products. The new release extends Express technology to automated instrumentation and real-time applications with new Express VIs for modular instruments and NI-DAQmx, advanced debugging, and low-level execution timing for a real-time module.

There are five new Express VIs for digitizers, signal generators, and high-speed digital I/O. Engineers can configure sophisticated measurements and acquire data with few mouse clicks.

The redesigned NI-DAQmx measurement services software in LabView 7.1, available in real-time applications, increases performance of single-loop PID applications by 30 percent and simplifies hardware-times loop implementation. In addition, the new PDA module delivers more data acquisition functionality, including faster multichannel acquisition and analog and digital triggering. Engineers can use this module to create handheld DMM applications and communicate with Bluetooth-enabled devices.

LabView 7.1 also includes advanced execution timing and graphical debugging for low-level control and visibility of real-time system execution. With the new timed lop, an enhanced loop in LabView, engineers can specify precise timing of code segments, coordinate multiple time-critical activities, and define priority-based loops for creating multi-rate applications.
