Virtual Instrumentation Case Study

Application

Boeing used LabVIEW and 70 PXI chassis to collect over 300 channels of acoustic data simultaneously in their research to decrease noise during takeoff

NI Products

LabVIEW, PXI

"Using NI software and hardware, we were able to

create a high-end, low-cost system that could distribute the acquisition system across multiple chassis, tightly

synchronize all channels, provide high channel count with full bandwidth on all channels simultaneously, and

allow virtually unlimited channel-count expansion. “ -- James Underbrink, Boeing Aero/Noise/Propulsion Laboratory

Control for Steel Rolling Mill

Images: Integrated Industrial Systems (I2S)

With NI LabVIEW graphical programming tools, we quickly programmed the FPGA and real-time processor in CompactRIO. Because CompactRIO and our PLCs are Ethernet based, we successfully integrated the CompactRIO PAC with our control systems to optimize our rolling mills with minimal changes to our existing control architecture.
