LabVIEW: Visual Programming Platform for Engineers & Scientists

LabVIEW is a visual programming platform used by engineers and scientists to develop complex measurement, test, and control systems. It uses a graphical interface to visualize code, similar to building a flowchart.

What is LabVIEW?

LabVIEW (Laboratory Virtual Instrument Engineering Workbench) is a system design platform and development environment for visual programming language from National Instruments. It is commonly used by scientists and engineers to develop sophisticated measurement, test, and control systems.

LabVIEW differs from traditional programming languages in that it uses a graphical interface to visualize code, similar to building a flowchart. The flowchart-style programming makes it intuitive to learn and allows complex logic to be developed quickly. Engineers and scientists often choose LabVIEW because it integrates well with hardware from National Instruments for applications like data acquisition, instrument control, and machine vision.

Some key capabilities and features of LabVIEW include:

  • Graphical programming - Uses a block diagram interface to visualize code and data flow
  • Hardware integration - Seamlessly interfaces with National Instruments data acquisition devices, GPIB instruments, cameras, and more
  • Analysis tools - Advanced signal processing, mathematics, statistics, and machine learning toolsets for analyzing measurements
  • Reporting - Custom reporting features to easily share and document results
  • IP and code reuse - Ability to integrate and reuse code using IP libraries, DLLs, .NET assemblies
  • Cross-platform compatibility - LabVIEW code can run on Windows, Linux, macOS, and more

LabVIEW is commonly used in industries like manufacturing, automotive, aerospace, defense, academics, electronics, and more. Example applications include test automation, production test systems, hardware-in-the-loop simulation, machine vision, and process control.
