Introduction to the LabVIEW EnvironmentFront Panel

Block Diagram

NI LabVIEW Environment—Dataflow• Each node (subVI or function) executes once all its inputs

become available • Parallel execution inherent in graphical nature• Multithreaded execution for improved performance and system

resource management

Modularity• Modular design• Hierarchal system with subVIs• Reusable building blocks similar

to subroutines

“The robustness of LabVIEW, combined with its graphical programming environment, ensure that we can quickly complete the application and adapt it to unique customer requirements.”—Dirk De Mol, Manager, Honeywell-Measurex describing a LabVIEW measurement and control system for sheet process products with more than 3,000 VIs
