![]() VI refers to virtual instrument and is a program module of LabVIEW. The data flow between the nodes in the block diagram determines the execution order of VIs and functions. ![]() The traditional text programming language determines the program execution order based on the order of statements and instructions, while LabVIEW uses data flow programming. LabVIEW (Laboratory Virtual Instrument Engineering Workbench) is a graphical programming language for creating applications with icons instead of text lines. LabVIEW also has traditional program debugging tools, such as setting breakpoints, displaying the results of data and its subroutines (subVIs) in an animated manner, single-step execution, etc., to facilitate program debugging. The function library of LabVIEW includes data acquisition, GPIB, serial port control, data analysis, dataĭisplay and data storage, etc. Like C and BASIC, LabVIEW is also a general-purpose programming system with a huge library of functions to complete any programming task. The LabVIEW development environment integrates all the tools engineers and scientists need to quickly build a variety of applications, and is designed to help engineers and scientists solve problems, increase productivity, and continuously innovate LabVIEW software is the core of the NI design platform and is also ideal for developing measurement or control systems.
