Explain
LabVIEW G Scripting provides programmatic control over LabVIEW VIs and block diagrams.
It allows automating repetitive design tasks, generating code, and creating dynamic VIs.
Used in test automation, measurement, control systems, and embedded applications.
Supports both graphical and textual programming concepts for complex logic.
Widely adopted in engineering, research, and industrial process automation.
Core Features
Access VI properties, terminals, controls, and indicators
Create, delete, or modify nodes and wires programmatically
Traverse block diagrams to inspect or modify structure
Automate repetitive coding and testing tasks
Generate documentation or reports of VI logic
Basic Concepts Overview
VI - Virtual Instrument, the basic LabVIEW program unit
Block Diagram - graphical code representation inside a VI
Control/Indicator - inputs and outputs of a VI
Node - functional element inside a block diagram
Wire - connection between nodes transferring data
Project Structure
LabVIEW project (.lvproj) containing multiple VIs
VI files (.vi) with block diagrams and front panels
Scripting VIs or scripts (.vi) for automation tasks
Data files for input/output
Documentation or configuration templates
Building Workflow
Identify repetitive tasks or VIs to automate
Access VI and block diagram programmatically using scripting
Modify or generate nodes, wires, controls, or indicators
Test scripts on sample VIs to validate behavior
Deploy automated VI creation or modification across projects
Difficulty Use Cases
Beginner: read and modify simple VI properties
Intermediate: automate simple block diagram changes
Advanced: create new VIs with multiple nodes and controls
Expert: integrate scripting with test automation hardware
