Learn LABVIEW-G-SCRIPTING with Real Code Examples

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.

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

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

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

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

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

Architect: develop large-scale automated VI generation systems

G Scripting vs Manual VI Editing: faster and scalable

G Scripting vs LabVIEW VI Server: programmatic vs runtime control

G Scripting vs Python/Matlab: native LabVIEW integration

G Scripting vs TestStand: VI-focused automation vs test sequence automation

G Scripting vs LabVIEW Macros: more flexible and customizable
