Using VI Server to Control LabVIEW
VI Server is one of LabVIEW’s powerful features. In this video, we break down what VI Server actually is, how it works, and when you should use it in your LabVIEW applications.
You’ll learn how VI Server enables programmatic control of VIs, front panels, block diagrams, and application instances using references and property/invoke nodes. We’ll cover common use cases like dynamic loading, scripting-style automation, and advanced debugging techniques, as well as the performance, maintainability, and security implications that come with it.
This video also discusses why VI Server can be risky in production systems, how it impacts application architecture, and best practices for keeping your code robust and secure—especially in regulated or locked-down environments.
Topics covered:
-What VI Server is and how it works
-VI references, property nodes, and invoke nodes
-Common use cases and anti-patterns
-Performance and security considerations
-Best practices for production code
Whether you’re just encountering VI Server for the first time or you’ve inherited a project that relies heavily on it, this video will help you understand how to use it responsibly and effectively.
