Extending LabVIEW to the Web Using the LabSocket System

Presentation Summary

The LabSocket system enables remote access to LabVIEW application using desktop or mobile web browsers without the need for browser plugins or a client-side run time engine.  The system supports commonly used front panel elements, including Waveform Charts and Graphs, XY Graphs, MultiColumn ListBoxes and Tabs.  The LabSocket-RT version of the system, with support for a limited set of front panel elements, enables browser access to LabVIEW Real-Time applications operating on platforms such at the CompactRIO.

A key technology used in the system is the HTML5 WebSocket interface which enables continuous, bi-directional communication with a web browser.  This technology also contributes to the name of the system: "LabSocket = LabVIEW + WebSocket".

This presentation provides an overview of the system theory of operation, several existing applications for the system, and live demonstrations.  Additional information about LabSocket is available at http://labsocket.com.
