  1. Extending LabVIEW to the Web Using the LabSocket System John Bergmans Bergmans Mechatronics LLC National Instruments LabVIEW User Group Meeting Huntsville, AL Nov 13, 2013 1616 Bedford Lane, Unit A phone: 714-474-8956 Newport Beach, CA 92660 web: bergmans.com

  2. Bergmans Mechatronics LLC Current Approaches to Remote LabVIEW Access • Native Client App • Use TCP/IP sockets, LabVIEW shared variables, or .NET, to transmit data between client and LabVIEW • Requires custom client development and modifications to LabVIEW app • LabVIEW Remote Panels • Requires LabVIEW Run-Time Engine (RTE) and browser plug-in on client platform • LabVIEW Web Services • Data transferred between application and client using the HTTP request-response model (REpresentative State Transfer (REST) architecture) • Requires development of client software using Web languageseg. HTML/JavaScript • LabVIEW Web UI Builder (http://www.ni.com/uibuilder/) • Build and run apps in browser using reduced-capabiliy LabVIEW • Requires Silverlight plug-in (runs on Windows and Mac OS X) • Data Dashboard for LabVIEW • Requires development of user interface and linking UI to block diagram • Limited to iOS, Android, Windows 8 and Windows Phone devices

  3. Bergmans Mechatronics LLC LabSocket System WebSocket Interface (Over TCP-IP) HTTP Server “Target VI” Browser TCP-IP Socket Interface Message Broker LabSocket Support VIs Browser LabVIEW Host Platform LabSocket Server Platform Browser • LabSocket Support VIs • Startup • - LabVIEW Front Panel screenscrape, send HTML and JavaScript code to HTTP server • Continous Operation • - Transmit updates of LabVIEW front panel to browser • - Update LabVIEW front panel when user generates events in browser HTML5 WebSockets enable automatic replication of LabVIEW front panel in a browser without plug-ins
