The following example shows a potential industrial device being controlled in real-time from a Macromedia Flash application running within a browser window. The Flash application, which is designed with the Macromedia Flash toolsets, can communicate in real time with the server and the server can also update dials and gauges asynchronously without the need of refreshing the screen. The persistent bi-directional communication layer makes it possible for JavaScript code in the server to call Flash ActionScript (JavaScript) asynchronously at any time.
You can download the Barracuda demo for Windows NT if you would like to see working examples of a browser based GUI being updated in real time from the server.
