OPC to Web - Java Demo #2
If you're not able to see the live demo
The image below represents what you would have seen if your firewall were not blocking access to our web server on port 4600. Each of the live elements in the display is a separate Java applet. All of the applets on the page share a common link back to a DataHub running on one of our web servers. The display elements update, in real-time, without the user having to press the Refresh button on the browser.
The user can also enter data through this interface to change the SP value and cause changes to the data being generated on the server. Anyone who is also watching this web page would see you changing the SP value and see exactly what you are seeing in your browser window.
