Streaming AJAX - DataHub Browser View

This example shows the DataHub Browser, a Streaming AJAX application that lets you display live data without having to do any web programming. To see the data, expand the DataPid tree, then click the PID1(4) domain. The numbers in ( ) represent the number of data points in that particular DataHub domain.
How to see your data in the DataHub Browser page
If you install the DataHub on a computer connected to a network or the Internet, then anyone with a web browser can see the live data from your system.

To access the DataHub Browser page directly, you simply do the following:
  1. Make sure the computer running the OPC DataHub is accessible on the network.
  2. Run the OPC DataHub and connect to your OPC servers or other sources of data.
    See our DataHub videos for more details on how to connect to do this.
  3. Open a web browser on the client computers and type the following URL into the address bar:
    • http://{computer address}/datahub.asp
    • Where {computer address} = the IP address or network name of the computer running the OPC DataHub.
    • For example,
      • http://localhost/datahub.asp
        You can just type localhost/... if you are running the web browser on the DataHub computer.
      • http://192.168.5.55/datahub.asp
      • http://PlantServer/datahub.asp
