How to see your data in the Table View 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 display your data in the Table View page, just follow these simple steps:
- Make sure the computer running the OPC DataHub is accessible on the network.
- 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.
- Open a web browser on the client computers and type the following URL into the address bar:
- http://{computer address}/table.asp?parent={domain name}:{branch}.{sub-branch}
- Where {computer address} = the IP address or network name of the computer running the OPC DataHub.
- and {domain name} = the name of the DataHub domain (or branch) that contains the data you want to display. Sometimes, the organization of the data within the DataHub can be quite complex, including branches and sub-branches. This is often the case when reading data from an OPC server that has a multi-level data hierarchy. In these cases we reference locations within the data structure using the syntax shown above.
- For example,
- http://localhost/table.asp?parent=DataPid:PID1
- http://192.168.5.55/table.asp?parent=Plant_1
Display data from the Plant_1 domain within the DataHub.
- http://PlantServer/table.asp?parent=Section_1:Zone_1
Display data from the Zone_1 branch within the Section_1 data domain.
- http://PlantServer/table.asp?parent=Section_1:Zone_2.Temp.Setpoints
Display data from the Setpoints branch, three levels down the tree structure within the Section_1 data domain.
- http://localhost/table.asp?parent=Area2
You can just type localhost/... if you are running the web browser on the DataHub computer.
