4.3. Creating New Points

OPC DataHub™ : Version 6.4
	Chapter 4. OPC Bridging

A special feature of the OPC DataHub allows you to create new points. Combined with the ability to create new data domains, this lets you create:

Personalized data sets for different users or groups.

Aggregated data sets that combine selected data points from different servers and serve it up from a single OPC server (i.e. the DataHub).

Scaled data sets that apply one or more transformations to a subset of the data.

Temporary data sets for testing and demonstration purposes.

Any combination of the above.

You can create a new point in the Source or Destination panel of the Bridging Configuration window by typing in a new point name in the entry field.

And with a few mouse clicks you can quickly create bridges to new destination points.

Just click on a source point, click on a data domain, and then click Apply. A destination point with the same name as the source point gets created automatically in the data domain you chose, with the current transformation applied.

You might want to create special data domains for holding sets of destination points. For more information about data domains, please refer to Section 17.4.1, “Data Domains”.
