A third common application for DataHub bridging is creating custom data sets. You can select certain data points from several OPC servers and group them into different data domains depending on the user. This has two advantages:

For example, suppose you needed to get OPC data to three sets of users: accounting department staff, executives on the road, and an OPC server at a remote plant. You could declare three new data domains, such as Accounting, Executive, and Remote. For each data domain, you would then create new points specific to the needs of those users. With this approach, you can limit the data set and customize it for each recipient.
