Load these additional configuration files when starting:

Configuration files let you start the OPC DataHub from a known configuration. Normally there is one configuration file that comes with the DataHub distribution. Each change you make in the Properties window gets written to that file automatically, and saved. However, it is also possible to create and/or edit configuration files with a text editor (see AppendixB, Configuration Files).

Any additional configuration files must be listed here in order to be read by the OPC DataHub. The files in the list are used in order from the top down, with the last file taking precedence. That is, if a value is assigned to a variable from within a configuration file, its value will be changed by subsequent assignments, whether they come from within that config file or from any other.


Creating or editing configuration files should only be attempted by experienced users.

The Add button opens a standard file browsing window, from which you can choose configuration files to add. The Remove button removes the configuration file that is highlighted.

The Move Up and Move Down buttons rearrange the order of the configuration files. Order is important. These files are read from the top down; variables change with each subsequent assignment, taking on the last value assigned.
