Every OPC UA application (client or server) needs an application URI, which uniquely identifies the application instance in the system.

Applications based on QuickOPC determine their application URI in the following way:

  1. If the application manifest contains a non-empty ApplicationUriString property, it will be used as the application URI.
  2. Otherwise, the application URI is automatically generated, using a format string from the ApplicationUriFormat property in the application parameters.
