As a special case of Method calls, the standardized file transfer of OPC UA can be used to provide larger changes of the AddressSpace. This is useful, when many things need to change in the AddressSpace in one atomic operation, and not just individual instances or a small set of Nodes based on a TypeDefinition.

OPC 10000-14 provides this approach as well for larger changes of the PubSub Configuration. The PubSubConfigurationType is a subtype of the FileType defined in OPC 10000-20 and allows to either read a whole PubSubConfiguration or deploy a new configuration to the server. A specific file format is used for this case. Depending on the use case, different file formats may be used, for example, when downloading a recipe to a machine.
