The Direct-Loading option provides a model where the installation is part of the transfer. To support the Direct-Loading model the Server has to provide the Current Version. This includes parameters like the version number, a release date or patch identifiers. With this information the Client can decide if an update is required and which version to install.

The Software Package is transferred using the TemporaryFileTransferType (OPC 10000-5). This includes the installation itself so that the installation option is not used.

For Direct-Loading the DirectLoadingType is used, which is described in 8.4.4.
