Protocol support files provided for a device are exposed as Variables organised in the ProtocolSupport folder. They may represent various types of information as defined by a protocol. Examples are a GSD or a CFF file. The ProtocolSupport folder is formally defined in OPC UA for Devices 5.7.3.. The mapping is protocol independent. All the documents listed in NetworkData.DeviceInformationDocuments are mapped. The value of the <PlaceHolder> is defined by the label of the respective document (Document.Label).
