The Resources Objectshall be used as the browse entry point for physical and logical resources of the device the Serveris running on. It shall reside in the Server Objectdefined in OPC 10000-5. It may contain a set of OrganizesReferences that point to other Objectsrepresenting specific resources. It is formally defined in Table 36.

The Communication Objectshall be used as the browse entry point for communication related resources of the physical device the Serveris running on. It is formally defined in Table 37.

The Communication Objectis referenced by an Organizes Referencefrom the Resources Objectdefined in 5.4.1.

The Communication Objectmay include the following subfolders:

• MappingTables
• NetworkInterfaces
• Streams

Note: It is recommended to keep TSN-Streams and possible future (DetNet-)Flows separated in specific folders.

The MappingTables Objectshall be used as the browse entry point for mapping tables of priority values and their application labels. It is formally defined in Table 39. All instances of the PriorityMappingTableTypeshall be referenced from this Object, either directly or indirectly, following hierarchical References.

The NetworkInterfaces folder is intended to hold instances, which are of IetfBaseNetworkInterfaceType or a subtype of it. However other Objectscan be stored within this folder that implement the UA Interface IIetfBaseNetworkInterfaceType.

All Objectsof Type IetfBaseNetworkInterfaceTypewithin the NetworkInterfacesfolder shall represent either a physical or virtual network interface.

The Streams Objectshall be used as the browse entry point for network streams of the device the Serveris running on. It is formally defined in Table 40.
