6.1 TCD_InterfaceType Definition

This OPC UA ObjectType is used for the root Object representing a TCD with its subcomponents. It is formally defined in Table 1.

NOTE: To promote interoperability of Clients and Servers, all instantiated Devices shall be aggregated in an Object called “DeviceSet” (see OPC UA for Devices)

The BrowseName of the object instance shall be "TCD_<Manufacturer>_<SerialNumber>"

Example: "TCD_HB-Therm_0123456".

Some TCD have several device zones (see 0). For these, the OPC UA server needs to create several instances of the TCD_InterfaceType. As the TCD has only one serial number, the BrowseNames of the objects shall include an extension e.g. “TCD_Wittmann_634_a” and “TCD_Wittmann_634_b”.

NOTE: The namespace of this BrowseName is the local server URI with namespace index 1 or a vendor specific namespace with server specific namespace index (see Table 28). The BrowseNames of the nodes below are in the namespace of the specification where used Type is defined.

Examples:
