This OPC UA ObjectType is used for the root Object representing an extruder as part of an extrusion line. It is based on the ExtrusionDeviceType (defined in OPC 40084-1) and formally defined in Table 1.

The instance(s) of Extruder_InterfaceType shall be located under the Machines Object of the Server (see OPC UA for Machinery).

NOTE: If the OPC UA server is implemented in the control of the extruder so only one instance of Extruder_InterfaceType will be created. But it is also possible that one OPC UA server is connected to several machine controls as one interface to the MES. In this case several instances of Extruder_InterfaceType will be created.
