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.

The BrowseName of the object instance shall be “Extruder_<Manufacturer>_<SerialNumber>”
Example: “Extruder_Coperion_0123456”.
The DeviceClass Property in the Identification Object inside the ExtrusionDeviceType shall have the value “Extruder”.
This Property indicates to which extrusion line the extruder belongs to (e.g. “blown film line 2”)
The MachineConfigurationType is defined in OPC 40083 and provides information on the current configuration of a machine/device.
This Property indicates the Id of the barrel.
This Property indicates the Id of the screw.
These object give information about the main drive and additional drives of the extruder. The DrivesType and DriveType are defined in OPC 40083.
NOTE: Drives are independent from extruder zones. That means that e.g. the value of the vacuum shall be in the VacuumZones and also switching the vacuum shall be inside the VacuumZone. If a vacuum pump is modelled separately as additional drive, this is used for additional information (e.g. Energy).
Throughput of the extruder in mass per time (e.g. kg/h).
Specific output of the extruder in mass per revolution.
The UsersType is defined in OPC 40083 and provides information on the current users on the machine/device.
