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

Example: "Pelletizer_Erema_0123456".

The instance(s) of Pelletizer_InterfaceType shall be located under the DeviceSet Object of the Server (see OPC UA Part 100).

NOTE: If the OPC UA server is implemented in the control of the pelletizer so only one instance of Pelletizer_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 Pelletizer_InterfaceType will be created.

The DeviceClass Property in the MachineInformation Object inside the ExtrusionDeviceType shall have the value "Pelletizer".

This object gives information about the drive of the pelletizer. The DriveType is defined in OCP 40083.

This Property describes the position of the pelletizer (Open/Closed).

This Property describes the WaterFlow of the Pelletizer. This is just a Flow Switch, if the WaterFlow is active or not.

This Property describes the distance between the rotation knife and the fixed knife.

This ObjectType is a container for the temperature zones at the corrugator.The ExtrusionTemperatureZonesType is defined in OPC 40084-1.

This Object is a container for possible additional measuring devices.

The KnifePackageType gives Information of the setup of the knife package. It consists of a fixed amount of knifes from a certain type.
