This OPC UA ObjectType is used for the root Object representing a die 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 Die_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 die so only one instance of Die_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 Die_InterfaceType will be created.

The BrowseName of the object instance shall be “Die_<Manufacturer>_<SerialNumber>”.
Example: “Die_Erema_0123456”.
The DeviceClass Property in the Identification Object inside the ExtrusionDeviceType shall have the value “Extruder die”.
Several objects can occur several times in a die (e.g. temperature zones). For these the following container objects are defined (see container concept in OPC 40083):
- TemperatureZones
- MeltPressures
- DimensionAdjustment
This ObjectType is a container for the temperature zones in the filter. The ExtrusionTemperatureZonesType is defined in OPC 40084-1.
This Object represents the pressures in the melt. The MeasuringDevicesType is defined in OPC 40083.
When instances for melt pressures are created, the BrowseNames shall be “MeltPressure_<Nr>” where <Nr> is a three-digit number with leading zeros, starting with “001”.
The pressure of the melt shall be delivered in bar or lbf/in² (=psi).
This Object is a container for the dimension adjustments devices of the die. The MeasuringDevicesType is defined in OPC 40083.
When instances for the dimension adjustment devices are created, the BrowseNames shall be “DimensionAdjustment_<Nr>” where <Nr> is a three-digit number with leading zeros, starting with “001”.
