6 Die_InterfaceType

6.1 Die_InterfaceType Definition

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).

The BrowseName of the object instance shall be “Die_<Manufacturer>_<SerialNumber>”.

Example: “Die_Erema_0123456”.

6.2 DeviceClass

The DeviceClass Property in the Identification Object inside the ExtrusionDeviceType shall have the value “Extruder die”.

6.3 Container objects

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

6.3.1 TemperatureZones

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

6.3.2 MeltPressures

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).

6.3.3 DimensionAdjustment

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”.
