This OPC UA ObjectType is used for the root Object representing an extrusion line as overall system. It is formally defined in Table 1.

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

NOTE: In most cases the OPC UA server will be implemented in the line control of the extrusion line so only one instance of ExtrusionLine_InterfaceType will be created. But it is also possible that one OPC UA server is connected to several extrusion lines as one interface to the MES. In this case several instances of ExtrusionLine_InterfaceType will be created.

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

Example: "ExtrusionLine_battenfeld_4".

This Property is the identifier of the extrusion line. Components (extruders, dies, winders, …) use the LineId to indicates to which extrusion line they belong to (e.g. “blown film line 2”).

This Property represents the current status of the extrusion line. Possible values are defined in ProductionStatusEnumeration of OPC 40083.

NOTE: For extrusion lines the status START_UP_2 shall also apply during material/product change, cleaning, shutting down. DRY_RUN_5 is not applicable for extrusion lines.

The MachineInformationType is defined in OPC 40083 and provides basic information on a machine/device.

The DeviceClass Property in the MachineInformation Object shall have the value "ExtrusionLine".

The MachineConfigurationType is defined in OPC 40083 and provides information on the current configuration of a machine/device.

The MachineMESConfigurationType is defined in OPC 40083. Here a list of standstill reasons for later selection by the operator can be defined.

The Object MESMessage and the methods SetMESMessage, ClearMESMessage are defined in OPC 40083 and used for sending text message from the MES to be shown on the machine.

NOTE: The Object MESMessage and the methods SetMESMessage, ClearMESMessage are taken out of the MachineMESStatusType, because not all functionalities defined there are relevant for extrusion lines.

The UsersType is defined in OPC 40083 and provides information on the current users on the machine/device.

The ConfigurationParameters Property contains a list of parameters, that can be used within the job description to configure the production of the extrusion line. The ConfigurationParametersType is defined in OPC 40083.

The following configuration parameters are standardized for OPC 40084-2:

Table 2 – Standardized configuration parameters for OPC 40084-2

Id	Name (for English version of LocalizedText)	DataType
1	Length	Double
2	Width	Double
3	Thickness	Double
4	Diameter	Double
5	Wall thickness	Double
6	Pieces	Double
7	Weight	Double

Manufacturer dependent configuration parameters shall have an Id ≥ 100.

This Object is used to provide a list of materials which are intended to be used on the extrusion line.

The MaterialListType is defined in OPC 40083.
