6 ExtrusionLine_InterfaceType

6.1 ExtrusionLine_InterfaceType Definition

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 Machines Object of the Server (see OPC UA for Machinery).

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”.

6.2 Optional childs in ExtrusionDeviceType

The SuperType ExtrusionDeviceType includes the optional Variables Target and Strand which are applicable only for the components of an extrusion line and not for the complete line represented by the ExtrusionLine_InterfaceType. Therefore, these variables shall not be used in the instances of ExtrusionLine_InterfaceType.

6.3 Components

Instances for all components of an extrusion line are located directly under the Machines Object in the server representing the component. If the server representing the extrusion line is an aggregating server also providing information for components of the extrusion line, the instances should be referred also by the Components Object according to OPC 40001-1 for easier access.

6.4 MachineMESConfiguration

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

6.5 MESMessage, SetMESMessage, ClearMESMessage

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.

6.6 Users

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

6.7 ConfigurationParameters

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:

7WeightDouble

Manufacturer dependent configuration parameters shall have an Id ≥ 100.

6.8 MaterialList

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.
