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.
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:
| 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.
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.
