5 Use cases
OPC 40084-11 describes the data exchange interface for corrugators as part of an extrusion line. The interface is used by
MES (Manufacturing Execution System) for collecting the information generated by extrusion lines at a central point for easier quality assurance and job and dataset management.
Line controllers to monitor and set process parameters.
6 Corrugator_InterfaceType
6.1 Corrugator_InterfaceType Definition
This OPC UA ObjectType is used for the root Object representing a corrugator as part of an extrusion line. It is based on the HaulOff_InterfaceType (defined in OPC 40084-4) and formally defined in Table 1.
The instance(s) of Corrugator_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 corrugator so only one instance of Corrugator_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 Corrugator_InterfaceType will be created.

6.4 ExtruderEnabled
This Property describes, if the (main) extruder is allowed to run. This information is mainly for the MES. The signal to the extruder is usually a hardware/bus signal.

8 Namespaces
8.1 Namespace Metadata
Table 5 defines the namespace metadata for this specification. The Object is used to provide version information for the namespace and an indication about static Nodes. Static Nodes are identical for all Attributes in all Servers, including the Value Attribute. See Part 5 for more details.
The information is provided as Object of type NamespaceMetadataType. This Object is a component of the Namespaces Object that is part of the Server Object. The NamespaceMetadataType ObjectType and its Properties are defined in Part 5.
The version information is also provided as part of the ModelTableEntry in the UANodeSet XML file. The UANodeSet XML schema is defined in Part 6.

8.2 Handling of OPC UA Namespaces
Namespaces are used by OPC UA to create unique identifiers across different naming authorities. The Attributes NodeId and BrowseName are identifiers. A Node in the UA AddressSpace is unambiguously identified using a NodeId. Unlike NodeIds, the BrowseName cannot be used to unambiguously identify a Node. Different Nodes may have the same BrowseName. They are used to build a browse path between two Nodes or to define a standard Property.
Servers may often choose to use the same namespace for the NodeId and the BrowseName. However, if they want to provide a standard Property, its BrowseName shall have the namespace of the standards body although the namespace of the NodeId reflects something else, for example the EngineeringUnits Property. All NodeIds of Nodes not defined in this document shall not use the standard namespaces.
Table 6 provides a list of mandatory and optional namespaces used in an OPC 40084-11 OPC UA Server.
| NamespaceURI | Description | Use |
| http://opcfoundation.org/UA/ | Namespace for NodeIds and BrowseNames defined in the OPC UA specification. This namespace shall have namespace index 0. | Mandatory |
| Local Server URI | Namespace for nodes defined in the local server. This may include types and instances used in a device represented by the server. This namespace shall have namespace index 1. | Mandatory |
| http://opcfoundation.org/UA/DI/ | Namespace for NodeIds and BrowseNames defined in OPC 10000-100. The namespace index is server specific. | Mandatory |
http://opcfoundation.org/UA/PlasticsRubber/ GeneralTypes/ | Namespace for NodeIds and BrowseNames defined in OPC 40083. The namespace index is server specific. | Mandatory |
http://opcfoundation.org/UA/PlasticsRubber/ Extrusion_v2/GeneralTypes/ | Namespace for NodeIds and BrowseNames defined in OPC 40084-1. The namespace index is server specific. | Mandatory |
| http://opcfoundation.org/UA/Machinery/ | Namespace for NodeIds and BrowseNames defined in OPC 40001-1. The namespace index is server specific. | Mandatory |
http://opcfoundation.org/UA/PlasticsRubber/ Extrusion_v2/HaulOff/ | Namespace for NodeIds and BrowseNames defined in OPC 40084-4. The namespace index is server specific. | Mandatory |
http://opcfoundation.org/UA/PlasticsRubber/ Extrusion_v2/Corrugator/ | Namespace for NodeIds and BrowseNames defined in this specification. The namespace index is server specific. | Mandatory |
| Vendor specific types and instances | A server may provide vendor specific types like types derived from MachineType or MachineStatusType or vendor specific instances of devices in a vendor specific namespace. | Optional |
Table 7 provides a list of namespaces and their index used for BrowseNames in this specification. The default namespace of this specification is not listed since all BrowseNames without prefix use this default namespace.
| NamespaceURI | Namespace Index | Example |
| http://opcfoundation.org/UA/ | 0 | 0:NodeVersion |

9 (normative)OPC 40084-11 Namespace and mappings
Namespace and identifiers for OPC 40084-11 Information Model
This appendix defines the numeric identifiers for all of the numeric NodeIds defined in this specification. The identifiers are specified in a CSV file with the following syntax:
<SymbolName>, <Identifier>, <NodeClass>Where the SymbolName is either the BrowseName of a Type Node or the BrowsePath for an Instance Node that appears in the specification and the Identifier is the numeric value for the NodeId.
The BrowsePath for an Instance Node is constructed by appending the BrowseName of the instance Node to the BrowseName for the containing instance or type. An underscore character is used to separate each BrowseName in the path. Let’s take for example, the MachineInformationType ObjectType Node which has the ControllerName Property. The Name for the ControllerName InstanceDeclaration within the MachineInformationType declaration is: MachineInformationType_ControllerName.
The NamespaceUri for all NodeIds defined here is http://opcfoundation.org/UA/PlasticsRubber/Extrusion_v2/Corrugator/
The CSV released with this version of the specification can be found here:

A computer processible version of the complete Information Model defined in this specification is also provided. It follows the XML Information Model schema syntax defined in Part 6.
