DataTypes for Connection Manager Configuration – OPC Unified Architecture – Part 81: UAFX Connecting Devices and Information Model

F.1 DataTypes for Connection Manager Configuration

F.1.1 Overview

This section describes DataTypes that can be used to serialise the Objects that compose a ConnectionConfigurationSet (see 6.8 and 6.10) into a single structure (ConnectionConfigurationSetDataType). The ConnectionConfigurationSetDataType can, for example, be used for persisting a ConnectionConfigurationSet, for storing it within a File (see F.2), or for maintaining the configuration of a ConnectionManager (see F.3).

For the base principles used for the mapping, see clause F.1.2.

Figure F.1 depicts the different components of the ConnectionConfigurationSetDataType and their relation to each other.

Figure F.1 – ConnectionConfigurationSet serialisation

F.1.2 Base principles

F.1.2.1 References

References between Objects in different Object lists are mapped using an array index field for the related structure array. For example, the AutomationComponentConfigurationDataType has ServerAddressIndex that contains an index into the ServerAddress in the ConnectionConfigurationSetConfDataType. Indices are defined as Int32; a negative number indicates no Reference exists.

F.1.2.2 Namespaces

OPC UA uses Namespaces, and in a defined scope, all identifiers (NodeId, QualifiedName) use a NamespaceIndex instead of a NamespaceUri. The scope has a NamespaceArray with URIs where the NamespaceIndex is defined as an index into this array. For a Server, the scope is the complete Server. For a UANodeSet XML file, it is the file.

A ConnectionConfigurationSet (see 6.8.2) contains node identifiers related to different scopes, as illustrated in Figure F.2. In this illustration, the ConnectionConfigurationSet contains information for two different Servers. Node identifiers in the Information Model for the ConnectionManager (i.e., an instance of ConnectionConfigurationSetType) use PortableNodeIdentifier (see 10.36) to support the resolution for the dedicated scope (see also 13.3).

Figure F.2 – Scopes within a ConnectionConfigurationSet

To reduce the overall size of the DataTypes defined in this Clause (i.e. ConnectionConfigurationSetConfDataType), NodeId, AliasName and RelativePath are used instead of their portable version. The scope of those identifiers is defined by the related ServerAddressConfDataType structure, containing a Namespace array. The NamespaceIndex of a node identifier is used as an index into the Namespace array of the related ServerAddressConfDataType.

A ConnectionManager can map NodeId and RelativePath contained in the DataTypes to their portable versions using the NamespaceUri from the Namespace array when it loads the ConnectionConfigurationSet from the data structure.

F.1.2.3 SelectionListType

There is no generic DataType defined to represent a SelectionListType Variable. A generic definition would create additional overhead since the values can have different DataTypes.

To simplify the handling of SelectionListType, each Variable that is of SelectionListType is mapped to:

A Structure field with the corresponding DataType representing the current value. The field name is constructed from the Variable name (<Variable name>).

A Structure field with an array of the corresponding DataType representing the additional selection options (selectable values associated with the selection list – the list can contain only the current value if this selection list currently does not provide for modifications). The field name is constructed from the Variable name with a ‘Selection’ suffix (<Variable name>Selection).

A Structure field with DataType Boolean indicates if the list of selectable values is editable by a Client. The field is omitted if the specification requires that RestrictToList is set to TRUE (i.e. no values can be entered; only a selection is possible). The field name is constructed from the Variable name with a ‘Modify’ suffix (<Variable name>Modify).

F.1.2.4 Extensibility

Structured DataTypes can only be extended by subtyping. This is a problem if Structures are embedded into other Structures, e.g., the ConnectionConfigurationSet-related Structure has an array of AutomationComponent-related Structures. Therefore, each Structure has an additional field with an array of KeyValuePairs that can be used for potential future standardised or vendor-specific extensions.

F.1.2.5 Optional fields

Connection configuration and communication flow-related configuration Structures use Structures with optional fields to handle the optional Variables.

In other configuration Structures, AllowSubtypes is needed. Since AllowSubtypes cannot be combined with IsOptional, optional handling is done with empty arrays or null values for the used DataType.

F.1.3 ConnectionConfigurationSetConfDataType

This Structure DataType is used to hold the information for a ConnectionConfigurationSet.

It is semantically equivalent to the ConnectionConfigurationSetType as defined in 6.8.2, with the exception that the elements ConnectionConfigurationSetStateMachine, Edit, and Lock, as defined in the ConnectionConfigurationSetType, are not part of this DataType. If this DataType is converted to an Object, the ConnectionConfigurationSetStateMachine shall be in State Ready, the Edit shall be set to False, and the Lock shall be assigned to the ConnectionManager.

The ConnectionConfigurationSetConfDataType is formally defined in Table F.1.

F.1.16 NodeIdentifierValuePair

The NodeIdentifierValuePair is used to provide a key-value pair where the key is a Variable Node.

It is semantically equivalent to the PortableKeyValuePair as defined in 10.35 with the optimisation as described in F.1.2.2.

The NodeIdentifierValuePair DataType is formally defined in Table F.28.

Table F.28 – NodeIdentifierValuePair structure

Name	Type	Description
NodeIdentifierValuePair	Structure	Subtype of Structure defined in OPC 10000-5
Key	4:NodeIdentifier	The Key to the Variable.
ArrayIndex	0:UInt32[]	If Key refers to a Variable with ValueRank >= 1, the ArrayIndex specifies the index for a specific value referenced by Key (Not the entire array, but a specific element in it). The ArrayIndex is required to have the same dimension as the dimension of the node. If Key is not of array type, or if no specific index shall be referenced, then the array shall be null or empty.
Value	0:BaseDataType	The value associated with the key/array item.

The NodeIdentifierValuePair representation in the AddressSpace is formally defined in Table F.29.

F.1.17 NodeIdTranslationConfDataType

This NodeIdTranslationConfDataType is used to provide table entries for the conversion of NodeId to NodeIdentifier (see F.1.15).

It is semantically equivalent to the NodeIdTranslationDataType as defined in 10.33 with the optimisation as described in F.1.2.2.

The NodeIdTranslationConfDataType is formally defined in Table F.30.

Table F.30 – NodeIdTranslationConfDataType structure

Name	Type	Description
NodeIdTranslationConfDataType	Structure	Subtype of Structure defined in OPC 10000-5
NodePlaceholder	0:NodeId	NodeId to be converted to the result of resolving the NodeIdentifier.
Node	4:NodeIdentifier	Specifies the NodeIdentifier corresponding to the NodeId of the NodePlaceholder.

The NodeIdTranslationConfDataType representation in the AddressSpace is formally defined in Table F.31.

F.1.18 AddressSelectionDataType

The AddressSelectionDataType holds the selection list for a network address (see F.1.2.3). It allows the address selection to be optional, where this DataType is used (see F.1.7 and F.1.8).

The AddressSelectionDataType is formally defined in Table F.32.

Table F.32 – AddressSelectionDataType structure

Name	Type	Description	Allow Subtypes
AddressSelectionDataType	Structure	Subtype of Structure defined in OPC 10000-5
Address	0:NetworkAddressDataType	Network address configured.	True
AddressSelection	0:NetworkAddressDataType[]	Selection list options for Address.	True
AddressModify	0:Boolean	Flag indicating if the Address options can be modified.	False

The AddressSelectionDataType representation in the AddressSpace is formally defined in Table F.33.

F.1.19 ReceiveQosSelectionDataType

The ReceiveQosSelectionDataType holds the selection list for a receive QoS configuration (see F.1.2.3). It allows making the receive QoS selection optional, where this DataType is used (see F.1.7 and F.1.8).

The ReceiveQosSelectionDataType is formally defined in Table F.34.

Table F.34 – ReceiveQosSelectionDataType structure

Name	Type	Description	Allow Subtypes
ReceiveQosSelectionDataType	Structure	Subtype of Structure defined in OPC 10000-5
ReceiveQos	0:ReceiveQosDataType[]	The ReceiveQos configuration.	True
ReceiveQosSelection	0:BaseDataType	Selection list options for ReceiveQos. The field will contain a matrix of subtypes of ReceiveQosDataType. If the field is not provided, it is null.	False
ReceiveQosModify	0:Boolean	Flag indicating if the ReceiveQos options can be modified.	False

The ReceiveQosSelection is of BaseDataType and thus requires a subtype to be used. The flag AllowSubtypes is only set if the type can be used as well as subtypes.

The ReceiveQosSelectionDataType representation in the AddressSpace is formally defined in Table F.35.
