B2MML Mapping (Informative)

Overview

This annex provides a mapping of the OPC UA ISA-95 information model to B2MML; conversely it also provides a mapping from B2MML to the OPC UA ISA-95 information model. This section is informative only in that B2MML is not a standard and as such multiple variation of it may exist. This mapping is for a common version, but may not apply to all implementation of B2MML.

ISA95HierarchyScopeType

The ISA95HierarchyScopeType is a concrete VariableType that can be used directly. It is a subtype of BaseDataVariableType

This VariableType indicates where the exchanged information fits within the role base equipment hierarchy defined in ISA-95. It defines the scope of the exchanged information, such as a site or area for which the information is relevant.

ToEquipmentScope		Object	<Equipment>		ISA95EquipmentType	Optional

OtherValue defines a customized hierarchy scope. If Value attribute is set to “OTHER_14”, then OtherValue shall be identification of the hierarchy scope.

SubScope indicates a sub hierarchy definition.

<Equipment> defines an ISA95EquipmentType Object that this variable is associated with.

ToEquipmentScope

The ToEquipmentScope is a concrete ReferenceType that can be used directly. It is a subtype of NonHierarchicalReferences.

Subtype of NonHierarchicalReferences ReferenceType defined in OPC 10000-5

This ReferenceType is used to describe the Equipment that an ISA95HierarchyScope variable is to be associated with.

The SourceNode of this ReferenceType shall be a Variable or VariableType of ISA95HierarchyScopeType or its subtype

The TargetNode of this ReferenceType shall be an Object of ISA95EquipmentType or its subtype.

Company

The following definition illustrates what a company definition may look like. This definition will be used in examples of the ISA-95 information model, but another implementation may choose to represent the information a different manner. In some systems it maybe simply is a reference to some other system that contains the actual company information.

The company information includes address information of the company. This information is available both as a dataType (see Table 132 and Table 133) and as a VariableType (see Table 134).. This combination allows the information to access as a block or individually.

Table 132 – AddressDataType Structure

Name	Type	Description
AddressDataType	Structure	Information that describes an address.
Street	LocalizedText	The street
City	LocalizedText	The city
State	LocalizedText	The state or region
Country	LocalizedText	The country
PostalCode	LocalizedText	The postal code

Its representation in the AddressSpace is defined in a below table.

HasProperty	Variable		Country	LocalizedText	BaseDataVariableType	Mandatory
HasProperty	Variable		PostalCode	LocalizedText	BaseDataVariableType	Mandatory
HasProperty	Variable		Street	LocalizedText	BaseDataVariableType	Mandatory

The company include contact information for key personnel at the company. This information is available both as a DataType and as a variable type. This combination allows the information to access as a block of individually.

This is an example of a possible Company sub-type. It is used in examples since it provides more information and is more typical of what an actual user would require.

UML notation used in ISA-95 (Informative)

The ISA-95 object models are illustrated using the Unified Modelling Language (UML) notational methodology, as defined in ISA/IEC 19501.

Table 139 - UML notation used in ISA-95

Symbol Name	Symbol	Definition
UMLPackage		Defines a package, a collection of object models, state models, use cases, and other UML models. Packages are general-purpose grouping mechanisms used to organize semantically related model elements. In this standard a package is used to specify an external model, such as a production rule model, or a reference to another part of the model.
UMLClass		Represents a UML class of objects, each with the same types of attributes. Each object is uniquely identifiable or enumerable. No operations or methods are listed for the classes.
UMLAssociation		An association between elements of a class and elements of another or the same class. Each association is identified. May have the expected number or range of members of the subclass, when ‘n’ indicates an indeterminate number. For example, 0..n means that zero or more members of the subclass may exist.
UMLGeneralization		Generalization (arrow points to the super class) shows that an element of the class is a specialized type of the super class.
UMLDependence		Dependence is a weak association that shows that a modelling element depends on another modelling element. The item at the tail depends on the item at the head of the relationship.
UMLAggregation		Aggregation (made up of) shows that an element of the class is made up of elements of other classes.
UMLCompositie		Composite shows a strong form of aggregation, which requires that a part instance be included in at most one composite at a time and that the composite object has sole responsibility for disposition of its parts.

Notation Extensions

Overview

The definition of the notation used in figures in this standard is described in OPC 10000-3. The following section describes some extension to this notation to allow for the illustration of structured DataTypes

Node Type Notation

DataTypeElement graphical extension is represented by the graphical form defined in Table 140

Table 140 - Notation of Nodes depending on the NodeClass

NodeClass	Graphical Representation	Comment
DataTypeElement		Gray pentagon including text representing the string-part of the DisplayName of the DataTypeElement.

Reference Notation

Table 141 defines an extension that illustrates the elements that are part of a DataType.

Table 141 - Simple Notation of Nodes depending on the NodeClass

ReferenceType	Graphical Representation	Comment
DataItem		This construct is used to link a DataType to the DataTypeElement that the structured data type is composed of.
