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.

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.

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.
