This page lists the conformance units of the selected profile with their name and description.
Conformance units that are inherited via included Profiles are not listed by default. Use the following radio buttons to change this default behaviour.






Address Space Model
Include  Name Opt.  Description  From Profile  Test Cases
Address Space Client Base Uses and understands the NodeClasses with their Attributes and behaviour as defined in Part 3. This includes for instance: Object, ObjectType, Variable, VariableType, References and DataType. This includes treating BrowseNames and String NodeIds as case sensitive.   Open
Address Space Client Complex Data Dictionary Uses and understands arbitrary structured DataTypes via Data Dictionary. Note that V1.04 of OPC UA Part 3 specifies a simplified approach using the new DataTypeDefinition Attribute. The "Address Space Client DataTypeDefinition Attribute" Conformance Unit requires support of the DataTypeDefinition Attribute.   Open

Attribute Services
Include  Name Opt.  Description  From Profile  Test Cases
Attribute Client Read Base Use the Read Service to read one or more Attributes of one or more Nodes. This includes use of an IndexRange to select a single element or a range of elements when the Attribute value is an array.
Clients shall use bulk operations whenever possible to reduce the number of Service invocations.
  Open
Attribute Client Read with proper Encoding This ConformanceUnit refers to the ability of a Client to discover the available encodings and choose a specific one when calling the Read Service.   Open
Attribute Client Read Complex Read and decode Values with structured DataTypes.   Open

Data Access
Include  Name Opt.  Description  From Profile  Test Cases
Data Access Client Basic Understand the DataAccess Variable Types.
Make use of the standard Properties if applicable.
  Open
Data Access Client BaseAnalogType Understand BaseAnalogType Variables with corresponding Properties.   Open
Data Access Client AnalogItemType Understand AnalogItemType Variables with corresponding Properties.   Open
Data Access Client AnalogUnitType Understand AnalogUnitType Variables with corresponding Properties.   Open
Data Access Client AnalogUnitRangeType Understand AnalogUnitRangeType Variables with corresponding Properties.   Open
Data Access Client TwoState Understand TwoStateDiscreteType Variables with corresponding Properties.   Open
Data Access Client MultiState Understand MultiStateDiscreteType Variables with corresponding Properties.   Open
Data Access Client MultiStateValueDiscrete Understand MultiStateValueDiscreteType Variables with corresponding Properties.   Open
Data Access Client Deadband Use PercentDeadband to filter value changes of AnalogItemType Variables.   Open
Data Access Client SemanticChange Recognize the semantic change bit in the StatusCode while monitoring items and take proper action. Typically, the Client has to re-read Properties that define type-specific semantic like the EURange and EngineeringUnits Properties.   Open
