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 Atomicity Access the NonatomicRead or NonatomicWrite flags in the AccessLevelEx Attribute of Variable Nodes to determine whether Read or Write operations can be performed in atomic manner. This information will typically be shown to a user for further action.   Open
Address Space Client Full Array Only Access the WriteFullArrayOnly flag in the AccessLevelEx Attribute of Variable Nodes with non-scalar data types to determine whether writing to an array with an IndexRange is allowed.   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" ConformanceUnit requires support of the DataTypeDefinition Attribute.   Open
Address Space Client DataTypeDefinition Attribute Uses and understands arbitrary structured DataTypes where the meta data and encoding information are exposed with the StructureDefinitionType via 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.
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
