A ConformanceUnit represents an individually testable entity. For improved clarity, the large list of ConformanceUnits is arranged into named ConformanceGroups. These groups reflect the Service Sets in OPC 10000-4 and the OPC UA information models. Table 2 lists the ConformanceGroups. These groups and the ConformanceUnits that they describe are detailed in the Subclauses of chapter 5 starting with clause 5.2. ConformanceGroups have no impact on testing; they are used only for organizational reasons, i.e. to simplify the readability of this document.
|
Group |
Description |
|
Address Space Model |
Defines ConformanceUnits for various features of the OPC UA AddressSpace. |
|
Aggregates |
All ConformanceUnits that are related to Aggregates, including individual ConformanceUnits for each supported Aggregate as described in Part 13. |
|
Alarms and Conditions |
All ConformanceUnits that are associated with the OPC UA Information Model for Conditions, acknowledgeable Conditions, confirmations and Alarms as specified in Part 9. |
|
Includes ConformanceUnits to read or write current or historical Attribute values. |
|
|
Auditing |
User level security includes support for security audit trails, with traceability between Client and Server audit logs. |
|
Base Information |
All information elements as defined in Part 5. |
|
Data Access |
ConformanceUnits specific to Clients and Servers that deal with the representation and use of automation data as specified in Part 8. |
|
ConformanceUnits which focus on Server Endpoint Discovery. |
|
|
GDS |
Conformance Units for a GDS. Includes units for global discovery and global certificate management. |
|
Historical Access |
|
|
Methods represent the function calls of Objects. Methods are invoked and return only after completion (successful or unsuccessful). |
|
|
Miscellaneous |
This group contains ConformanceUnits that cover miscellaneous subjects, such as recommended behaviours, documentation etc. These ConformanceUnits typically do not fit into any of the other groups. |
|
Monitored Item Services |
Clients define MonitoredItems to subscribe to data and Events. Each MonitoredItem identifies the item to be monitored and the Subscription to use to send Notifications. |
|
Bundles ConformanceUnits for all Services to add and delete OPC UA AddressSpace Nodes and References. |
|
|
Protocol and Encoding |
Covers all transport and encoding combinations that are specified in Part 6. |
|
Redundancy |
The design of OPC UA ensures that vendors can create redundant Clients and redundant Servers in a consistent manner. Redundancy may be used for high availability, fault tolerance and load balancing. |
|
Security |
Security related ConformanceUnits that can be profiled this includes all aspects of security. |
|
An (OPC UA) Session is an application layer connection. |
|
|
Subscriptions are used to report Notifications to the Client. |
|
|
View Services |
Clients use the View Service Set to navigate through the OPC UA AddressSpace or through a View (a subset) of the OPC UA AddressSpace. |
