UA Part 15: Safety - 13 Profiles and Conformance Units

13 Profiles and Conformance Units

Figure 31 (informative) – Facets and Conformance Units of OPC UA Safety.

13.1 Conformance units

This clause defines the corresponding ConformanceUnits for the OPC UA Information Model for Safety.

Table 41 – Conformance Units for Safety

Category	Title	Description
Transport	SafetyACSet	An entry point for browsing a component implementing OPC UA Safety and finding its SafetyProviders and/or SafetyConsumers.
Transport	ReadSafetyData	Exchange of safety protocol data units using a method.
Transport	ReadSafetyDiagnostics	A diagnostic interface to a SafetyProvider and its communication with a SafetyConsumer.
Transport	SafetyPDUs	Exchange of safety protocol data units using OPC UA variables.
Transport	SafetyProviderParameters	An interface to query the parameters of a SafetyProvider.
Transport	SafetyConsumerParameters	An interface to query the parameters of a SafetyConsumer.
Transport	SafetyProviderMapper	An abstract conformance unit representing a mapper for the SafetyProvider. Support at least one of SafetyProviderServerMapper or SafetyProviderPubSubMapper.
Transport	SafetySupport	Support at least one of SafetyProvider Facet or SafetyConsumer Facet.
Transport	SafetyProviderStateMachine	Implement the SafetyProvider state machine behavior.
Transport	SafetyConsumerStateMachine	Implement the SafetyConsumer state machine behavior.

13.2.1 Profile list

Table 42 lists all Profiles defined in this document and defines their URIs.

Table 42 – Profile URIs for Safety

Profile	Description	URI
SafetyAutomationComponent Facet	Describes communication partners in a unidirectional safety link. A SafetyAutomationComponent can be a SafetyProvider (data source), a SafetyConsumer (data sink), or both.	http://opcfoundation.org/UA-Profile/Transport/SafetyAutomationComponent
SafetyProvider Facet	Describes a SafetyProvider, which is the data source of a unidirectional safety link.	http://opcfoundation.org/UA-Profile/Transport/SafetyProvider
SafetyProviderServer Mapper Facet	Describes how a SafetyProvider provides its data and diagnostic information using OPC UA methods.	http://opcfoundation.org/UA-Profile/Transport/SafetyProviderServerMapper
SafetyProviderPubSub Mapper Facet	Describes how a Safety provider provides its data using PubSub variables.	http://opcfoundation.org/UA-Profile/Transport/SafetyProviderPubSubMapper
SafetyConsumer Facet	Describes a SafetyProvider, which is the data sink of a unidirectional safety link. Note that no additional facets or conformance units are involved if the SafetyConsumer receives data from the SafetyProvider via method calls (thus acting as a client).	http://opcfoundation.org/UA-Profile/Transport/SafetyConsumer
SafetyConsumerPubSub Mapper Facet	Describes how a SafetyConsumer requests and receives data from a SafetyProvider using PubSub variables.	http://opcfoundation.org/UA-Profile/Transport/SafetyConsumerPubSubMapper
