9.2 OPC UA Conformance Units and Profiles ToC Previous Next

This chapter defines the corresponding profiles and conformance units for the OPC UA Information Model for POWERLINK Profiles are named groupings of conformance units. Facets are profiles that will be combined with other Profiles to define the complete functionality of an OPC UA Server or Client. The following tables specify the facets available for Servers that implement the POWERLINK Information Model companion standard, and for Clients that are communicating with such Servers.

Table 51 defines a server facet for direct access to the POWERLINK Objects through a structured NodeId that may be generated by user entry or by tools.

Table 51 – POWERLINK Direct Access Server Facet Definition

Conformance Unit Description Optional/
Mandatory
POWERLINK BinaryAddress Supports generic access to POWERLINK Objects using opaque NodeIds M
POWERLINK StringAddress Supports generic access to POWERLINK Objects using string NodeIds M
Profiles    
Core Server Facet M  
Embedded DataChange Subscription Server Facet O  

Table 52 defines a client facet for direct access to the POWERLINK Objects through a structured NodeId that may be generated by user entry or by tools.

Table 52 – POWERLINK Direct Access Client Facet Definition

Conformance Unit Description Optional/
Mandatory
POWERLINK DirectAccessClient Use services like Attribute Read or Attribute Write to access POWERLINK Objects through constant NodeIds M
Profiles    
Core Client Facet M  
Attribute Read Client Facet M  
Attribute Write Client Facet O  
DataChange Subscriber Client Facet O  

Table 53 defines a server facet for access to POWERLINK Objects of the communication profiles EPSG DS 301 and EPSG DS302 through the OPC UA Information Model.

Table 53 – POWERLINK Communication Profile Server Facet Definition

Conformance Unit Description Optional/
Mandatory
POWERLINK CommunicationProfileServer Supports the Information Model for the communication profile EPSG DS 301 and EPSG DS 302 M

DeviceCommunication_Server_Facet (defined in OPC 10000-100) M  

Table 54 defines a client facet for access to POWERLINK Objects of the communication profiles EPSG DS 301 and EPSG DS302 through the OPC UA Information Model.

Table 54 – POWERLINK Communication Profile Client Facet Definition
