This specification defines the OPC Unified Architecture (OPC UA) Services. The Servicesdescribed are the collection of abstract Remote Procedure Calls (RPC) that are implemented byOPC UA Servers and called by OPC UA Clients. All interactions between OPC UA Clients andServers occur via these Services. The defined Services are considered abstract because noparticular RPC mechanism for implementation is defined in this part. IEC 62541-6 specifies one ormore concrete mappings supported for implementation. For example, one mapping in IEC 62541-6is to XML Web Services. In that case the Services described in this part appear as the Webservice methods in the WSDL contract.Not all OPC UA Servers will need to implement all of the defined Services. IEC 62541-7 definesthe Profiles that dictate which Services need to be implemented in order to be compliant with aparticular Profile.
