IEC TR 62541-1:2010

Specifies a generalized interface for efficient exchange of data. Takes into account the latencies caused by a local area network providing efficient data exchange also over local area networks. This publication is of core relevance for Smart Grid.

IEC 61970-402:2008(E) provides the base functionality considered necessary and common that is provided by neither the normative standards incorporated by reference nor the new APIs specified in the IEC 61970-403 to IEC 61970-449 generic interface standards. An application is expected to use the Common Services in conjunction with the generic interfaces. This publication is of core relevance for Smart Grid.

IEC 61970-403:2008(E) provides a generic request/reply-oriented data access mechanism for applications from independent suppliers to access CIM data in combination with IEC 61970-402. An application is expected to use the Generic Data Access (GDA) service as part of an initialisation process or an occasional information synchronization step. This publication is of core relevance for Smart Grid.

Specifies a generalized interface for efficient exchange of messages. Takes into account the latencies caused by a Local Area Network (LAN) providing efficient data exchange also over Local Area Networks. The Generic Eventing and Subscription API is expected to provide one of the primary means for accomplishing application integration. This publication is of core relevance for Smart Grid.

IEC TR 62541-1:2016(E) is a Technical Report and presents the concepts and overview of the OPC Unified Architecture (OPC UA). Reading this document is helpful to understand the remaining parts of this multi-part document set. Each of the other parts is briefly explained along with a suggested reading order. This second edition cancels and replaces the first edition of IEC TR 62541-1, published in 2010. This edition includes no technical changes with respect to the previous edition but includes updates to reflect changes or additions in normative parts of IEC 62541.
