適用范圍：The IEC 61970-405 Generic Eventing and Subscription (GES) specification specifies ageneralized interface for efficient exchange of messages. The specification takes into accountthe latencies caused by a Local Area Network (LAN) providing efficient data exchange alsoover Local Area Networks. The Generic Eventing and Subscription (GES) API is expected toprovide one of the primary means for accomplishing application integration. Beyond the scopeof the GES API, other APIs address the high performance, real-time interactive needs of anapplication within a running system as well as request/reply oriented generic data access.IEC 61970-405 is derived from the Object Management Group (OMG) Data Acquisition fromIndustrial Systems section Alarms and Events (DAIS A&E) specification. OMG DAIS A&Erelies on the OMG Data Access Facility (DAF) and OPC Alarms and Events (A&E)specifications. OMG DAIS A&E is a Platform Specific Model (PSM) with CORBA as theplatform and OPC A&E is a PSM with Microsoft COM as the platform. Implementers wantingan introduction to OMG DAIS A&E and OPC A&E shall read these documents.The GES interface is intended to interoperate with other IEC 61970 based interfaces. Hence itis possible to use information retrieved from other interface to access the same informationusing this interface, for example:? object identifiers,? attribute names or identifiers,? class names or identifiers.The way data is organized in a server implementing the GES interface can be seen by usingthe browse interfaces for data and meta data. It is also possible to use the data accessinterface directly without using the browse interfaces if the client has an a priori knowledge ofobject, class and attribute identifiers. Object identifiers may be retrieved using data from otherinterfaces, for example a CIMXML file or the IEC 61970-404 interface. Information on whatclasses and attributes are available will be described in IEC 61970-45X documents.IEC 61970-405 describes the functionality in a technology independent way, it is a PlatformIndependent Specification (PIM). Hence, it explains the functionality to a level that can beused to create PSMs or be an introduction to existing PSMs, i.e. DAIS A&E and OPC A&E.Implementers wanting an introduction to OMG DAIS A&E and OPC A&E should read thesedocuments.IEC 61970-405 consists of two parts:? SCADA alarms and events that is the Platform Independent Specification (PIM) derivedfrom DAIS A&E and OPC A&E. This part is called “Generic Eventing and SubscriptionAlarms and Events” (GES A&E).? Generic messaging that is a generalization of the SCADA alarms and events. This part isjust called “Generic Eventing and Subscription” (GES).IEC 61970-1 provides the EMS-API reference model upon which this standard is based. Inthat reference model, the terminology used in this part of IEC 61970 is introduced and the roleof the CIS is explained.IEC 61970-401 provides an overview and framework for the CIS (IEC 61970-4XX)standards.IEC 61970-402 provides the base services to be used in conjunction with otherIEC 61970-4XX documents. This specification extends the Common Services to provide anevent subscription oriented mechanism for applications to exchange CIM data.The mapping of IEC 61970-405 to implementation specific technologies or Platform SpecificModels (PSMs) is further described in a separate series of documents, i.e. the futureIEC 61970-5XX. For actual implementations, the future IEC 61970-5XX, OMG DAIS A&E,OMG DAF or OPC A&E are used.
