適用范圍：The IEC 61970-407 Time Series Data Access (TSDA) specification specifies a generalizedinterface for efficient exchange of data. The specification takes into account the latenciescaused by a Local Area Network (LAN) providing efficient data exchange also over Local AreaNetworks.IEC 61970-407 is derived from the Object Management Group (OMG) Historical Data Accessfrom Industrial Systems (HDAIS) specification. OMG HDAIS relies on the OMG Data AccessFacility (DAF) and OPC Historical Data Access (HDA) specifications. OMG HDAIS is aPlatform Specific Model (PSM) with CORBA as the platform and OPC HDA is a PSM withMicrosoft COM as the platform. The IEC 61970-407 specification describes the functionality ofthese PSMs in a technology independent way (i.e., as a Platform Independent Model (PIM)).Hence, it explains the functionality to a level that can be used to create additional PSMs or bean introduction to existing PSMs, i.e. HDAIS and OPC HDA. Implementers wanting anintroduction to OMG HDAIS and OPC HDA should read these documents.The TSDA interface is intended to interoperate with other IEC 61970 based interfaces. Hence,it is 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.Subclause 4.6 provides a generic mapping for the CIM classes and attributes.The way data is organized in a server implementing the TSDA 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, forexample historical SCADA data, historical State Estimator results etc.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.The mapping of IEC 61970-407 to implementation specific technologies or PSMs is furtherdescribed in a separate series of documents, i.e. the future IEC 61970-5XX. For actualimplementations the future IEC 61970-5XX, OMG HDAIS, OMG DAF or OPC HDA are used.
