適用范圍：The IEC 61970-407 Time Series Data Access (TSDA) specification specifies a generalized interfacefor efficient exchange of data. The specification takes into account the latencies caused by a LocalArea Network (LAN) providing efficient data exchange also over Local Area Networks.IEC 61970-407 is derived from the Object Management Group (OMG) Historical Data Access fromIndustrial Systems (HDAIS) specification. OMG HDAIS relies on the OMG Data Access Facility(DAF) and OPC Historical Data Access (HDA) specifications. OMG HDAIS is a Platform SpecificModel (PSM) with CORBA as the platform and OPC HDA is a PSM with Microsoft COM as theplatform. The IEC 61970-407 specification describes the functionality of these PSMs in a technologyindependent way (i.e., as a Platform Independent Model (PIM)). Hence, it explains the functionalityto a level that can be used to create additional PSMs or be an introduction to existing PSMs, i.e.HDAIS and OPC HDA. Implementers wanting an introduction to OMG HDAIS and OPC HDA shouldread these documents.The TSDA interface is intended to interoperate with other IEC 61970 based interfaces. Hence, it ispossible to use information retrieved from other interface to access the same information using thisinterface, 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 using thebrowse interfaces for data and meta data. It is also possible to use the data access interface directlywithout using the browse interfaces if the client has an a priori knowledge of object, class andattribute identifiers. Object identifiers may be retrieved using data from other interfaces, for examplea CIMXML file or the IEC61970-404 interface. Information on what classes and attributes areavailable will be described in IEC 61970-45X documents, for example historical SCADA data,historical State Estimator results etc.IEC61970-1 provides the EMS-APl reference model upon which this standard is based. In thatreference model, the terminology used in this part of IEC 61970 is introduced and the role of the CISis 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 further describedin a separate series of documents, i.e. the future IEC 61970-5XX. For actual implementations thefuture IEC 61970-5XX, OMG HDAIS, OMG DAF or OPC HDA are used.
