IEC 61850-7-1 gives an overview of this communication architecture.The part IEC 61850-7-3 defines common attribute types and common data classes related to substation applications. The attributes of the common data classes may be accessed using services defined in IEC 61850-7-2.These common data classes are used in part IEC 61850-7-4 to define the compatible data classes To reach interoperability all data to be exchanged need a strong definition with regard to syntax and semantic.The semantic of the data is mainly provided by names assigned to logical nodes and data they contain as defined in the part IEC 61850-7-4. It should be noted that data with full semantic is only one of the elements required to achieve interoperability.Since data and services are hosted by devices (IED)a proper device model is needed along with compatible,domain specific services(see IEC 61850-7-2). The compatible logical node name and data name definitions found in this part and the associated semantic are fixed.The syntax of the type definitions of all data classes are abstract definitions provided in part IEC 61850-7-2 and-7-3 of this standard.Not all features of logical nodes are listed in part IEC 61850-7-4 e.g.data sets and logs are covered in part 1EC61850-7-2.

Draft 61850-7-4  IEC: 2002 – 9 – 57/WG10-12(61850-7-4)R3.0/FDIS Version 3.0: 22. August 2002 INTRODUCTION This document is part of a set of specifications. The complete set of specifications defines a layered substation communication architecture. This architecture has been chosen to provide abstract definitions of classes and services such that the specifications are independent of specific protocol stacks, implementations, and operating systems. The mapping of these abstract classes and services to communication stacks is outside the scope of part IEC 61850-7-x and may be found in part IEC 61850-8-x and -9-x. IEC 61850-7-1 gives an overview of this communication architecture. The part IEC 61850-7-3 defines common attribute types and common data classes related to substation applications. The attributes of the common data classes may be accessed using services defined in IEC 61850-7-2. These common data classes are used in part IEC 61850-7-4 to define the compatible data classes. To reach interoperability all data to be exchanged need a strong definition with regard to syntax and semantic. The semantic of the data is mainly provided by names assigned to logical nodes and data they contain as defined in the part IEC 61850-7-4. It should be noted that data with full semantic is only one of the elements required to achieve interoperability. Since data and services are hosted by devices (IED) a proper device model is needed along with compatible, domain specific services (see IEC 61850-7-2). The compatible logical node name and data name definitions found in this part and the associated semantic are fixed. The syntax of the type definitions of all data classes are abstract definitions provided in part IEC 61850-7-2 and -7-3 of this standard. Not all features of logical nodes are listed in part IEC 61850-7-4 e.g. data sets and logs are covered in part IEC 61850-7-2

The Logical Node Names and Data Names defined in this document are part of the class model introduced in IEC 61850-7-1 and defined in IEC 61850-7-2.The names defined in this document are used to build the hierarchical object references applied for communicating with IEDs in substations and on distribution feeders.The naming conventions of IEC 61850-7-2 are applied in IEC 61850-7-4. To avoid private,incompatible extension rules this part IEC 61850-7-4 specifies normative naming rules for multiple instances and private extensions of Logical Node (LN)Classes and Data Names. In the normative Annex A all rules with examples are given for: multiple instances of logical node classes by use of a LN instance identification (ID) multiple instances of data by use of a data instance ID selecting missing data out of the complete data name set creating new logical node classes and data names In the informative Annex B examples are given for: the use of Logical Nodes in complex situations like line protection schemes multiple instances of Logical Nodes with different levels of functionality This part does not provide tutorial material.It is recommended that parts IEC 61850-5 and IEC 61850-7-1 be read first,in conjunction with part IEC 61850-7-3,and-7-2.This part does not discuss implementation issues. This standard is applicable to describe device models and functions of substation and feeder equipment.The concepts defined in this standard may also be applied to describe device models and functions for: substation to substation information exchange substation to control centre information exchange. power plant to control centre information exchange. information exchange for distributed generation, information exchange for distributed automation,or information exchange for metering.
