scope:

General

This part of IEC 61850, which is a Technical Specification, specifies a way to model the code components of IEC 61850 data model (e.g., the tables describing logical nodes, common data classes, structured data attributes, and enumerations) in an XML format that can be imported and interpreted by tools. The following main use cases are supported:

• Generation of SCL data type templates for system specification or ICD files.

• Validation of SCL data type templates.

• Definition of private extensions by following the rules of the standard.

• Adapting rapidly the whole engineering chain as soon as a new version of IEC 61850 data model (an addendum, a corrigenda or a Tissue) affects the content of the standard.

• Provide tool-neutral textual help to users of tools on the data model contents.

• Supporting multi-language publication, i.e., enabling the expression of the data model in different languages, through a machine processable format.

The purpose of this document is limited to the publication of the XML format which should support the data model part of any IEC 61850-related standard. The publication of code components themselves will be part of the related IEC 61850 part, and IEC 61850-1-2 will indicate the requirements to produce NSD files for other purpose than core datamodel.

Published versions

This technical specification defines one namespace:

- A NameSpace Definition (NSD)

Code Component distribution

General

Each Code Component is a ZIP package containing at least the electronic representation of the Code Component itself and a file describing the content of the package (IECManifest.xml).

The life cycle of a code component is not restricted to the life cycle of the related publication. The publication life cycle goes through two stages, Version (corresponding to an edition) and Revision (corresponding to an amendment). A third publication stage (Release) allows publication of Code Component in case of urgent fixes of InterOp Tissues, thus without need to publish an amendment.

Consequently, new release(s) of the Code Component may be released, which supersede(s) the previous release, and will be distributed through the IEC TC 57 web site:

The latest version/release of the document will be found by selecting the file for the code component with the highest value for VersionStateInfo, e.g. IEC TS 61850-7-7.NSD.{VersionStateInfo}.full.zip.

XML schema namespace code component

The NSD code component namespace is an XML schema file. It will be available in a full version.

The full version is freely accessible on the IEC website for download at:

but the usage remains under the licensing conditions.

In case of any differences between the downloadable code and the IEC pdf published content, the downloadable code(s) is(are) the valid one; it may be subject to updates. See history files.
