Description of BS EN 61850-8-1:2011+A1:2020 20201.1 General This part of IEC 61850 specifies a method of exchanging time-critical and non-time-critical data through local-area networks by mapping ACSI to MMS and ISO/IEC 8802-3 frames. MMS services and protocol are specified to operate over an OSI-A-Profile and TCP T-Profile. The use of MMS allows provisions for supporting both centralized and distributed architectures. This standard includes the exchange of real-time data indications, control operations, report notification. It specifies the mapping of the objects and services of the ACSI (Abstract Communication Service Interface, IEC 61850-7-2) to MMS (Manufacturing Message Specification, ISO 9506) and ISO/IEC 8802-3 frames. This standard also specifies the mapping of time-critical information exchanges to non-MMS protocol. The protocol semantics are defined in IEC 61850-7-2. It contains the protocol syntax, definition, mapping to ISO/IEC 8802-3 frame formats and any relevant procedures specific to the use of ISO/IEC 8802-3. This mapping of ACSI to MMS defines how the concepts, objects, and services of the ACSI are to be implemented using MMS concepts, objects, and services. This mapping allows interoperability across functions implemented by different manufacturers. This part of IEC 61850 defines a standardized method of using the ISO 9506 services to implement the exchange of data. For those ACSI services defined in IEC 61850-7-2 that are not mapped to MMS, this part defines additional protocols. It describes real utility devices with respect to their external visible data and behaviour using an object oriented approach. The objects are abstract in nature and may be used to a wide variety of applications. The use of this mapping goes far beyond the application in the utility communications. This part of IEC 61850 provides mappings for the services and objects specified within IEC 61850-7-2, IEC 61850-7-3, and IEC 61850-7-4. 1.2 Namespace name and version This new section is mandatory for any IEC 61850 namespace (as defined by IEC 61850-7-1). The parameters which identify this new release of this namespace are:
1.3 Code Component distribution The Code Component will be available in light and full version:
The link for downloading the light version of this code component is: http://www.iec.ch/tc57/supportdocuments/IEC 61850-8-1.NSD.2003A2.light.zip The Code Components for IEC 61850 data models (like the mapping of the control service parameter in this document) are available as the file format NSD defined by IEC 61850-7-7. The Code Component included in this IEC standard are potentially subject to maintenance works and user shall select the latest release in the repository located at: http://www.iec.ch/tc57/supportdocuments The latest version/release of the document will be found by selecting the file IEC 61850-8-1.NSD.{VersionStateInfo}.light.zip with the filled VersionStateInfo of the highest value. Each Code Component is a ZIP package containing the electronic representation of the Code Component itself, with a file describing the content of the package (IECManifest.xml). The IECManifest contains different sections giving information on:
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) allow publication of Code Component without need to publish an amendment. This is useful when InterOp Tissues need to be fixed. Then a new release of the Code Component will be released, which supersedes the previous release, and distributed through the IEC TC57 website.
