Want To Know What The IEC 61850 Tissue Process Is All About?

Please click HERE to find a good description of the IEC 61850 Tissue process as defined by IEC TC 57 - written by Christoph Brunner.

The tissue database was designed by my son Michael Schwarz and myself in 2004. At that time we exchanged tissues, questions, discussions, results ... by email ... and somebody took note of the discussion and wrote something into the tissues word document ... huch ... which was the latest version ...? Quite confusing.

NettedAutomation wanted to offer a free of charge service to the community that allows everybody to post any new tissue on a single entry point ... and to get a single, always up-to-date list ... Since then we have improved the tissue database according to the experience made by the global community.

Nowadays the tissue database is an integral part of the IEC 61850 and related standard series like IEC 61400-25 ... all new editions of any part of these series has a list of tissues taken into account in the new edition, e.g., in the name space document of part 7-4:

IEC 61850-7-2 2007A3 NSD light code component, see the IEC 61850-7-2:2010 for full legal notices:

Click HERE to download that name space document. That document lists the tissues taken into account since version 2007/A:

    

Click HERE for tissue 1652.

So, the tissue process is a core service offered by IEC to the global community! In case you have a comment on the tissue database, let me know.

In case you would be interested in such a tissue database for your standards or other projects, let me know please ... we could provide you an offer.

How Many and Which Information Models are defined in IEC 61850?

I guess you have heard that IEC 61850 defines a lot of Information Models. Yes, You are right.

The models are managed exclusively by the corresponding working groups with the Enterprise Architect UML Tool (the UML data base is for internal use only). The model version:

UML model of 61850 (wg10built6-wg18built3-wg17built5-jwg25built2-tc17built1-tc38built1.eap)

comprises the following number of Logical Node Classes, Data Objects (Attributes), Enumerations and Abbreviations:



An excerpt from the UML modes looks like this:



The UML Model is the single source data base that is used for the extensions and maintenance of the model, as well as the generation of Word or PDF documents ... The PDF documents are sold by IEC and other organizations.

You may complain that the standards are not for free ... hmm ... BUT look: You can download the various Code Components for free.

Click HERE for the Code Component for IEC_61850-7-4.NSD.2007A2.light.zip (IEC 61850-7-4 2007A2 NSD light, see the IEC 61850-7-4:2010 for full legal notices). The full version has additionally the semantic descriptions of the models.

Example of Enumeration:


Example of excerpt of LN Class MMU:



Click HERE to see the list of all Code Components as per today ... more to come soon.

To my understanding you can model many required information generated and consumed by a huge number of applications in almost all application domains of automation in the electrical system and beyond.

As the above example of MMXU shows, you can use this LN Class wherever you have 3 phase AC system!! In a building heating system for the electrical values of a compressor or a fan or a pump or ... the blue sky is the limit for the applications.

Click HERE to learn about crucial details discussing the LN Class MMXU and how it can be applied ... you may have never expected this comprehensiveness of the MMXU.

Note that the 3 phase system was first (more than 100 years ago) - then we have put a facade in front of the measurement function which exposes the measurements as data objects of the class MMXU. The application has driven the class - not vice versa.

The current edition 2.1 models defined in IEC 61850-7-3 and 7-3 are listed in the contents tables of the preview documents. The following Preview documents (free access) for models of the edition 2.1 consolidated versions are available:

Preview IEC 61850-7-3 Edition 2.1
Preview IEC 61850-7-4 Edition 2.1

Example of 7-4 from the preview:

IEC Offers Code Components for IEC 61850 and other standards

One of the most crucial benefits of IEC 61850 information models is the availability of code components - the possibility to get a computer processable document that contains the formal definition of a model, e.g., the measurements of a three phase system.

The following document has just been published:

Handling of Code Components in IEC Standards
Including Copyright Licensing

Handling of Code Components v8.0 2019-08-29

This document sets out the process and rules to be used by IEC groups (TCs, SCs, PCs, WGs, SyCs, …) and experts in charge of editing IEC documents to ensure a proper handling of copyright licensing of code components included in IEC deliverables. It also defines the technical and process requirements to consider to optionally offer a free access to certain code component(s) through the IEC web site. At the current time this document only applies to IEC TC57

WOW -- IEC 61850 Models Publically Available for Download

After long time, IEC has accepted to provide free online access to the IEC 61850 Models!!

Congratulation!

Excerpt from 57/2023/INF (2018-07-13):

"With IEC 61850-7-7, a machine processable format for the distribution of IEC 61850 data models has been defined. Based on that, in the future, all IEC 61850 models will be as well available in this format as namespace files (NSD files).
The namespace files are code components, that are intended to be directly processed by a computer. The purchase of the associated IEC standard carries a copyright license for the purchaser to sell software containing Code Components from this standard to end users either directly or via distributors, subject to IEC software licensing conditions, which can be found at: http://www.iec.ch/CCv1. ..."
