IEC/TS 62771-2012 pdf free.Information model covering the contents of IEC 81346-1 and IEC 81346-2, IEC 61175, IEC 61666 and IEC 81714-3.
This Technical Specification contains a formal reference information model of the concepts and methods established in lEG 81346-1, IEC 81346-2, IEC 61175, lEG 61666 and IEC 81714-3, which are its normative basis.
The information model is normative with respect to data exchange.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in lEG 81346-1. IEC 81346-2, lEG 61175, IEC 61666, and lEG 8174-3 apply.
The standards IEC 81346-1, IEC 81346-2, IEC 61175, IEC 61666 and lEG 81714-3 are interrelated, but the concepts used in these standards have so far only been dealt with separately in the different publications. The purpose of the present technical specification is to illustrate their relations by means of a common reference information model.
When data is transferred or exchanged, the exchange shall conform to this reference model. The model is conceptual and independent from any implementation method.
For the preparation of the information model, the EXPRESS modelling language, described in ISO 10303-11, has been used. The graphical form is presented using EXPRESS-G.
The information model is contained in Annex A.
0 provides an overview by means of a graphical representation of the structure and constraints of the application objects. The computer interpretable textual form is represented in A.3.
A.1 lists the entities and attributes of the information model and A.2 contains the detailed verbal descriptions of the entities and attributes.
The reference information model depicts the requirements set up, using where possible available subsets of application reference models of the ISO 10303 series.
The model is not intended to be complete within the framework of neither integrated resource models nor application reference models developed within the ISO 10303 series. It is complete with respect to the requirements established within this publication.
NOTE 1 For an introduction to EXPRESS-G, see http://tc3.iec.ch/txt/xpress.pdl. NOTE 2 Annex A is available in the English language only.
Annex B contains a set of source definitions for Data Element Types (DETs) derived from the common reference information model.IEC/TS 62771 pdf free download.
