What is PD IEC/TS 62771 - Formal reference information model about?
PD IEC/TS 62771 is a technical specification that contains a formal reference information model of the concepts and methods established in IEC 81346-1, IEC 81346-2, IEC 61175, IEC 61666, and IEC 81714-3, which is its normative basis. The information model is normative with respect to data exchange.
PD IEC/TS 62771 addresses the reference information model and the data elements types definitions in annex A and annex B respectively.
Who is PD IEC/TS 62771 - Formal reference information model for?
PD IEC/TS 62771 on formal reference information model  is useful for:
- Data representation
- Software engineers
- Circuit diagrams
- Computer engineers
Why should you use PD IEC/TS 62771 - Formal reference information model?
The standards IEC 81346-1, IEC 81346-2, IEC 61175, IEC 61666 and IEC 81714-3 are interrelated, but the concepts used in these standards have so far only been dealt with separately in different publications. The purpose of PD IEC/TS 62771 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 of 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.
PD IEC/TS 62771 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 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. PD IEC/TS 62771 is complete with respect to the requirements established within this publication. Annex B contains a set of source definitions for Data Element Types (DETs) derived from the common reference information model.
