IEC Representation of process control engineering – Requests in P&I diagrams and data exchange between P&ID tools and PCE-CAE tools. In the domain of process automation there exist two upcoming standards for the modeling of plant data, namely ISO and IEC IEC Ed. “Representation of process control engineering – Requests in P&I diagrams and data exchange between P&ID tools and PCE-CAE tools”.

The structure and the fundamental characteristics of a plant are determined during the planning stage.
CAEX – Wikipedia
CAE-systems support the planning process and maintain the results within suitable data repositories. With a large number of different planners and work groups taking part, the planning process is typically very collaborative. Depending on the discipline, the planning phase or the assigned organizational unit, the respective planners use individual CAE-systems that are optimized for their working environment.
Continued efforts of the users to unify this tool landscape through standardizations have proven that this is only sensible and possible to a certain degree. The same can be said about efforts on the side of the manufactures to solve the overall task with an integrated proprietary system.
The reason for this is neither grounded in the variety of different procedure models or preferences of the participating groups nor in the diversity of the objects that are to be determined, but rather in the immense complexity of the application models and aspects. In the given context, the realization of a comprehensive and 6244 application model appears unlikely.

However, such a model is the prerequisite for a unified repository or a standardized exchange of planning data. This begs the question, how the repository and the standardized exchange of planning data can be organized without a standardized application model in the future.
A sufficient answer to this question is necessary in order to ensure a continuous DV technical information flow in the engineering process and across the entire life cycle of the plant. The presented meta model can be considered a starting point.
The 2nd edition of IEC 62424 is released
It appears to be suitable as both, a structuring aid for the data repository and as a basis for the open information exchange between different systems. The main focus of development, however, is the open exchange of information.
XML presents itself as a future-proof tool for the transmission of semantically structured data due to its wide distribution in the field. For this reason, the description of the meta model is realized in the form of an XML-scheme.
XML is an open standard which allows a formal description of restrictions and connections of the transferred data. XML files are structured documents that can be read and processed by any application. However, XML is only one description form of the model.
Independent from XML, the model itself can be described in other languages as well. Faculties and Institutions You Are Here: Navigation Academics Research The Chair. Other Resources Jobs open Institutions Association of Friends.
