IEC 62424 PDF

On a certain abstraction level, a plant consists of modules or components that are interconnected. CAEX allows storage of those modules or components by means of objects. Object oriented concepts such as encapsulation, classes, class libraries, instances, instance hierarchies, inheritance, relations, attributes and interfaces are explicitly supported. The original intention of developing CAEX was to remedy industry's lack of a common and established data exchange between process engineering tools and process control engineering tools.

Figure B. A complete IEC project implemented in an IEC environment can be transferred between different programming environments. This document specifies basic requirements for the installation of media for communication networks within and between the automation islands, of industrial sites. This standard covers balanced and optical fibre cabling. It also covers the cabling infrastructure for wireless media, but not the wireless media itself. Additional media are covered in the IEC series.

This document is a companion standard to the communication networks of the industrial automation islands and especially to the This report is to be read in conjunction with the first edition of the IEC series of standards only!

IEC specifies basic requirements for the installation of media for communication networks in industrial premises and within and between the automation islands, of industrial sites. This fourth edition cancels and replaces the third edition published in This edition constit IEC is a solution for data exchange focusing on the domain of automation engineering.

IEC specifies FB function blocks by using the result of a harmonization work as regards several elements. This includes general rules for the essential features to support control, whilst avoiding details which stop innovation as well as specialization for different industrial sectors.
