Standards Development

Scope

This document specifies the functional safety and reliability data model descriptions for low-voltage switchgear and controlgear to be used by engineering tools for the design of safety related control systems according to IEC 62061, IEC 61508-2 and ISO 13849-1, and for dependability analysis of electrotechnical systems.

This dictionary is used to facilit ate the exchange between computers of data characterizing low-voltage switchgear and controlgear.

Each property has an unambiguously defined meaning and naming, and where relevant, a defined value list, a defined format and a defined unit.

The data models described in this document are intended to complement the product catalogue data defined by IEC 62683-1 DB.

This document does not cover:

- exchange format such as defined in VDMA 66413,

- manufacturer specific features

Purpose

Engineering tools used for the design of safety control system of machinery and similar control systems needs functional safety and reliability data.

The purpose of this document is to:

• define the structure of the engineering data model classes and properties of low voltage switchgear
and controlgear suitable for use in functional safety applications based on VDMA 66413:2012 and other applications including dependability analysis.

• provide the method on how to provide and use these properties in typical applications.

The intended benefits of this standard are to:

• reduce the costs, time and efforts of mapping data for each customer request;

• optimize the workflow of information exchange with engineering tools;

• facilitate the selection of a product, especially regarding reliability and safety;

• give access to product data everywhere regardless of country, language and culture.
