Industrial communication networks - Profiles - Part 3-13: Functional safety fieldbuses - Additional specifications for CPF 13 (IEC 61784-3-13:2021)

IEC 61784-3-13:2021 specifies a safety communication layer (services and protocol) based on CPF 13 of IEC 61784 2 and IEC 61158 Type 13. It identifies the principles for functional safety communications defined in IEC 61784 3 that are relevant for this safety communication layer. This safety communication layer is intended for implementation in safety devices only.
NOTE 1 It does not cover electrical safety and intrinsic safety aspects. Electrical safety relates to hazards such as electrical shock. Intrinsic safety relates to hazards associated with potentially explosive atmospheres. This document defines mechanisms for the transmission of safety-relevant messages among participants within a distributed network using fieldbus technology in accordance with the requirements of IEC 61508 (all parts) for functional safety. These mechanisms may be used in various industrial applications such as process control, manufacturing automation and machinery. This document provides guidelines for both developers and assessors of compliant devices and systems.

L'IEC 61784-3-13:2021 spécifie une couche de communication de sécurité (services et protocole) qui repose sur la CPF 13 de l'IEC 61784 2 et le type 13 de l'IEC 61158. Elle identifie les principes applicables aux communications de sécurité fonctionnelle définies dans l'IEC 61784 3, qui correspondent à cette couche de communication de sécurité. Cette couche de communication de sécurité est destinée à être mise en œuvre uniquement sur les appareils de sécurité.
NOTE 1 Elle ne couvre pas les aspects relatifs à la sécurité électrique et à la sécurité intrinsèque. La sécurité électrique concerne les dangers tels que les chocs électriques. La sécurité intrinsèque concerne les dangers associés aux atmosphères explosibles. Le présent document définit les mécanismes de transmission des messages relatifs à la sécurité entre les participants d'un réseau réparti, en utilisant la technologie de bus de terrain conformément aux exigences de la série IEC 61508 (toutes les parties) concernant la sécurité fonctionnelle. Ces mécanismes peuvent être utilisés dans différentes applications industrielles, par exemple la commande de processus, l'usinage automatique et les machines. Le présent document fournit des lignes directrices aux développeurs, ainsi qu'aux évaluateurs d'appareils et de systèmes conformes.
