Industrial communication networks - Profiles - Part 3-2: Functional safety fieldbuses - Additional specifications for CPF 2 (IEC 61784-3-2:2010)
This part of the IEC 61784-3 series specifies a safety communication layer (services and protocol) based on CPF 2 of IEC 61784-1, IEC 61784-2 and IEC 61158 Type 2. It identifies the principles for functional safety communications defined in IEC 61784-3 that are relevant for this safety communication layer. This part 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 series2 for functional safety. These mechanisms may be used in various industrial applications such as process control, manufacturing automation and machinery. This part provides guidelines for both developers and assessors of compliant devices and systems.

La CEI 61784-3-2:2010 spécifie une couche de communication relative à la sécurité (services et protocole) fondée sur la CPF 2 de la CEI 61784-1, la CEI 61784-2 et le Type 2 de la CEI 61158. Elle identifie les principes applicables aux communications de sécurité fonctionnelle définies dans la CEI 61784-3, et appropriés à cette couche de communication de sécurité. Elle 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 CEI 61508 concernant la sécurité fonctionnelle. Ces mécanismes peuvent être utilisés dans diverses applications industrielles, telles que la commande de processus, l'usinage automatique et les machines. Cette seconde édition annule et remplace la première édition publiée en 2007. Elle constitue une révision technique. Les principales modifications par rapport à l'édition précédente sont:
