Industrial communication networks - Profiles - Part 3-1: Functional safety fieldbuses - Additional specifications for CPF 1
IEC 61784-3-1:2007 specifies a safety communication layer (services and protocol) based on CPF 1 of IEC 61784-1 and IEC 61158 Type 1 and 9. It identifies the principles for functional safety communications defined in IEC 61784-3 that are relevant for this safety communication layer. This bilingual version (2014-12) corresponds to the English version, published in 2007-12.
Réseaux de communication industriels - Profils - Partie 3-1: Bus de terrain à sécurité fonctionnelle - Spécifications complémentaires pour le CPF 1
L'IEC 61784-5-6:2007 définit une couche de communication relative à la sécurité (services et protocole) fondée sur la CPF 1 de la CEI 61784-1 et les types 1 et 9 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. La présente version bilingue (2014-12) correspond à la version anglaise monolingue publiée en 2007-12.
