Industrial communication networks - Profiles - Part 3: Functional safety fieldbuses - General rules and profile definitions
IEC 61784-3:2010(E) series explains some common principles than can be used in the transmission of safety-relevant messages among participants within a distributed network using fieldbus technology in accordance with the requirements of IEC 61508 series for functional safety. These principles can be used in various industrial applications such as process control, manufacturing automation and machinery. This second edition cancels and replaces the first edition published in 2007. This edition constitutes a technical revision. The main changes with respect to the previous edition are: - clarifications and additional explanations for requirements, updated references; - updates of definitions and requirements in relation with the new edition of IEC 61508; - addition of a new informative Annex D providing an assessment guideline; - addition of new parts for CPF 8, CPF 12, CPF 13, CPF 14; - in CPF parts, addition of an annex to provide information about test laboratories for testing and validating conformance of FSCP products.

Réseaux de communication industriels - Partie 3: Bus de terrain à sécurité fonctionnelle - Règles générales et définitions des profils
La CEI 61784-3:2010 définit des principes communs pouvant être appliqués pour la transmission des messages propres 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 principes 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 parue en 2007 et constitue une révision technique. Les principales modifications par rapport à l'édition précédente sont: - clarifications et explications complémentaires des exigences, références actualisées; - actualisations des définitions et exigences par rapport à la nouvelle édition de la CEI 61508; - ajout d'une nouvelle Annexe D informative fournissant une ligne directrice relative à l'évaluation; - actualisations des parties pour les CPF 1, CPF 2, CPF 3, CPF 6 (détails fournis dans les parties); - ajout de nouvelles parties pour les CPF 8, CPF 12, CPF 13, CPF 14; - dans les parties CPF, ajout d'une annexe afin de fournir des informations concernant les laboratoires d'essais, en vue d'une vérification par des essais et d'une validation de la conformité des produits FSCP. La présente version bilingue, correspond à la version anglaise monolingue publié en 2010-07.
Industrijska komunikacijska omrežja - Profili - 3. del: Funkcijska varnost procesnih vodil (IEC 61784-3:2010)
Ta del serije IEC 61784-3 razlaga nekatera skupna načela, ki se jih lahko uporabi pri prenosu za varnost pomembnih sporočil med udeleženci, v okviru porazdeljenega omrežja z uporabo tehnologije procesnih vodil v skladu z zahtevami IEC 61508 serije 1 za funkcijsko varnost. Ta načela se lahko uporabljajo pri različnih industrijskih uporabah, kot so procesni nadzor, proizvodnja avtomatizacija in stroji. Ta del 2 in deli IEC 61784-3-x določajo več komunikacijskih profilov za funkcijsko varnost, osnovanih na komunikacijskih profilih, ter protokolne plasti procesnih vodil v serijah IEC 61784-1, IEC 61784-2 in IEC 61158. OPOMBA 1: Drugi z varnostjo povezani komunikacijski sistemi, ki izpolnjujejo zahteva serije IEC 61508, so lahko prisotni, ki niso vključeni v ta standard. OPOMBA 2: Ne zajema električne varnosti in pripadajočih varnostnih vidikov. Električna varnost je povezana z nevarnostmi kot električni šok. Notranja varnost se nanaša na nevarnosti, ki so povezane s potencialno eksplozivnimi atmosferami. Vsi sistemi so izpostavljeni nepooblaščenemu dostopu na neki točki svojega življenjskega cikla. Treba je preučiti dodatne ukrepe pri kateri koli z varnostjo povezani uporabi za varovanje sistemov procesnih vodil pred nepooblaščenim dostopom Serije IEC 62443 bodo naslovile številna izmed teh vprašanja; odnos s serijami IEC 62443 je podrobno opisan v namenski podklavzuli tega dela. OPOMBA 3: Dodatne zahteve za varnost, značilne za profile, so lahko opredeljene tudi v IEC 61784-43 [10]. OPOMBA 4: Izvedba funkcijske varnosti komunikacijskega profila v skladu s tem delom v napravi ne zadostuje temu, da bi ustrezala varnostni napravi, kot je opredeljena v serijah 61508. OPOMBA 5: Izhajajoča SIL zahteva sistema je odvisna od izvedbe izbrane funkcijske varnosti komunikacijskega profila znotraj sistema.
