EN 61784-3-2:2017

Industrial communication networks - Profiles - Part 3-2: Functional safety fieldbuses - Additional specifications for CPF 2

IEC 61784 3-2:2016 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 safety communication layer is intended for implementation in safety devices only. This third edition cancels and replaces the second edition published in 2010. This edition constitutes a technical revision. The main changes with respect to the previous edition are listed below (and highlighted in yellow in this document): - Added detailed requirements for use of FSCP 2/1 in conjunction with CP 16/3 (see 4.1, 6.4.3, 6.5.3, 8.2, 8.13, and miscellaneous references when referencing CPF 2 networks); - Defined object class section keywords for safety to EDS file definition in 8.10.2.1; - New sections on safety CRC overview in 7.1.2.1 and Rollover counts for EF format in 7.4; - Corrections to PFH calculations in 9.5.2; - Change from MACID to NodeID as general reference to network identifier.

IEC 61784 3-2:2016 spécifie une couche de communication relative à la sécurité (services et protocole) fondée sur la CPF 2 de l'IEC 61784-1, l'IEC 61784-2 et le Type 2 de l'IEC 61158. Elle identifie les principes applicables aux communications de sécurité fonctionnelle définies dans l'IEC 61784-3, et appropriés à cette couche de communication de sécurité. Cette couche de communication de sécurité est destinée à être mise en oeuvre uniquement sur les appareils de sécurité. Cette troisième édition annule et remplace la deuxième édition parue en 2010. Cette édition constitue une révision technique. Les modifications majeures par rapport à l'édition précédente sont énumérées ci-dessous (et surlignées en jaune dans le présent document): - Ajout d'exigences détaillées pour l'utilisation de FSCP 2/1 en liaison avec CP 16/3 (voir 4.1, 6.4.3, 6.5.3, 8.2, 8.13, et diverses références lors du référencement des réseaux CPF 2); - Définition des mots-clés de la section de classe d'objet pour la sécurité donnée dans la définition du fichier EDS en 8.10.2.1; - De nouvelles sections sur la présentation générale du CRC de sécurité en 7.1.2.1 et les comptages de remplacement pour le format EF en 7.4; - Corrections apportées aux calculs de la PFH en 9.5.2; - Changement de MACID en NodeID à titre de référence générale à l'identifiant de réseau.

Industrijska komunikacijska omrežja - Profili - 3-2. del: Funkcijska varnost procesnih vodil - Dodatne specifikacije za CPF 2 (IEC 61784-3-2:2016)

Ta del skupine standardov IEC 61784-3 določa varnostno komunikacijsko plast (storitve in protokoli), ki temelji na CPF 2 standardov IEC 61784-1, IEC 61784-2 in IEC 61158, tip 2. Določa načela za komunikacijsko funkcionalno varnost, opredeljena v IEC 61784-3, ki so pomembna za to varnostno komunikacijsko plast. Ta varnostna komunikacijska plast je predvidena za uporabo v varnostnih napravah.
OPOMBA 1: Standard ne zajema električne varnosti in intrinzičnih varnostnih vidikov. Električna varnost se nanaša na nevarnosti, kot je električni udar. Intrinzična varnost se nanaša na nevarnosti, ki so povezane s potencialno eksplozivnimi atmosferami. Ta 1. del določa mehanizme za prenos, ki jih je mogoče uporabiti pri prenosu z vidika varnosti pomembnih sporočil med udeleženci v porazdeljenem omrežju z uporabo tehnologije procesnih vodil v skladu z zahtevami skupine 2 standardov IEC 61508 za funkcijsko varnost. TI mehanizmi se lahko uporabljajo pri različnih industrijskih uporabah, kot so procesni nadzor, proizvodna avtomatizacija in stroji.
Ta del podaja smernice za razvijalce in ocenjevalce združljivih naprav in sistemov.
OPOMBA 2: Posledična stopnja varnostne celovitosti (SIL) sistema je odvisna od izvedbe izbranega komunikacijskega profila za funkcionalno varnost znotraj tega sistema. Izvedba komunikacijskega profila za funkcionalno varnost v standardni napravi v skladu s tem delom ne zadostuje, da bi naprava izpolnjevala zahteve za varnostno napravo.
