Industrial communication networks - Profiles - Part 3: Functional safety fieldbuses - General rules and profile definitions
IEC 61784-3:2016 is available as IEC 61784-3:2016 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 61784-3:2016 series explains some common principles that can be used in the transmission of safety-relevant messages among participants within a distributed network which use fieldbus technology in accordance with the requirements of IEC 61508 series for functional safety. These principles are based on the black channel approach. They can be used in various industrial applications such as process control, manufacturing automation and machinery. This part and the IEC 61784-3-x parts specify several functional safety communication profiles based on the communication profiles and protocol layers of the fieldbus technologies in IEC 61784-1, IEC 61784-2 and the IEC 61158 series. These functional safety communication profiles use the black channel approach, as defined in IEC 61508. These functional safety communication profiles are intended for implementation in safety devices exclusively. This third edition cancels and replaces the second edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - clarifications and additional explanations for requirements, updated references; - deletion of technical overviews of profiles (Clauses 6 to 13), and associated dedicated subclauses for terms, definitions, symbols and abbreviations; - addition of profiles for Communication Profile Families 8, 17 and 18 (Clauses 10, 14, 15); - clarifications of models in Annex A; - Annex B changed from informative to normative; - addition of a new informative Annex E describing models for explicit and implicit FSCP mechanisms; - addition of a new informative Annex F introducing an extended model for estimation of the total residual error rate; - updates in parts for CPF 1, CPF 2, CPF 3, CPF 8, CPF 13 (details provided in the parts); - addition of a new part for CPF 17.

Réseaux de communication industriels - Profils - Partie 3: Bus de terrain de sécurité fonctionnelle - Règles générales et définitions de profils
L'IEC 61784-3:2016 définit des principes communs qui peuvent être appliqués pour la transmission des messages relatifs à la sécurité entre les participants d'un réseau réparti, à l'aide de la technologie de bus de terrain conformément aux exigences de la série IEC 61508 sur la sécurité fonctionnelle. Ces principes peuvent s'appuyer sur le principe de canal noir. Ils peuvent être utilisés dans différentes applications industrielles, par exemple la commande de processus, l'usinage automatique et les machines. La présente partie et les parties IEC 61784-3-x spécifient plusieurs profils de communication de sécurité fonctionnelle basés sur les profils de communication et les couches de protocole des technologies des bus de terrain de l'IEC 61784-1, de l'IEC 61784-2 et de la série IEC 61158. Ces profils de communication de sécurité fonctionnelle utilisent le principe de canal noir, comme défini dans l'IEC 61508. Ces profils de communication de sécurité fonctionnelle sont destinés à être exclusivement mis en oeuvre dans des appareils de sécurité. Cette troisième édition annule et remplace la deuxième édition parue en 2010. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - clarifications et explications complémentaires des exigences, références actualisées; - suppression des présentations techniques de profils (Articles 6 à 13) et paragraphes dédiés associés à des termes, définitions, symboles et abréviations; - ajout de profils pour les familles de profils de communication 8, 17 et 18 (Articles 10, 14, 15); - clarifications des modèles de l'Annexe A; - modification de l'Annexe B informative qui devient normative; - ajout d'une nouvelle Annexe E informative pour décrire les modèles des mécanismes FSCP explicites et implicites; - ajout d'une nouvelle Annexe F informative qui introduit un modèle étendu pour l'estimation du taux total d'erreurs résiduelles; - actualisations des parties pour les CPF 1, CPF 2, CPF 3, CPF 8, CPF 13 (détails fournis dans les parties); - ajout d'une nouvelle partie pour CPF 17.
Industrijska komunikacijska omrežja - Profili - 3. del: Funkcionalno varna procesna vodila - Splošna pravila in definicije profilov (IEC 61784-3:2016)
Ta del skupine standardov IEC 61784-3 pojasnjuje nekatera splošna načela, 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 standardov IEC 61508 serije 1 za funkcijsko varnost. Ta načela temeljijo na pristopu »black channel«. Ta načela se lahko uporabljajo pri različnih industrijskih uporabah, kot so procesni nadzor, proizvodna avtomatizacija in stroji.
Ta 2. del in deli standarda IEC 61784-3-x določajo več komunikacijskih profilov za funkcionalno varnost, ki temeljijo na komunikacijskih profilih, in protokolne plasti procesnih vodil v skupinah standardov IEC 61784-1, IEC 61784-2 in IEC 61158. Ti komunikacijski profili za funkcionalno varnost uporabljajo pristop »black channel«, kot je opredeljeno v standardu IEC 61508. Ti komunikacijski profili za funkcionalno varnost so namenjeni izključno za uporabo v varnostnih napravah.
OPOMBA 1: Morda obstajajo drugi z varnostjo povezani komunikacijski sistemi, ki izpolnjujejo zahteve skupine standardov IEC 61508, ki niso vključeni v ta standard.
OPOMBA 2: Standard ne zajema električne varnosti in intrinzičnih varnostnih vidikov. Električna varnost je povezana z nevarnostmi, kot je električni udar. Intrinzična varnost se nanaša na nevarnosti, ki so povezane s potencialno eksplozivnimi atmosferami.
Vsi sistemi so na neki točki svojega življenjskega cikla izpostavljeni nepooblaščenemu dostopu. Treba je preučiti dodatne ukrepe pri vseh z varnostjo povezanih uporabah za zaščito sistemov procesnih vodil pred nepooblaščenim dostopom. Skupina standardov IEC 62443 bo obravnavala številna vprašanja; povezava s skupino standardov IEC 62443 je podrobno opisana v namenski podtočki tega dela.
OPOMBA 3: Dodatne varnostne zahteve, specifične za profile, so lahko opredeljene tudi v standardu IEC 61784-43.
OPOMBA 4: Izvedba komunikacijskega profila za funkcionalno varnost v napravi v skladu s tem delom ne zadostuje, da bi naprava izpolnjevala zahteve za varnostno napravo, kot je opredeljeno v skupini standardov IEC 61508.
OPOMBA 5: Posledična celovitost varnostnega sistema (SIL) je odvisna od izvedbe izbranega komunikacijskega profila za funkcionalno varnost znotraj tega sistema.
