Industrial communication networks - Profiles - Part 3-8: Functional safety fieldbuses - Additional specifications for CPF 8 (IEC 61784-3-8:2016)

IEC 61784-3-8:2016 specifies a safety communication layer (services and protocol) based on CPF 8 of IEC 61784-1, IEC 61784-2 and IEC 61158 Type 18 and Type 23. 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 second edition cancels and replaces the first edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- Added FSCP 8/2;
- Added FSCP 8/2 Clause 12;
- Added content for FSCP 8/2 to Clauses 1 to 3 (scope, references, terms);
- Moved previous FSCP 8/1 to Clause 11 (demoting all old heading levels by one);
- Restructured old Clauses 4 to 10 to point to appropriate subclauses as appropriate.

L'IEC 61784-3-8:2016 spécifie une couche de communication de sécurité (services et protocole) reposant sur CPF 8 de l'IEC 61784-1, de l'IEC 61784-2 et de l'IEC 61158 Type 18 et Type 23. Elle identifie les principes en matière de communications de sécurité fonctionnelle définies dans l'IEC 61784-3 pertinents pour 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 deuxième édition annule et remplace la première édition, parue en 2010. Cette édition constitue une révision technique. Les modifications techniques majeures par rapport à l'édition précédente sont énumérées ci-dessous:
- FSCP 8/2 ajouté;
- FSCP 8/2, Article 12 ajouté;
- Contenu relatif à FSCP 8/2 ajouté aux Articles 1 à 3 (domaine d'application, références, termes);
- FSCP 8/1 précédent déplacé vers l'Article 11 (rétrogradant tous les anciens en-têtes d'un niveau);
- Anciens Articles 4 à 10 restructurés pour pointer vers les paragraphes appropriés, selon le cas.

Industrijska komunikacijska omrežja - Profili - 3-8. del: Funkcijska varnost procesnih vodil - Dodatne specifikacije za CPF 8 (IEC 61784-3-8:2016)

Standard IEC 61784-3-8:2016 določa varnostno komunikacijsko plast (storitve in protokoli), ki temelji na CPF 8 standardov IEC 61784-1, IEC 61784-2 in IEC 61158, tip 18 in tip 23. 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. Druga izdaja razveljavlja in nadomešča prvo izdajo, objavljeno leta 2010. Ta izdaja je tehnično popravljena izdaja. Ta izdaja vključuje naslednje znatne tehnične spremembe glede na prejšnjo izdajo:
– dodan FSCP 8/2;
– dodan FSCP 8/2, točka 12;
– dodana vsebina za FSCP 8/2 v točkah 1–3 (področje uporabe, reference, definicije);
– premik predhodnega FSCP 8/1 v točko 11 (znižanje vseh ravni naslova za eno raven);
– preoblikovane stare točke 4–10, da se po potrebi opozori na ustrezne podtočke.
