Industrial communication networks - Fieldbus specifications -- Part 4-8: Data-link layer protocol specification - Type 8 elements

The data-link layer provides basic time-critical messaging communications between devices in an automation environment. This protocol provides a highly-optimized means of interchanging fixed-length input/output data and variable-length segmented messages between a single master device and a set of slave devices interconnected in a loop (ring) topology. The exchange of input/output data is totally synchronous by configuration, and is unaffected by the messaging traffic. Devices are addressed implicitly by their position on the loop. The determination of the number, identity and characteristics of each device can be configured, or can be detected automatically at start-up.

Réseaux de communication industriels - Spécifications des bus de terrain - Partie 4-8: Spécification des protocoles des couches de liaison de données - Eléments de type 8

La CEI 61158-4-8:2007 fournit un moyen fortement optimisé d'échanger des données d'entrée/de sortie de longueur fixe ainsi que des messages segmentés de longueur variable entre un seul appareil maître et un ensemble d'appareils esclaves interconnectés selon une topologie en boucle (anneau). L'échange de données d'entrée/de sortie est totalement synchrone du point de vue de la configuration, et n'est pas affecté par le trafic de messagerie. Les appareils sont adressés implicitement par leur position sur la boucle. La détermination du numéro, de l'identité et des caractéristiques de chaque appareil peut être configurée, ou peut être détectée automatiquement au démarrage. Cette première édition et ses parties d'accompagnement de la sous-série CEI 61158-4 annulent et remplacent la CEI 61158-4:2003. Elle constitue une révision éditoriale et inclut les modifications significatives suivantes:
- suppression du précédent bus de terrain de Type 6 et du réceptacle ("placeholder") pour une couche liaison de données de bus de terrain de Type 5, en raison du manque de pertinence commerciale;
- ajout de nouveaux types de bus de terrain;
- division de la présente partie en plusieurs parties. La présente version bilingue correspond à la version anglaise monolingue publiée en 2007-12.

This European Standard was approved by CENELEC on 2008-02-01. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Cyprus, the
Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,

Foreword
The text of document 65C/474/FDIS, future edition 1 of IEC 61158-4-8, prepared by SC 65C, Industrial
networks, of IEC TC 65, Industrial-process measurement, control and automation, was submitted to the
IEC-CENELEC parallel vote and was approved by CENELEC as EN 61158-4-8 on 2008-02-01.
This and the other parts of the EN 61158-4 series supersede EN 61158-4:2004.
With respect to EN 61158-4:2004 the following changes were made:
– deletion of Type 6 fieldbus, and the placeholder for a Type 5 fieldbus data-link layer, for lack of market
relevance;
– addition of new fieldbus types;
– partition into multiple parts numbered 4-1, 4-2, …, 4-19.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2008-11-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2011-02-01
NOTE  Use of some of the associated protocol types is restricted by their intellectual-property-right holders. In all cases, the
commitment to limited release of intellectual-property-rights made by the holders of those rights permits a particular data-link layer
protocol type to be used with physical layer and application layer protocols in type combinations as specified explicitly in the
EN 61784 series. Use of the various protocol types in other combinations may require permission from their respective
intellectual-property-right holders.
IEC and CENELEC draw attention to the fact that it is claimed that compliance with this standard may involve the use of patents as
follows, where the [xx] notation indicates the holder of the patent right:
Type 8 and possibly other types:
 DE 41 00 629 C1 [PxC] Steuer- und Datenübertragungsanlage
IEC and CENELEC take no position concerning the evidence, validity and scope of these patent rights.
The holders of these patent rights have assured IEC that they are willing to negotiate licences under reasonable and non-
discriminatory terms and conditions with applicants throughout the world. In this respect, the statement of the holders of these
patent rights are registered with IEC. Information may be obtained from:
[PxC]: Phoenix Contact GmbH & Co. KG
 Referat Patente / Patent Department
 Postfach 1341
 D-32819 Blomberg
 Germany
Attention is drawn to the possibility that some of the elements of this standard may be the subject of patent rights other than those
identified above. IEC and CENELEC shall not be held responsible for identifying any or all such patent rights.
Annex ZA has been added by CENELEC.
