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,
Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,
Sweden, Switzerland and the United Kingdom.

Foreword
The text of document 65C/476/FDIS, future edition 1 of IEC 61158-6-8, 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 61158-6-8 on 2008-02-01.
This and the other parts of the EN 61158-6 series supersede EN 61158-6:2004.
With respect to EN 61158-6:2004 the following changes were made:
– deletion of Type 6 fieldbus for lack of market relevance;
– addition of new fieldbus types;
– partition into multiple parts numbered 6-2, 6-3, …6-20.
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with the EN have to be withdrawn (dow) 2011-02-01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:
 DE 197 39 297 C2 [PxC] "Automatisierungssystem und Steuervorrichtung zur transparenten Kommunikation
zwischen verschiedenen Netzwerken."
 US 2002/0042845 A1 [PxC] "Automation System and connecting Apparatus for the Transparent Communication
between two Networks."
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
 Intellectual Property Licenses & Standards
 Flachsmarktstr. 8
 D-32825 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.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates close
