Specifies communication aspects of a programmable controller.
Speicherprogrammierbare Steuerungen - Teil 5: Kommunikation
Contrôleurs programmables - Partie 5: Communications
La CEI 61131-5:2000 spécifie les aspects des automates programmables (AP) relatifs à la communication. Elle spécifie, du point de vue d'un AP, la manière dont chaque périphérique peut communiquer avec un AP en tant que serveur et la manière dont l'AP peut communiquer avec chaque périphérique. Elle spécifie, en particulier, le comportement de l'AP lorsqu'il fournit des services pour le compte d'autres périphériques et les services que le programme application de l'AP peut demander aux autres périphériques. La présente version bilingue (2012-08) correspond à la version anglaise monolingue publiée en 2000-11. Cette publication doit être lue conjointement avec la série CEI 61131.

This European Standard was approved by CENELEC on 2001-01-01. 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, Czech Republic,
Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway,
Portugal, Spain, Sweden, Switzerland and United Kingdom.

Foreword
The text of document 65B/411/FDIS, future edition 1 of IEC 61131-5, prepared by SC 65B, Devices,
of IEC TC 65, Industrial-process measurement and control, was submitted to the IEC-CENELEC
parallel vote and was approved by CENELEC as EN 61131-5 on 2001-01-01.
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) 2001-10-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2004-01-01
This part is to be read in conjunction with the other parts of EN 61131.
Annexes designated "normative" are part of the body of the standard.
In this standard, annexes A, B and ZA are normative.
Annex ZA has been added by CENELEC.
__________
Endorsement notice
The text of the International Standard IEC 61131-5:2000 was approved by CENELEC as a European
Standard without any modification.
