This European Standard was approved by CENELEC on 2010-07-01. 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, Croatia, Cyprus,

Foreword
The text of document 65C/591A/FDIS, future edition 2 of IEC 61784-3-3, 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 61784-3-3 on 2010-07-01.
This European Standard supersedes EN 61784-3-3:2008.
The main technical changes with respect to EN 61784-3-3:2008 are listed below:
– updates in relation with changes in EN 61784-3;
– introduction of a secondary watchdog timer (F_WD_Time_2) to cover the use cases
'configuration-in-run', or 'maintenance of fault tolerance systems', or both (7.1.3, 7.2.3, 7.2.6, 8.1.1,
8.1.4, 8.1.6.2);
– missing GSDL definitions conveyed from other approved documents (8.3.2.1);
– missing CRC signature calculation for a GSD conveyed from other approved documents (8.3.3.3);
– constraints for the parameter value assignment of the primary watchdog timer 'F_WD_Time' (9.3.3);
– identification of the safety parameterization state of an F-Device or F-Module via field IM4 (signature)
within the I&M functions (9.6.2);
– updated documents in bibliography.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent
rights.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
(dop) 2011-04-01
national standard or by endorsement
– latest date by which the national standards conflicting
(dow) 2013-07-01
with the EN have to be withdrawn
Annex ZA has been added by CENELEC.
