Foreword
The text of document 65C/601/FDIS, future edition 2 of IEC 61784-2, 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 61784-2 on 2010-09-01.
This European Standard supersedes EN 61784-2:2008.
The main changes with respect to EN 61784-2:2008 are listed below:
a) update of the dated references to the EN 61158 series, to EN 61784-1, to the EN 61784-3 series, to
the EN 61784-5 series and to EN 61918 throughout the document;
b) update of selection tables for CPF 2, CPF 3, CPF 11 and CPF 14;
c) addition of a new profile CP 11/2 in 12.3;
d) addition of a new profile CP 14/3 in subclause 15.5;
e) addition of a new Communication Profile Family - CPF 17;
– new subclause 3.3.12 (CPF 17 symbols);
– new Clause 18 for CPF 17 with one profile;
f) addition of a new Communication Profile Family - CPF 18;
– new subclause 3.3.13 (CPF 18 symbols);
– new Clause 19 for CPF 18 with one profile;
– specification changes for CPF3;
g) update of the requirements for all conformance classes;
h) added precise timing requirements for IP;
i) updated timing requirements for IO devices;
j) added precise timing requirements for PTCP;
k) increasing the amount of synchronized devices in line;

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
national standard or by endorsement (dop) 2011-06-01
