Foreword
The text of document 65C/470/FDIS, future edition 1 of IEC 61784-3-2, 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 61784-3-2 on 2008-05-01.
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) 2009-02-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2011-05-01
The International Electrotechnical Commission (IEC) and CENELEC draw attention to the fact that it is
claimed that compliance with this document may involve the use of patents concerning the functional
safety communication profiles for family 2 as follows, where the [xx] notation indicates the holder of the
patent right:
US 6,631,476 [RA] Safety network for industrial controller providing redundant connections on single
media

US 6,891,850 [RA] Network independent safety protocol for industrial controller
US 6,915,444 [RA] Network independent safety protocol for industrial controller using data
manipulation techniques
The IEC and CENELEC take no position concerning the evidence, validity and scope of these patent
rights.
The holders of these patent rights have assured the IEC that they are willing to negotiate licences under
reasonable and non-discriminatory terms and conditions with applicants throughout the world. In this
