Industrial communication networks - Profiles - Part 3: Functional safety fieldbuses - General rules and profile definitions
It explains some common principles than can be used in the transmission of safety-relevant messages among participants within a distributed network using fieldbus technology in accordance with the requirements of IEC 61508 series for functional safety. These principles can be used in various industrial applications such as process control, manufacturing automation and machinery. It specifies several functional safety communication profiles based on the communication profiles and protocol layers of the fieldbus technologies in IEC 61784 1, IEC 61784 2 and the IEC 61158 series.

Foreword
The text of document 65C/470/FDIS, future edition 1 of IEC 61784-3, 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 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with the EN have to be withdrawn (dow) 2011-05-01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 functional safety
communication profiles for families 1, 2, 3 and 6 given in EN 61784-3-1, EN 61784-3-2, EN 61784-3-3
and EN 61784-3-6.
The IEC and CENELEC take no position concerning the evidence, validity and scope of these patents
right.
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
respect, the statements of the holders of these patent rights are registered with the IEC.
NOTE Patent details and corresponding contact information are provided in EN 61784-3-1, EN 61784-3-2, EN 61784-3-3 and
