IEC 61784-1:2010 defines a set of protocol specific communication profiles based primarily on the IEC 61158 series, to be used in the design of devices involved in communications in factory manufacturing and process control. Each profile selects specifications for the communications protocol stack at a device. It contains a minimal set of required services at the application layer and specification of options in intermediate layers defined through references. If no application layer is included, then a minimal set of required services at the Data-link layer is specified. The appropriate references to the protocol specific types are given in each communication profile family or associated profiles.

The main changes with respect to the previous edition are:- update of the dated references to the IEC 61158 series, to IEC 61784-2, to the IEC 61784-3 series, to the IEC 61784-5 series and to IEC 61918 throughout the document;- update of the titles of the referenced documents and references if needed;- update of selection tables for CPF 1, CPF 2, CPF 5 and CPF 8.This bilingual version published in 2011-12, corresponds to the English version published in 2010-07.
