IEC 61784-2:2010 specifies performance indicators supporting classification schemes for Real-Time Ethernet (RTE) requirements; profiles and related network components based on ISO/IEC 8802-3, IEC 61158 series, and IEC 61784-1; RTE solutions that are able to run in parallel with ISO/IEC 8802-3-based applications. These communication profiles are called Real-Time Ethernet communication profiles. This second edition cancels and replaces the first edition published in 2007 and constitutes a technical revision. The main changes with respect to the previous edition are:- update of the dated references to the IEC 61158 series, to IEC 61784-1, to the IEC 61784-3 series, to the IEC 61784-5 series and to IEC 61918 throughout the document;- update of selection tables for CPF 2, CPF 3, CPF 11 and CPF 14;- addition of a new profile CP 11/2 in 12.3;- addition of a new profile CP 14/3 in subclause 15.5;- 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;- 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;- update of the requirements for all conformance classes;- added precise timing requirements for IP;- updated timing requirements for IO devices;- added precise timing requirements for PTCP;- increasing the amount of synchronized devices in line;- integrating the fast startup as additional feature.This bilingual version published in 2011-12, corresponds to the English version published in 2010-07.
IEC 61784-2:2014 specifies the performance indicators supporting classification schemes for Real-Time Ethernet (RTE) requirements; the profiles and related network components based on ISO/IEC 8802-3 or IEEE 802.3, IEC 61158 series, and IEC 61784-1 and the RTE solutions that are able to run in parallel with ISO/IEC 8802-3 or IEEE 802.3 based applications. These communication profiles are called Real-Time Ethernet communication profiles. This third edition cancels and replaces the second edition published in 2010 and constitutes a technical revision. The main changes are: - update of selection tables for CPF 3; - update of selection tables for CPF 11 and CPF 14; - addition of a new profile CP 11/3 in 12.4; - addition of a new profile CP 14/4 in 15.6; - addition of a new Communication Profile Family - CPF 8 in Clause 20.
