BAS EN 61784-2:2012

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:<br /> - 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;<br /> - update of selection tables for CPF 2, CPF 3, CPF 11 and CPF 14;<br /> - addition of a new profile CP 11/2 in 12.3;<br /> - addition of a new profile CP 14/3 in subclause 15.5;<br /> - addition of a new Communication Profile Family - CPF 17;<br /> - new subclause 3.3.12 (CPF 17 symbols);<br /> - new Clause 18 for CPF 17 with one profile;<br /> - addition of a new Communication Profile Family - CPF 18;<br /> - new subclause 3.3.13 (CPF 18 symbols);<br /> - new Clause 19 for CPF 18 with one profile;<br /> - specification changes for CPF3;<br /> - update of the requirements for all conformance classes;<br /> - added precise timing requirements for IP;<br /> - updated timing requirements for IO devices;<br /> - added precise timing requirements for PTCP;<br /> - increasing the amount of synchronized devices in line;<br /> - integrating the fast startup as additional feature.<br /> This bilingual version published in 2011-12, corresponds to the English version published in 2010-07.
