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.
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 61784-2:2019 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 fourth edition cancels and replaces the third edition published in 2014 and constitutes a technical revision. The main changes are: • update of reference from ISO/IEC 8802-3 to ISO/IEC/IEEE 8802-3; • update of the dated references to the IEC 61158 series, to IEC 61784 1, to the IEC 61784-5 series and to IEC 61918 throughout the document; • update of selection tables for CPF 2, CPF 3, CPF 4, CPF 8 and CPF 17; • CPF3: update of the requirements for all conformance classes; • CPF3: updated timing requirements for IO devices; • CPF3: refining the added application classes; • addition of a new Communication Profile Family – CPF 20 in Clause 21; • addition of a new Communication Profile Family – CPF 21 in Clause 22
