IEC 61784-2:2010(E) 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. It constitutes a technical revision. The main changes with respect to the previous edition are listed below: - 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.
