工业通讯网络.配置文件.第2部分:基于ISO/IEC 8802-3标准的实时网络用附加数据总线配置文件

[中文适用范围]： IEC 61784 的这一部分规定了 ?支持实时以太网（RTE）要求分类方案的性能指标； ？基于 ISO/IEC 8802-3、IEC 61158 系列和 IEC 61784-1 的配置文件和相关网络组件； ？ RTE 解决方案能够与基于 ISO/IEC 8802-3 的应用程序并行运行。这些通信配置文件称为实时以太网通信配置文件。 [外文原描述]： 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.
