标准范围

IEC 61784-2:20 19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或IEEE 802.3、IEC 61158系列和IEC 61784-1的配置文件和相关网络组件，以及能够与基于ISO/IEC 8802-3或IEEE 802.3的应用程序并行运行的RTE解决方案。这些通信简档被称为实时以太网通信简档。第四版取消并取代了2014年出版的第三版，构成技术修订。主要变化有:？将参考文献从ISO/IEC 8802-3更新为ISO/IEC/IEEE 8802-3；？更新整个文件中对IEC 61158系列、IEC 61784 1、IEC 61784-5系列和IEC 61918的引用日期；？更新CPF 2、CPF 3、CPF 4、CPF 8和CPF 17的选择表；？CPF3:更新所有符合性类别的要求；？CPF3:更新了IO设备的时序要求；？CPF3:细化添加的应用类；？在条款21中添加新的通信简档族-CPF 20；？在第22条中添加新的通信配置文件系列-CPF 21

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
