工业网络.配置文件.第2-12部分:基于ISO/IEC/IEEE 8802-3-CPF 12的附加实时现场总线配置文件

[中文适用范围]： 本标准规定了基于ISO/IEC/IEEE 8802-3的附加实时现场总线配置文件，适用于工业网络中的实时通信需求。该标准涵盖了物理层、数据链路层和应用层的选择，并提供了性能指标的评估方法。 [外文原描述]： IEC 61784-2-12:2023 defines Communication Profile Family 12 (CPF 12). CPF 12 specifies a set of Real-Time Ethernet (RTE) communication profiles (CPs) and related network components based on the IEC 61158 series (Type 12), ISO/IEC/IEEE 8802-3 and other standards. For each RTE communication profile, this document also specifies the relevant RTE performance indicators and the dependencies between these RTE performance indicators. NOTE 1 All CPs are based on standards or draft standards or International Standards published by the IEC or on standards or International Standards established by other standards bodies or open standards processes. NOTE 2 The RTE communication profiles use ISO/IEC/IEEE 8802-3 communication networks and its related network components and in some cases amend those standards to obtain RTE features.
