标准范围
IEC 61158-5-19:20 19定义了在用户和现场总线参考模型的应用层之间的边界处向FAL用户提供的服务，以及在现场总线参考模型的应用层和系统管理之间的边界处的系统管理。本标准规定了IEC现场总线应用层的结构和服务，符合OSI基本参考模型（ISO/IEC 7498-1）和OSI应用层结构（ISO/IEC 9545）。第四版取消并取代了2014年出版的第三版，构成技术修订。与上一版相比，此版本包括以下重大技术变更:？改进热插拔和冗余功能；？改进相位切换和错误处理；编辑改进
IEC 61158-5-19:2019 defines the services provided to the FAL user at the boundary between the user and the application layer of the fieldbus reference model, and Systems Management at the boundary between the application layer and Systems Management of the fieldbus reference model. This standard specifies the structure and services of the IEC fieldbus application layer, in conformance with the OSI Basic Reference Model (ISO/IEC 7498-1) and the OSI application layer structure (ISO/IEC 9545). This fourth edition cancels and replaces the third edition published in 2014 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
？improving the hotplug and redundancy features;
？improving the phase switching and the error handling;？editorial improvements
