IEC 61158-5-7:20 07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向系统管理提供的服务。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）和OSI应用层结构（ISO/IEC 9545）。IEC 61158-5子系列的第一版及其配套部分取消并取代IEC 61158-5:20 03。这一部分的这个版本构成了编辑修订。此版本的IEC 61158-5包括与上一版本相比的以下重大变化: -由于缺乏市场相关性，删除了以前的6型现场总线；-增加新型现场总线； -将第三版第5部分分成多个部分，编号为5-2、5-3、。这个双语版本（2014-12）对应于2007-12年出版的单语英文版。

IEC 61158-5-7:2007 defines the services provided to the FAL user at the boundary between the user and the Application Layer of the Fieldbus Reference Model, and SystemsManagement 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) and the OSI Application Layer Structure (ISO/IEC 9545). This first edition and its companion parts of the IEC 61158-5 subseries cancel and replace IEC 61158-5:2003. This edition of this part constitutes an editorial revision. This edition of IEC 61158-5 includes the following significant changes from the previous edition:
- deletion of the former Type 6 fieldbus for lack of market relevance;
- addition of new types of fieldbuses;
- partition of part 5 of the third edition into multiple parts numbered 5-2, 5-3,. This bilingual version (2014-12) corresponds to the monolingual English version, published in 2007-12.
