标准范围

IEC 61158-5-26:2019（E）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（参见ISO/IEC 7498-1）和OSI应用层结构（参见ISO/IEC 9545）。FAL服务和协议由应用程序流程中包含的FAL应用实体（AE）提供。FAL AE由一组面向对象的应用服务元素（ASE）和管理AE的层管理实体（LME）组成。ASE提供在一组相关应用进程对象(APO)类上操作的通信服务。其中一个FAL ASE是管理ASE，其为FAL类的实例的管理提供一组公共服务。

IEC 61158-5-26:2019(E) specifies the structure and services of the IEC fieldbus Application Layer, in conformance with the OSI Basic Reference Model (see ISO/IEC 7498-1) and the OSI Application Layer Structure (see ISO/IEC 9545).FAL services and protocols are provided by FAL application-entities (AE) contained within the application processes. The FAL AE is composed of a set of object-oriented Application Service Elements (ASEs) and a Layer Management Entity (LME) that manages the AE. The ASEs provide communication services that operate on a set of related application process object (APO) classes. One of the FAL ASEs is a management ASE that provides a common set of services for the management of the instances of FAL classes.
