IEC 61158-3-2:20 23是为促进自动化系统组件互连而生产的系列之一。它与IEC 61158中描述的“三层”现场总线参考模型定义的集合中的其他标准相关？1. 在整个现场总线标准集合中，术语“服务”是指由OSI基本参考模型的一个层提供给紧接在其上的层的抽象能力。因此，本文档中定义的数据链路层服务是独立于管理和实现部门的概念架构服务。

IEC 61158-3-2:2023 is one of a series produced to facilitate the interconnection of automation system components. It is related to other standards in the set as defined by the "three-layer" fieldbus reference model described in IEC 61158？1.
Throughout the set of fieldbus standards, the term "service" refers to the abstract capability provided by one layer of the OSI Basic Reference Model to the layer immediately above. Thus, the data-link layer service defined in this document is a conceptual architectural service, independent of administrative and implementation divisions.
