标准摘要
[中文适用范围]： 本国际标准规定了促进用于与 ISO/IEC 14908-1 配合使用的联网控制系统在电力线介质上交换数据和控制信息所需的所有信息。本国际标准建立了一组最低限度的合规规则。在遵守系统内规则的前提下，它不排除提供扩展服务。标准的意图是允许扩展服务（由用户定义）共存。本标准的某些方面在其他文件中定义。这些文件在相关处被引用。在引用的标准与本国际标准冲突的情况下，本 ISO/IEC 14908 部分将占主导地位。 [外文原描述]： ISO/IEC 14908-3:2011 specifies the control network Power Line (PL) channel and serves as a companion document to ISO/IEC 14908-1. It presents the information necessary for the development of a PL physical network and nodes to communicate and share information over that network. ISO/IEC 14908-3:2011 covers the complete physical layer (OSI layer 1) including the interface to the Medium Access Control (MAC) sublayer and the interface to the medium. It includes parameters specific to the PL channel type, even though the parameters may be controlled at an OSI layer other than layer 1. ISO/IEC 14908-3:2011 also provides a set of guideline physical and electrical specifications for the power line environment as an aid in developing products for that environment.
