标准摘要
[中文适用范围]： 本规范适用于局部区域控制网络的通信协议。该协议提供网络化控制的对等通信，并且适合实现对等和主从控制策略。本规范描述了分层结构中第二到第七层的服务。在第二层（数据链路层）规范中，还描述了介质访问控制子层与物理层的接口。物理层提供了传输介质的选择。本规范中描述的接口支持物理层上的多种传输介质。在第七层规范中，包括了应用程序用来交换应用和网络管理数据的消息类型的描述。 [外文原描述]： ISO/IEC 14908-1:2012 specifies a communication protocol for local area control networks. The protocol provides peer-to-peer communication for networked control and is suitable for implementing both peer-to-peer and master-slave control strategies. ISO/IEC 14908-1:2012 describes services in layers 2 to 7. In the layer 2 (data link layer) specification, it also describes the Medium Access Control (MAC) sublayer interface to the physical layer. The physical layer provides a choice of transmission media. The interface described in ISO/IEC 14908-1:2012 supports multiple transmission media at the physical layer. In the layer 7 specification, it includes a description of the types of messages used by applications to exchange application and network management data.
