ISO/IEC 14908-1:2012规定了局域网的通信协议。该协议为网络控制提供点对点通信，适用于实现点对点和主从控制策略。ISO/IEC 14908-1:2012描述了第2层至第7层中的服务。在第2层（数据链路层）规范中，它还描述了介质访问控制（MAC）子层与物理层的接口。物理层提供了传输介质的选择。 ISO/IEC 14908-1:2012中描述的接口在物理层支持多种传输介质。在第7层规范中，它包括应用程序用来交换应用程序和网络管理数据的消息类型的描述。

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.
