高速FF现场总线工作在TCP/UDP协议之上 ,这使得HSE总线比H1总线有更高的通信速率。套接字映射协议层SMPM是HSEFF总线中重要的一层 ,它利用套接字进行通信 ,本文介绍了FF怎样利用套接字进行通信以及SMPM的具体实现过程。
High-speed FF fieldbus work in the TCP / UDP protocol, which makes the HSE bus has a higher communication rate than the H1 bus. Socket Mapping Protocol Layer SMPM HSEFF bus is an important layer, which uses sockets for communication, this article describes how FF sockets to communicate and SMPM concrete realization of the process.
