高速FF现场总线的会话层(FDASession)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。Session是HSEFF总线中重要的一层,它为FMS消息和FDA消息提供了通信通道,本文详细介绍了Session的具体实现过程。
The high-speed FF Fieldbus session layer (FDASession) work in the TCP / UDP protocol, which makes the HSE bus has a higher communication rate than the H1 bus. Session is an important layer in the HSEFF bus, which provides communication channels for FMS messages and FDA messages. This article details the specific implementation of Session.
