摘要
提出了一种适合于基金会现场总线中客户/服务器型通信的连接管理方法,该方法既扩展应用了现场总线系统的同步应用时钟,又使客户/服务器型通信关系的连接管理具有以下的特点：a. 没有用于连接建立和释放的专用报文, b. 不需要用于建立连接的等待时间, c. 现场设备发生故障后,能快速恢复通信.
A connection management method suitable for client/server communications in foundation fieldbus is presented. Wits this method the application of synchronized clocks to fieldbus is extended and the client/server communications are endowed with the following characteristics: (1) no proprietary message for connection setup or release, (2) no connection setup latency, (3) immediate resumption of communication after a fieldbus device failure.
