摘要
LonWorks网络中,通常用上位机监控各个智能节点的工作。上位机和智能节点间的消息传送是通过LNS DDE服务器来进行的。本文提出了一种上下位机通信的实现方法,该方法以LNS DDE服务器为基础,简便、可靠,且具有良好的通用性。
The supervisor is often used to monitor and control the smart nodes in LonWorks network. Messages between the supervisor and the smart nodes are transmitted through LNS DDE server. In this paper, an implementation method of communication between the supervisor and the smart nodes is presented. This method which is based on LNS DDE server is convenient, reliable and of general purpose.
