基于TCP/IP协议的智能前端在宣化热电的应用

分析了RS协议的不足和TCP/IP协议的优势,通过在智能前端上采用TCP/IP协议代替传统RS协议,实现了智能前端通讯模式的飞跃.同时,第一批基于TCP/IP协议的智能前端在宣化热电大规模投运中取得了良好的实践效果.;The inadequacies of RS agreement and advantages of TCP/IP protocol are analyzed.The smart IO using TCP/IP protocol,instead of RS agreement,realize smart IO communication mode leap.The first batch of TCP/IP-based smart IO in Xuanhua Thermal Power Plant also achieves good effect in practice
