Controller Link和串行通讯技术在PLC监控系统中的应用

Application of Controller Link and Serial Communication Technique in PLC Industrial Control System

根据常用的串行通讯和CLK通讯的通讯协议,计算和比较了 2种方式的通讯时间。CLK通讯方式的通讯速度比串行通讯方式提高 2 0倍。

This paper calculated and compared time of communication based on protocol of serial communication and CLK communication.CLK communication is widely used in largescale system because of its fast transfers speed.
