摘要
介绍一种应用于过程控制系统的基于过程可视化接口PVI的通信方式,采用此通信方式,应用程序开发人员无需过多考虑底层通信线路和协议,直接面向控制变量,编程方便。基于快速以太网和PVI的通信,速度可达100Mbps,既能满足控制的实时要求,又具有扩展性好、开发周期短的特点。
This paper discusses a communication method, which is based on Process Visualization Interface (PVI) and can be applied in Process Control System (PCS).By this method,it is not necessary for the program developer to consider the detailed communicating route and protocol too much.It is convenient to program because all facing the developer is just the control variables.With the rate up to lOOMbps,Communication method based on ETHERNET POWERLINK and PVI can not only meet the real-time requirement,also make the application extendable and development cycle short.In a word.
