摘要
在中小型工控项目的系统设计方案中,采用PLC控制的方案存在诸如成本、维护及占地面积等方面的问题。本文结合一个工控实例,给出了一种采用串口设备服务器作为连接与转换上、下位机之间的桥梁来构建中小工控项目的解决方案。
Among the system design schemes of middle-small scale industrial control project,the scheme that adopts PLC to control has some disadvantages such as cost,maintenance and area,etc.In this article,combined with a practical project,a valuable scheme which adopts serial port device network server as connective bridge to connect PC and controllers is presented.
