摘要
针对常用机型的使用场合及特点，提出了一套简便的功能和节点扩展方法，使中小型ＰＬＣ机不但能处理开关量也能处理模拟量。
According to used filed & property of PLC common type, this paper presents a simple method of expanding function & points of PLC, which makes small & middle PLC not only process switch but also analog & expand the application range of PLC. It is useful for engineering.
