触摸屏在PLC工业系统中的应用

Use of touch panel in PLC industrial system

介绍了可编程逻辑控制器（ＰＬＣ）应用系统的特点和不足，阐述了触摸屏的性能、特点及在 ＰＬＣ系统中的应用，对传统的ＰＬＣ系统和使用触摸屏的ＰＬＣ系统进行了比较，提出了使用触摸屏 简化ＰＬＣ系统的新思路．对工业系统的设计具有很大意义．

The characteristics and deficiency of Programmable Logical Controller (PLC) are introduced. The performance and use of the TP in PLC system is set forth, and the traditional PLC system is compared with the PLC system used of TP. A novel idea that makes use of TP to facilityate PLC system is proposed in this article, which has great significance in the design of industrial system.
