摘要
可编程序控制器的软元件是程序设计的基础.软元件的实质是存储器RAM中的一些位或存储单元。软元件与传统的继电器接触器的硬元件在结构和原理及应用方面有很多相似之处。本文以常用的三菱公司的PLC进行了可编程控制器的软元件应用分析。
The soft component of PLC is the the basis for program design and the essence of it is some of the bits in RAM memory or storage unit.There are so many similarities in the structure,principles,applications between soft component and the traditional hard components.In this paper,take the Mitsubishi PLC programmable controller for the application of the soft component analysis.
