摘要
本文提出了一种新的用Atmel89c2051仿真PLC控制的方法,允许用户先按梯形图对控制对象编程,这对继电器控制较为熟悉的电气技术人员来说提供了方便。而且,用此方法已经成功做成专用的功能电路模块。由于该仿真电路板价格低廉并具有柔性,可以被开发成产品,也十分适合于PLC控制的演示实验。
This paper presents a new emulation method for PLC control with Atme189c2051. It provides a way for user to program the controlled object according to ladder first.It also provides convenience for electric technician who is more familiar with relay control. Further more, Dedicated function circuit has already been implemented using this method. Due to low-cost and suppleness the emulation circuit may turn into the product, and also suits for making a demo experiment on PLC control.
