PLC模拟机械控制凸轮的实现方法

The Realization Method of PLC Simulate Mechanical Controlled Cam

PLC的中文含义为可编程控制器,是一种新型的工业控制装置,以其可靠性极高、使用极为方便的特点被广泛应用于工业自动化领域。用PLC替换机械控制凸轮实现顺序控制的方法,既克服了使用机械控制凸轮存在的调整误差等缺点,又具有很强的抗干扰能力和柔性。本文详细介绍了这种方法的设计原理,并画出了I/O连接图及梯形图。

PLC is a new pattern industrial controlled device. It抯 wildly used in industrial automation for its reliability and facility. It not only can overcome the disadvantage in the adjust error by simulate cam-mechanical controlled, but also possess the ability of anti-jamming and flexibility. This article introduces the design theory and the connecting and echelon plot.
