PLC梯形图编程规则略谈

可编程控制器(Programmable Logi Controller)简称为PLC,是以微处理器为核心,目前已被广泛地应用于各种机械和生产过程的自动控制中。PLC技术已成为现代控制技术的重要支柱。用PLC梯形图编程来控制继电器电路就成为迫切需要解决的问题。(以三菱FX2N系列PLC为例说明)

Programmable Controller (Programmable Logic Controller) is referred to as PLC, is a microprocessor as the core, has been widely used in all kinds of machinery and automatic control of production process. PLC technology has become an important pillar of the modern control technology. With PLC ladder diagram programming to control the relay circuit becomes the urgent need to solve the problem. (Mitsubishi FX2N series PLC as an example to show)
