基于三菱PLC步进指令对交通信号灯的控制

Control of Traffic Light Based on Mitsubishi PLC Step Instruction

文中以三菱PLC指令系统的步进指令控制交通信号灯为例,详细介绍了步进指令的设计方法及其流程图。结果表明,对于顺序控制,步进指令具有条理清楚、编程方便、直观、易于实现等特点。

Taking the control of traffic light based on Mitsubishi PLC step instruction system for an example,the paper introduces the design method and flowchart of step instruction.The result shows that the step instruction has the charateristics of clarity,convenient programming,intuition and easy implementation for order control.
