摘要
通过分析彩灯的控制要求,设计了基于西门子S7-200可编程控制器的控制方案,对控制系统硬件进行了设计,选择了外围元器件,进行了I/O分配及外部接线,同时,利用其丰富的指令,给出了能够实现功能的四种控制方案,分析了使用效果。
A control scheme based on S7-200PLC is designed through the analysis of colored lights control requirements.Peripherals are selected and are connected to the PLC.At the same time,four design schemes are given.The application effect of the four schemes is analyzed in this paper.
