摘要
介绍了一种擦窗机电气控制系统的实现方法,此方法通过分时传送循环扫描的方法解决了2个PLC之间的信号线有限,却要用更多的信号来控制擦窗机工作的问题.其特点是使用成本低,性能稳定可靠.
Introduces a realization method of electrical control system of window cleaning equipment. By circular scan and timing transmission means. It resolves the problem of transmitting more signals between PLC and PLC by using limited wires to control the work of cleaning window equipment. Its characteristics is cost less and reliability.
