摘要
为解决工业上电动机或电磁阀短时间工作、长时间停止的循环工作问题 ,现提出三种方案 .它是对可编程序短时延时网络的总结和提高 .下面将从设计程序、梯形图、工作原理时序图。
For settle to the industry electric motor or electromagnetic valve frequent work in industry , that needs long time time-lapse network to work again after stopped for long time.The three kinds of ways are summing up and improving of the program delay-time network . Now we will have a particular introduce about design programme, ladder-sharped plot , task principle time squence chart , programing instruction.
