因此，PLC在我国的应用潜力远没有得到充分发挥。
我国工业企业的自动化程度普遍较低，PLC 产品有很大的应用空间，如机械行业80%以上的设备仍采用传统的继电器和接触器进行控制。
随着竞争的日益加剧，越来越多的小型企业将采用经济、实用的自动化产品对生产过程进行控制，以提高企业的经济效益和竞争实力。
在自动化生产线上，有些生产机械的工作台需要按一定的顺序实现自动往返运动，并且有的还要求在某些位置有一定的时间停留，以满足生产工艺要求。
用PLC程序实现运料工作台自动往返顺序控制，不仅具有程序设计简易、方便、可靠性高等特点，而且程序设计方法多样，便于不同层次设计人员的理解和掌握。
关键词：PLC 自动化顺序控制Abstract：Chinese large and medium-sized businesses generally dopted advanced automated system for production process control, but most small enterprises were not yet available automation system and products to the production process control. Therefore, PLC application in our country is far from potential into full play. Our industrial enterprise automation degree is generally low, and the application of PLC products have very big space, such as mechanical industry more than 80% of the device is still using traditional relays and contactor controlling. As more and more fierce market competition, more and more small businesses will adopt economic and practical automation products on production process control, in order to improve the economic benefit of enterprise and competitiveness.according to certain order the realization of automatic round-trip sport, and some still requirements in some places have certain time stays, to meet the production process requirements. With PLC program realization shipped materials workbench automatic round-trip sequence control, not only has the program design of simple and easy, convenient, thereliability high characteristic and the program design methods are various, facilitate different levels design personnel understanding and mastering.Keywords：Programmable Logic Controller ，atomation ，squence control1一、绪论：在自动化生产线上，有些生产机械的工作台需要按一定的顺序实现往返运动，并且有的还要求在某些位置有一定的时间停留，以满足生产工艺要求。
