可编程序控制器梯形图的逻辑设计方法

The Logic design of Ladder-Shaped graph for Programable contraller

梯形图是可编程序控制器的重要程序设计方法,但它的设计方法还很少有人总结。本文提出二种梯形图的逻辑设计方法在工厂电气控制技术中对推广可编程序控制器的应用将有一定的参考价值。

Two,ladder-shape graph methods for logilc design of programmable controllers (PC)are presented in this paper. They wiclcl faailitate the application of(PC)for the in contral of manufac- turing processes.
