摘　　要：在PLC系统应用中,梯形图的程序设计往往是最主要的问题,通过相应的实例论述梯形图程序的4种设计方法:时序逻辑设计法、状态表设计法、顺序控制设计法及经验设计法。这些设计方法汇总可编程控制器作为开关量控制系统通用的电路设计法,对教学和工程实践具有一定的实用参考价值。The trapezoidal chart programming often is the primary question in the PLC system application. The paper specifies four design methods through the corresponding example in the paper,including sequential logic design, condition table design, sequential control design and empirical design. These methods which compile the general circuit design of the PLC to take the switch quantity control system have certain practical reference value for the teaching and the project practice.
