摘要
PLC实验实训设备上有抢答器和各种循环控制实验,其输出控制很有规律,为了方便学生掌握PLC梯形图设计思路,文章以抢答器PLC梯形图设计为例,用具有约束条件的真值表来辅助设计逻辑输入输出关系。该方法具有通用性,对PLC的教学和实验、课程设计、毕业设计都具有很好的借鉴作用。
PLC is equipped with first answer device and various circulative control experiment with disciplinary output control. The author applies the truth table to assist the design of logic input and output, taking the design of PLC ladder diagram of first answer device as an example. This method can be used widely and taken as references to PLC teaching, experiment, curriculum project and graduation project.
