| Abstract: | 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. |
