The invention belongs to the technical field of nuclear power station PLC teaching and particularly relates to a general teaching device for the PLC logic controller of a nuclear power station. The invention aims to design a set of portable and interesting PLC general teaching device. The device comprises two kinds of PLCs commonly used in a nuclear power station. The two kinds of PLCs share one set of peripheral circuits. By means of an Intouch upper computer equipped with an integrated computer, the interesting actual combat drilling is carried out according to the prompts of the upper computer. The switching value input, the switching value output and the analog quantity input of the PLC are explained step by step. A PLC online teaching plan with pictures and texts is matched, so that atrainee can eliminate worry about the PLC in a short period of time and quickly master the operation essentials of the PLC. The device is characterized by comprising a S7-300 type PLC, a GE 90-30 type PLC, a power switch, a
