Detection device for logic control program of logic controller

The detection device for the logic control program of the logic controller comprises a first logic controller and a second logic controller, and the first logic controller is a logic controller of a detected program; a plurality of logic output ports of the first logic controller are sequentially connected with a plurality of logic input ports of the second logic controller, and a plurality of logic output ports of the second logic controller are sequentially connected with a plurality of logic input ports of the first logic controller. A logic switch is connected to a logic input port, used for detecting the switching value, of the first logic controller. According to the detection device for the logic control program of the logic controller, a platform for testing the logic program of the logic controller can be constructed through the second logic controller and the logic switch, the number of devices is small, the structure is simple, and the universality is good; the problems of long period and high cost
