A device for testing a PLC system is provided to reduce a time for a test and software correction by reproducing a condition of a production process irrespective of hardware conditions of a factory automation field. A device for testing a PLC(Programmable Logic Controller) system includes an analog input/output unit(110), digital input/output units(120,130,140), a pulse generator(160), and a PLC input unit(150). The analog input/output unit includes an analog input adjusting unit for inputting an analog signal to the PLC system and an analog output display unit for displaying an analog signal from the PLC system. The digital input/output units adjust the digital signal, input the adjusted digital signal to the PLC system, and display a digital signal from the PLC system. The pulse generator inputs a pulse signal to the PLC system. The PLC input unit inputs a speed control signal to the PLC system.
