ABSTRACT:
A device for testing a product includes: a programmable logic controller (PLC) for loading or unloading a mechanical part of a test target product at a regular position suitable to a test environment; a personal computer (PC) for performing bidirectional communication through communication ports by generating a test control signal in order to test the test target product; a loading detection unit which is connected to the communication port and to an output terminal of the programmable logic controller (PLC), and which detects whether the PLC loads the test target product, and which informs the detected information to the PC; an unloading control unit which is connected to the communication port and to an input terminal of the PLC, and which applies an unloading signal to the PLC by receiving a test completion signal through the communication port, and which unloads the test target product from the PLC, and an error alarm unit which receives an error generating signal reporting occurrence of an error when testing the product through the communication ports, and which alarms the error occurrence. As a result, the problem of correcting programs for measuring, controlling and testing, as used in the PC and the program of the PLC, can be solved, thereby reducing the economic burden in manufacturing the device for controlling the mechanical part of the product.
