The invention discloses an automatic test system and method for industrial production process control logic, and belongs to the technical field of industrial control. The system is composed of a test basis information setting module, an input signal generation module, a data collection module and a comparison and determination module. Test data generated by a numerical value signal input module are used as the input of the tested control logic. The method comprises the steps that signals from [0,0,0...0] to [1,1,1...1] and signals from [1,1,1...1] to [0,0,0...0] are sequentially input for the tested control logic automatically, whether the tested control logic is correct or not is automatically judged according to output signals which are sequentially and correspondingly generated, the signals input every time, the corresponding output signal and the test conclusion are recorded, the ergodicity of the control logic test can be achieved, control logic errors can be automatically recognized, and the automatic test system and method have the advantages of being high in credibility, repeatable, traceable and high in efficiency and accuracy.
