<p>PROBLEM TO BE SOLVED: To provide a control logic operation confirming device capable of confirming the operation of the control logic of a digital type controller without needing any hard wired connection with the digital type controller to be tested and without needing any logic generation for simulation. SOLUTION: This device is provided with output wire gauge areas 20 and 21 arranged at an internal memory 2 of a digital type controller 5 for storing the arithmetic result of a control logic 3, a return logic 4 for using the arithmetic result stored in the output line number areas 20 and 21 as an input, and input line number areas 22, 23, and 24 for storing the arithmetic result of the return logic 4. Then, the arithmetic result stored in the input line number areas 22, 23, and 24 is used as the input of the control logic 3 so that a closed loop can be constituted, and the increase/decrease of a signal is simulated by the return logic 4 so that the operation of the control logic 3 can be confirmed.</p> |
