PURPOSE:To facilitate programming operation by inputting an output element on an input device and processing them when the output element in a ladder diagram is enlarged and processed. CONSTITUTION:An automatic computer program generator 1 consists of a CRT 19 as a display device, keyboard 20 as the input device, CPU11, etc., and a generated program is displayed as a ladder diagram on the CRT19 and also transferred to a controller 2 and an external storage device (EPROM4, etc.). The screen of the CRT19 is sectioned into a ladder and a reference area, and a circuit in the ladder diagram displayed in the ladder area is enlarged and processed. When this enalarged circuit is generated, the circuit part (part A in the figure) except an output element 101 is generated and then the target output element 101 is inputted on the keyboard 20 to enlarge the output element 101 automatically to a size conforming to the circuit A. |
