PURPOSE:To attain efficient design by forming input information as list type data construction combining logical formulas so as to be optional cell structure through a cell pointer. CONSTITUTION:In the configuration of a sequence control circuit designing device, the user inputs data such as the sequence operation of a sequence control circuit from a design data input device 2c. A central processing unit (CPU)1 processes the input data in accordance with a sequence control circuit designing program in a program storage device 4b and stores the designed result and the data of sequence operation to be designed in a designed result storage device 4a and a sequence operation storage device 4c respectively. In respect of the data construction in said designed result storage device 4a, a ring pointer designates the list type data construction combining optional cell structures as the value of a control output. Consequently efficient design is attained. |
