PROBLEM TO BE SOLVED: To construct a sequence control part capable of easily and inexpensively attaining construction, expansion of a control system and also flexible for various system configurations. SOLUTION: This numerical control device is provided with a numerical control parts 10 of multiple systems. It is provided with interface parts with a sequence control part 20 by every system. Systems to be controlled by the respective sequence programs (ladder, 1, ladder 2, ladder 3) having independent input/output signals stored in the sequence control part 20 are allocated to interfaces by every system. The numerical control part 10 and the sequence control part 20 transfers signals via the allocated interface parts of the systems. A control system is freely constructed without providing a new programmable controller as shown in figures (a), (b) by changing allocation. COPYRIGHT: (C)2004,JPO&NCIPI
