A system and method for setting a software option of a numeric control device (10), by which a user cannot set the options without permission and a cost regarding option configuration may be recovered by a maker. A maker PC (12) generates option setting data for setting bit information to one or zero, based on a name or a number of a software option to be set, in order to make the function of the software option valid or invalid. This data is encoded or encrypted by using a unique identification number (10a) of a control device (10). The control device (10) reads and decodes the encoded software option setting data, in order to set data of the corresponding memory address and bit number in the control device (10) to one or zero. By using the unique identification number (10a) of the control device (10), only the control device (10), the software option setting data of which is required, can decode the encoded data.
