Manufacturing conditions are saved in a first storage unit. The manufacturing conditions are transmitted from the first storage unit to a second storage unit to be stored in the second storage unit. A product is manufactured based on the manufacturing conditions stored in the second storage unit. After the product is manufactured, the manufacturing conditions are erased from the second storage unit. Thus, maintenance and inspection can be easily performed, and leak of information about the manufacturing conditions can be prevented. |
