Summary:PROBLEM TO BE SOLVED: To provide a system for securely avoiding the incorrect down loading of a firmware file which is to be down-loaded, and realizing firmware down loading to the plural devices of the same logic type or firmware down loading on a device with exchangeability. SOLUTION: When the down loading firmware file for a device A1 is generated, the logic identifier 3 of the device Al is folded in the firmware file and it is stored in a storage medium 9. In down-loading the firmware file from an external controller 8 to the device A1, the logic identifier of the firmware file and the logic identifier 3 which is set in the device A1 are read and are compared. When the logic identifier of the firmware file is matched with the identifier 3 of the device A1, down loading is executed. When they are not matched, down loading is not executed. An execution result is displayed on a display device 11.
