Abstract
PURPOSE:To rapidly and easily evaluate the operation of firmware by using an I/O device connected to a central control device to substitute a readable/ writable memory for either one of read-only memories (ROMs) in a duplicated system. CONSTITUTION:A system control circuit (P-CTL) 17 is connected in substitution for a ROM(1) 11b stored in a firmware of a duplicated device in a preparatory system, contents stored in a ROM(0) 11a in a driving system is transferred to a RAM 171 in a control circuit of the preparatory system on the basis of an I/O instruction from the central control device, duplicated devices in both the preparatory system and driving system are switch to each other, and in the duplicated device of the new driving system, at least the normality of the firmware is evaluated by said I/O instruction. Thus, the operation of the firmware can be rapidly and easily evaluated.
