PURPOSE:To provide the down load system which guarantees the control after switching of firmware and easily detects mis-designation of a module to be loaded down. CONSTITUTION:This system consists of a higher-order device 1 which indicates down load, a storage device 2 where plural files consisting of modules with module classification flags added and a firmware table where file names to be loaded down are recorded and stored, and plural information processors 3 to 5 provided with the function which reads out the file indicated by the higher-order device 1 from the storage device 2 and compares the value obtained by integrating the module classification flags of modules constituting the read- out file with the value obtained by adding the module classification flags of all modules to be loaded down which are beforehand stored and checks whether all of required modules are completely loaded or not.
