PURPOSE:To omit the replacement of the control programs when an evaluating control program is evaluated by adding a control program storing function to an auxiliary control program storing part together with a function which loads a control program into a device from said control program storing part. CONSTITUTION:An auxiliary control program storing part 14 is provided to store one of plural control programs in addition to an SCU control program storing part 11, an EPU control program storing part 12 and an IOP control program storing part 13. A control program loading means 18 is started by a storing part selecting means 16 decides whether a control program should be taken out of the part 11 or the part 14 based on the memory information on the means 16 when a loading request is given for the control program of a system control unit SCU, for example. In this case, the control program is taken out of the part 11 and loaded into an SCU2. Thus it is not required to carry out the replacement of control programs to be needed at least twice at evaluation of control programs. |
