PURPOSE:To improve the efficiency of maintenance and management by reading the program of a processor and collating a program stored in a memory means with one program of plural processors read out by the memory means. CONSTITUTION:A system control processor 11 monitors time information stored previously in a memory part 12 and the time of a system. When the time information in the memory part 12 is coincident with the time of the system, the program data of a local processor 21 is read out through a data transfer bus 16 and stored provisionally in the memory part 12. In the same manner as the local processor 21, the program data of a local processor 22 is read out through the data transfer bus 16, and collated with the program data of the local processor 21, which is already stored in the memory part 21. Thus the collation of program data can be automatically carried out between the same type of processors, thereby improving the efficiency of maintenance and management.
