PURPOSE:To shorten the time required to diagnose the normalcy of initial program codes by reading a program out of a control storage, generating check codes by a processor and collating the check codes with check codes which are stored on a floppy disk previously. CONSTITUTION:The program which is stored in a buffer memory 7 is transferred to and stored on the control storage 4 of a controller 1, a control means 10 reads the stored program out, and a check code generating means 11 generates the check codes according to all data of the program read out of the control storage 4. Then the check codes are collated with the check codes which are generated by the same method by a check code generating means 11 and stored on the external storage means 12 previously. It is decided that the initial pro gram is normal when they match each other or abnormal when not. Consequent ly, the time required to diagnose the normalcy of the initial program loading can be shortened. |
