PURPOSE:To control input/output (I/O) equipments based upon various combination by a common control program by optionally assigning interruption machine numbers to various optional I/O equipments at every system. CONSTITUTION:An interruption input selecting circuit 12 is connected between an interruption controller 11 and I/O equipments 13A-13X. The circuit 12 switches connection relating to an interruption input from the I/O equipments 13A-13X to the controller 11. Assigning information for the input interruption machine numbers INT0-INT7 is previously stored in a hardware function data storage part 17 at every system, e.g. At the time of turning on a power supply, a microprocessor 10 starts a selecting information initializing processing part 18 and sets up the data of the storage part 17 in an interruption selecting register 14. |
