Abstract

PURPOSE:To increase the reliability of a hierarchy system, by transmitting an initial program set command after a reset signal is given from a host computer at a failure of a subordinate computer to confirm the opration of the subordinate computer. CONSTITUTION:When a CPU9 of a subordinate computer 8 stops the operation, a watchdog timer 14 transmits a time-up signal to a CPU2 of a host computer 1 via transmission circuits 12 and 5. The CPU2 receives it and it judges that the CPU9 is in failure, and a reset signal is transmitted from a command generating circuit 6. This signal is received at an command receiving circuit 13 and a reset instruction signal is given to a reset signal generating circuit 16. The circuit 16 transmits the reset signal to an initial program set IPL signal generating circuit 17. The circuit 17 generates an IPL signal and transmits it to the CPU9, and the CPU9 loads the initial program stored in an auxiliary memory 15. Thus, the subordinate computer 8 executes the IPL operation.
