Abstract

PURPOSE:To restart a subordinate computer by transmitting special data from a host computer which detects a system fault of the subordinate computer to the subordinate computer and by processing fault analytic data from the subordinate computer. CONSTITUTION:A host equipment 1, once detecting a fault of a subordite equipment 5, transmits a special telegraphic message to the subordinate equipment 5. On receiving the telegraphic message, the communication controller 4 of the subordinate equipment 5 interrupts a processor 6 and sets telegraphic message data in an interface register 12. As a result of this interruption, the processor 6 is placed in a state RUM and an ROM to be started is determined. When the telegraphic message data is the storage contents transmission request of the subordinate equipment 5, the contents of a main storage and an auxiliary storage are all sent to the host equipment 1, which while storing the software of the subordinate equipment 5, collates the data, thereby analyzing the fault. When the telegraphic message data is a request to transmit normal data from the host equipment 1, the subordinate equipment 5 receives the normal data to return to the writing operation of the main storage and auxiliary storage automatically.
