Abstract

PURPOSE:To synchronize subsystem-to-subsystem free communication with general communication from one subsystem to N subsystems, and to facilitate the detection of an abnormal subsystem, by checking states of reception-objective subsystems, which are to receive data, all the time by a command response system. CONSTITUTION:Subsystems 1-0-1-2 of the multisystem computer system are connected in parallel via the single bus of data line C and control line D to perform general communication with systems 1-0-1-2. Those systems 1-0-1-2 are provided with control circuits 5-1-5-2, transmitting and receiving circuits 6-0-6-2 and 7-0-7-2, and discriminating circuits 8-0-8-2. For the general communication, a start sequence for a sequential check on the states of reception-objective subsystems which are to receive data by the command response system, a function of sending data at a time after the execution of the start sequence, and a completion sequence for a sequential check on the states of the reception-objective subsystems synchronize the general communication.
