PURPOSE:To process transmitting and receiving information in order of a priority degree for each purpose by providing a transmitting and receiving information connecting wiring between plural CPUs, respectively, and providing a priority degree table in which a priority degree for each purpose of the transmitting and receiving information is mentioned, on each CPU. CONSTITUTION:A CPU1 and 2 are provided with priority degree tables 12 and 22, and a priority degree is given to this priority degree tables 12 and 22 in accordance with an information purpose. Also, weighting is displayed between the CPUs. When the CPU1 transmits a purpose, for instance, a fault processeing request to the CPU2 through an interrupting line 3-1, the CPU2 receives this request by a processing part 21, refers to the priority degree table 22, recognizes that a priority degree of this request is high, and executes a processing of this request. The interrupting line 3-1 and a data line 4-1, and an interrupting line 3-2 and a data line 4-2 are used exclusively for from the CPU1 to the CPU2, and from the CPU2 to the CPU1, respectively. |
