PURPOSE:To attain the unmanned operation of a decentralized processor even in a hardware or software trouble mode, by performing automatically the recording of troubles and the restart of operation with no intervention of an operator. CONSTITUTION:The power supply of a decentralized processor DPU is applied to operate the DPU through a center system CPU. Then a loading action is through with the initial program of the DPU after about 3min from application of the DPU power supply. Thus the operation of the DPU is started. When a hard ware or software trouble occurs at the DPU in its operation mode, the control is shifted to a trouble processing mechanism TPU. Then the trouble information is recorded to an external memory EMU, and a stop instruction is delivered to a remote power supply controller RPU for restart of operation of the DPU. The RPU detects the stop instruction and cuts off the power supply of the DPU. Then the DPU restarts its operation automatically since the start command is always delivered to a communication circuit from the CPU after the operation of the DPU is started. |
