CHANNEL FAULT PROCESSING SYSTEM

摘要

PURPOSE:To shorten the fault processing time by giving continuously the fault processing start instructions to an individual control part from the 1st channel common control part when such a fault that is unable to specify a channel occurs. CONSTITUTION:If a hardware fault that is unable to specify a channel number is detected by a fault processing control part 25 at a time point C, the information on this fault is given to the 3rd microprocessor 10. Then the part 25 gives an instruction to the 1st microprocessor 8 to interrupt or complete the relevant process. While a microprocessor control circuit 23 controls a selector 18 so that a fault processing start address is supplied to an address register 17 by a certain timing and also by the following timings M+1-M+15 respectively. Then the circuit 23 performs control so that the address outputted from a shift register 19 is supplied to the register 17.
