Abstract
PURPOSE: To avoid the incapability of the system operation by providing the switch to the priority control circuit and then varying temporarily the interruption sequence in case the fault takes place.
CONSTITUTION: Switches 6a and 6b are provided along with their wiring given. Switches 6a and 6b are usually turned toward the side shown by the solid lines. In this case, the sequence of the I/O is set as 3A, 3B...3N. Then the highest-rank I/O 3A becomes faulty, and switches 6a and 6b are turned toward the dotted line side. As a result. I/O 3B is set to the highest rank, and 3A is set to the lowest rank each. Thus I/O 3BW1/O 3N are never affected by the fault of I/O 3A, and accordingly the system can secure the operation by excluding 3A.
