Abstract
PURPOSE: To prevent service performance from deteriorating by counting the frequency of faults of a system corresponding to its fault information and then by disconnecting the unit from online operation by judging the unit in trouble when the frequency exceeds the predetermined reference value of the unit.
CONSTITUTION: Fault deciding memory unit 12 connected to central controller 11 is provided with memory area 13 for the frequency of faults and memory area 14 for a reference value, and controller 11 exercises control over input controllers 1aW 1N and output controllers 2aW2M in addition to a supervision. Further, controller 11 exercises control over transfer controllers 3a and 3b and a supervision over their operations, and controller 11 counts the frequency of faults of units under the control of controllers 1aW1N, 2aW2M, and 3a and 3b to update the memory frequency in memory area 13. Then when the frequency of faults of the lower rank units exceeds the reference value stored in memory area 14, the lower rank unit is judged in trouble and disconnected from online operation, thereby preventing service performance from deteriorating.
