Claim 2:
3. The anti-fraud control system according to claim 2, wherein
in the first error monitoring device,
when detecting that no error notification frame for notifying of an occurrence of an error in the corresponding one of the branches is received from the one or more second error monitoring devices with respect to the frame subjected to the error and included in the error notification frame transmitted by the first frame transmitting and receiving hardware unit, the first hardware error detector causes the first frame transmitting and receiving hardware unit to transmit an mode transition frame for shifting the one or more second error monitoring devices to the invalidation mode, and
in each of the one or more second error monitoring devices,
when detecting that the second frame transmitting and receiving hardware unit has received the mode transition frame, the second hardware error detector determines that no error is detected in the corresponding one of the branches and shifts the second error monitoring device to the invalidation mode.
