摘要：
The junction device includes a first error detection means that detects a transmission error by monitoring the periodic reception of a first communication frame, and a state switching means that switches, when a transmission error is detected by the first error detection means, a state of the junction device to either a first state in which the signal output from all of the functional units connected to the junction device is disabled or a second state in which the signal output from some of the functional units connected to the junction device is continuously updated based on the configuration of each functional unit connected to the junction device.
