Conventional state change detection methods using such methods have the disadvantage that shortening the period of the transmission timing signal increases the transmission traffic and increases the processing load of the state change occurrence count value on both the transmitting and receiving sides. Furthermore, in an attempt to suppress this drawback, extending the period of the transmission timing signal reduces the transmission traffic, but has the drawback that it becomes impossible to grasp the occurrence of time-dependent state changes.
