ポーリングデータ送信装置。 In a node controller that transmits measurement data to the host controller when called from the host controller, a data change point detection means for detecting a change point in measurement data and a time point at which the change occurs; The polling data is characterized in that it comprises a transmission control means for transmitting measured data at the time of calling, a change point in the measured data from the time of the previous call to the time of the current call, and the time of the change to the host controller. Transmitting device.
