Abstract
According to an embodiment of the invention, a data transmission device that includes a communicator and a controller is provided. The communicator is connected to a network and communicates with another device via the network. The controller transmits, from the communicator to the other device, a data set including data of at least one item in the case where the data of the at least one item has changed from the state of previous interval; and the transmitted data set includes the data having the changed state. The controller acquires the data of the at least one item at a first interval, and performs the transmitting of the data set to the other device at a second interval or at a frequency less than the second interval by updating the data of the at least one item at the second interval; and the second interval is slower than the first interval.
