1. A communication device that communicates, in a first cycle, with sensors connected through a network to acquire, from each of the sensors, measurement data measured by the sensors in data acquisition cycles longer than or equal to the first cycle and to store the measurement data in a storage, the communication device comprising:
a grouping section to classify the sensors into groups based on the data acquisition cycles, to acquire the measurement data from the sensors classified into the groups, and then to reclassify one sensor of the sensors into a different group of the groups when determining that a maximum size of data to be received through the network per first cycle exceeds a threshold for a communication band of the network; and
a memory map generator to calculate, based on the data acquisition cycles and the groups resulting from the classification, a timing and an address to store the measurement data in the storage.
