Abstract:
This data control device (20) includes: an analog signal input interface (243) which receives an analog signal from a first apparatus (63); a communication interface (260) which receives association information that indicates addresses of a plurality of respective storage areas (251, 252) included in a storage unit (250) and condition values associated with these storage areas (251, 252); a data control unit (210) which writes a digital value generated from the analog signal to any of the plurality of storage areas (251, 252). The data control unit (210) includes: a cam switch block which acquires a reference signal generated from an input signal input from a second apparatus (60) and compares a value of the reference signal and the condition values; and a logger block which switches, on the basis of the comparison by the cam switch block, the storage areas (251, 252) to which the digital value is written, and writes the digital value.
