Abstract
Provided is a control device that includes a plurality of communication units that receive data from measurement control devices; a control unit that calculates an operation signal for controlling a controlled device on the basis of the data from the communication units and that outputs the operation signal to the controlled device; a storage unit that stores the data; a first monitoring unit and a second monitoring unit that perform a calculation on the basis of the data to calculate a calculation value, that determine whether the calculation value satisfies a blocking condition, and that output a blocking signal when the calculation value satisfies the blocking condition; and a first blocking unit and a second blocking unit that block the operation signal to the controlled device upon receiving the blocking signal output from at least either one of the first monitoring unit and the second monitoring unit.
