PROBLEM TO BE SOLVED: To provide a control controller and a data control method that are able to achieve all control processing within a constant control period without causing fluctuation in execution timing.SOLUTION: A control controller comprises: a communication unit that receives control object data from a control object apparatus, or outputs control result data for the control object data to the control object apparatus; a preprocessing unit that determines the number of registers used in ladder control processing on the basis of an execution period of the ladder control processing for the control object data received by the communication unit and a loop control period determined to be integer multiple of the period of the ladder control processing; control processing units that are provided according to the number of registers, and execute control processing for the control object data; and a calculation unit that has the respective control processing units execute at the loop control period at timing different from each other within the execution period, and outputs the execution results as control result data. |
