PROBLEM TO BE SOLVED: To provide a plant control device that improves data transmission efficiency more than before, and enables improvement in usage efficiency of a bus.SOLUTION: A plant control device comprises: a plurality of apparatus devices 2A to 2C that performs an input/output of control information of a plant apparatus; and a processor 1 that performs computation processing for controlling the plant apparatus. In a case where the plurality of apparatus devices 2A to 2C and the processor 1 operate at a preliminarily set fixed basic period T, when performing the data transfer between each of the devices 2A to 2C, the processor 1 comprises: a scheduled amount of data transfer collection unit 1C that includes individually and preliminarily collects a scheduled amount of data transfer in each of the devices 2A to 2C; and a data transfer time allocation unit 1D that individually allocates a data transfer time as to each of the devices 2A to 2C so as to fall within the basic period Tin accordance with the scheduled amount of data transfer for each of the devices 2A to 2C, which is collected in such a way. |
