Control device, control method, and program performing a tabulation operation at high speed

Abstract

A PLC, which is a control device includes a device memory that stores data acquired by an external sensor, a data extracting unit that periodically extracts data of predetermined types among the data stored in the device memory, a data distributing unit that stores the data extracted by the data extracting unit in an operation buffer corresponding to the data among a plurality of operation buffers provided according to the predetermined types, and a data tabulating unit that performs, when the operation buffer stores data equivalent to a predetermined period, arithmetic processing of the data stored in the operation buffer.
