摘要： PROBLEM TO BE SOLVED: To provide a control system and a memory control method for the control system which efficiently perform communication between an input-output device and a central control device, and enhance operation efficiency of a control speed and the like.SOLUTION: A control system comprises a central control device and a plurality of input-output devices performing data input/output to/from a control target. Each of the plurality of input-output devices comprises temporary storage means for temporarily storing data input/output to/from the control target. The plurality of input-output devices store configuration information indicating predetermined areas for performing input/output to/from the control target. The plurality of input-output devices read out data by selecting an area indicated by the configuration information to transmit the read data to the central control device, or receive data from the central control device to write the received data by selecting an area indicated by the configuration information.
