Abstract: In the conventional distributed control system, since each control device updates the data area at a timing when a control packet is received, in a case where there is a difference in communication delay between the control devices or in a case where the communication delay includes jitter, it is difficult to match the contents of data in all the control devices in a case of focusing on a certain moment during system operation. Therefore, depending on the start timing of a control application, the control application operates on the basis of different data between the control devices, thus limiting control performance improvement. Accordingly, time slots on the network are allocated according to the result of a calculation unit, and a cyclic memory synchronization update unit synchronizes the timing of reflecting data in the input/output and the cyclic memory and the timing of using data of a cyclic memory.

Abstract: An administrative terminal receives designation of generation target data and of a generation destination storage device and identifies data similar to the target data. The terminal calculates a first predicted time expected for transmitting the target data from a storage device holding the target data to the generation destination storage device, and a second predicted time expected to be required for a second transmission process of transmitting the similar data from an object storage service to the generation destination storage device and of transmitting difference data between the target data and the similar data from the storage device holding the target data to the generation destination storage device. If the second predicted time is shorter than the first predicted time, the administrative terminal performs the second transmission process to transmit the similar data and the difference data to the generation destination storage device to generate the generation target data therein.
