INFORMATION PROCESSING DEVICE, METHOD, AND PROGRAM

WIPO Patent Application WO/2022/185589

A1

The objective of the present invention is to set a communication cycle range that satisfies a synchronization accuracy, from a processing load of a control device and a network load. This information processing device: calculates a first communication cycle for each control device, from a surplus time based on a processing load for control-related processing in a pre-determined cycle, and a required time for performing time synchronization processing once; calculates a second communication cycle from a surplus bandwidth based on the network load and a bandwidth required to communicate one synchronization message; and calculates a range for a communication cycle for the synchronization message using the longer cycle from among both the longest cycle among the first communication cycles for each control device and the second communication cycle, and a communication cycle based on a predetermined synchronization accuracy.
