摘要

Provided is an information processing device constituting at least a part of a communication system. The information processing device includes a master unit connected to a first communication line, and at least one slave unit connected to the master unit via a second communication line. The master unit includes: a first communication unit for transmitting/receiving data with another device via the first communication line in every predetermined cycle; a second communication unit for transmitting/receiving data with the slave unit via the second communication line in a time period shorter than the cycle; and an update unit for, after preceding data is received via the first communication line, updating data with the slave unit via the second communication line before arrival of subsequent data corresponding to the next cycle.
