Abstract

See full text

A communication system includes a master device, a slave device, and a relay device. The relay device includes a time synchronization management unit that stores retention time of a first time-synchronization frame sent from the master device, adds the first-time-synchronization-frame retention time to a correction field when a second time-synchronization frame sent from the master device is relayed, stores retention time of a third time-synchronization frame sent from the slave device, and adds the third-time-synchronization-frame retention time to a correction field when a fourth time-synchronization frame sent from the master device is relayed. The slave device includes a transmission delay time aggregation unit storing a value in the correction field of the second time-synchronization frame and characteristic information about priority in a frame in association with each other, and storing a value in the correction field of the fourth time-synchronization frame and the characteristic information in association with each other.
