Abstract

Disclosed are a communication system and a synchronization method for enabling synchronization of units included in the communication system in case of a communication line failure. In the communication system according to the present invention, all units are synchronized with the period of an ADSYNC outputted from a master unit when the ADSYNC, in which a data transmission preparation period and a data transmission period make a single cycle, is outputted from the master unit; slave units output a free-run ADSYNC when an ADSYNC is not outputted from the master unit; and, when a plurality of the slave units output free-run ADSYNCs, the slave units are synchronized with any one free-run ADSYNC from among the outputted free-run ADSYNCs.
