Abstract
A device and an initializing method for use in a ring communication path, which can highly accurately synchronize time of the master and slave stations so as to achieve accurate communication among those stations. According to this device and method in which timers of respective slave stations connected to a ring communication path are synchronized using a specific communication frame, a master station recognizes the number of slave stations and their connection sequences, and notifies each of the slave stations of an individual communication delay time. Respective slave stations correct their timers so as to agree to that of the master station.
