摘要

A star topology network-based control system and a time synchronization method are provided. A star topology type network control system includes: a master; one or more slave; and a repeater forming a data transmission path by connecting the master, the one or more slave through cables for performing a data relay function for data transmitted from the master to pass each of the slaves and transmitted to the master in the order of the formed data transmission path. [Reference numerals] (110) Master; (120a) Slave #1; (120b) Slave #2; (120c) Slave #3; (120d) Slave #4; (AA,BB,CC,DD) Processing unit; (EE) PHY transmission unit; (FF) PHY reception unit
