Abstract

A method for synchronizing time in an Ethernet-based network having a master network subscriber, a first segment and a second segment. Each segment has at least one network subscriber. The second segment is connected to the first segment by a first network distributor, arranged in the second segment. The method comprises steps for sending out a synchronization telegram addressed to the second segment by the master network subscriber, the synchronization telegram being of the first type; receiving the synchronization telegram by the first network distributor, for conversion into a second type; forwarding the synchronization telegram to a network distributor of the second segment, by the first network distributor; reading out a synchronization value stored in the synchronization telegram by the first network distributor of the second segment; and adjusting a speed of a local system time of the network distributor of the second segment, using the synchronization value.
