Method for synchronizing time in an ethernet-based network

A method for synchronizing time in an Ethernet-based network,

• wherein the network comprises a master network subscriber, a first segment and a second segment,
• wherein each segment comprises at least one network subscriber, and
• wherein the second segment is connected to the first segment via a first network distributor arranged in the first segment;
• and
• wherein the method comprises the following steps:
• sending out a synchronization telegram addressed to the second segment by the master network subscriber, the synchronization telegram being of a first type, wherein the network subscribers are configured in such a way that they do not take the synchronization telegrams into account if these are of the first type;
• receiving the synchronization telegram by the first network distributor;
• converting the synchronization telegram into a second type by the first network distributor, wherein the network subscribers are configured in such a way that they take synchronization telegrams into account if these are of the 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 network subscriber of the second segment;
• adjusting a speed of a local system time of the network subscriber of the second segment by using the synchronization value.
