METHOD FOR TIME SYNCHRONIZATION IN AN ETHERNET-BASED NETWORK

摘要

The invention relates to a method for time synchronization in an Ethernet-based network, which has at least one master network subscriber and one slave network subscriber, which method comprises steps for the sending out of a first telegram by the master network subscriber, the slave network subscriber receiving the first telegram at a first reception time value of a local system time of the slave network subscriber and storing the first receiving time value; for the reading out of the first reception time value by the master network; for the sending out of a second telegram by the master network subscriber, the slave network subscriber receiving the second telegram at a second reception time value of the local system time of the slave network subscriber and storing the second reception time value; for the reading out of the second reception time value by the master network subscriber; for the calculation of a speed parameter of the local system time of the slave network subscriber from the reception time values by the master network subscriber; and for the transfer of the speed parameter to the slave network subscriber.
