Abstract

The object of the invention is a module (1-6, 1-8, 1-10, 1- 12, 2-2 ... 2-16, 3-2) for an automation data transmission network, said module (1 -6, 1 -8, 1-10, 1-12, 2-2 ... 2-16, 3- 2) comprising an Ethernet switch (3-8). The invention is characterized in that the module comprises means (3-10, 3-12, 3-14) for receiving and transmitting a two-part time synchronization pulse in which the first and second part of the two-part time synchronization pulse jointly indicate time data so that the module (1-6, 1-8, 1-10, 1-12, 2-2 ... 2-16, 3-2) is adapted to receive time data from the first part and to convey the first part through the module's Ethernet switch (3-8), and the module (1-6, 1-8, 1-10, 1- 12, 2-2 ... 2-16, 3-2) is adapted to convey the second part past the module's Ethernet switch (3-8) and, in response to the second part, to synchronize itself with the time data indicated by the first part.
