An Ethernet switch has a header device with a crossbar device and a number of downstream interface modules with a first number of a series of ports and a second number of a series of ports, respectively, such that in each case the same one in the series of the first number of ports is connected to a switching control unit coupled to an interface device, and the further ports in the series of the first number of ports are connected to a port in the second number of the series of ports via respective data lines routed in cascade form.

No-addressing modular-assembly Ethernet switch with a G.Link

The invention realizes high speed data transmission, as known from the Fast Ethernet, with fieldbus systems in the field of industrial automation. A suitable fieldbus component includes a data link layer, which operates with a fieldbus protocol, and a physical layer, which is constituted for high speed data transmission. There are also provided an interface, which connects the data link layer and the physical layer, and a layer for matching the data link layer to the physical layer.
