3.1.5 Topology
The PROFINET module features a built-in Ethernet-switch, thus having two Ethernet RJ-45 connectors. This enables the
possibility for connecting several PROFINET options in a line topology as an alternative to the typical star-topology.
The two ports are equal, in the sense that they are transparent for the option. If only one connector is used, both ports can
be used.
