Danfoss VLT PROFINET MCA 120 User Manual

3.1.5 Topology
The PROFINET module features a built-in Ethernet-switch, thus having 2 Ethernet RJ45/M12 connectors. This enables the
possibility for connecting several PROFINET options in a line topology as an alternative to the traditional star-topology.
The 2 ports are equal, in the sense that they are transparent for the option, and thus it is free to select which of the 2 ports
to be used.
