Function Figure
You will need approved BusAdapters to connect a CFU to PROFINET IO. The BusA‐
dapters give you flexibility in selection of the connection technology for PROFINET IO.
The figure shows some typical device implementations of the BusAdapter.
There are BusAdapters for pre-fabricated specific bus cables and BusAdapters for
special media (fiber-optic cable, electrically conductive cables).
Approved BusAdapter versions for connecting a CFU to PROFINET IO are listed in
section "Article numbers (accessories / spare parts) (Page 181)".
