The F11 is the next generation of the popular Power Hub. Ideal for fieldbus device or system, demonstrations, bench-top calibrations  and test setups, the Power Hub is a mini fieldbus segment in a box, just add devices.
A typical use for the Power Hub is to configure, precommission, test, or calibrate Fieldbus devices. In this case, the Fieldbus device and host device (Emerson 375 or 475, National Instruments Fieldbus interface, etc.) are connected to the Power Hub. No other components are required to have a functioning Fieldbus segment.
