    7.2 FC Protocol Overview The FC protocol, also referred to as FC bus or Standard bus, is the Danfoss standard fieldbus. It defines an access technique according to the master-slave principle for communications via a serial bus. One master and a maximum of 126 slaves can be connected to the bus.
