• InterBus option is certified by the
Frauenhofer Institute
The Gateway IB-S/DP for Danfoss variable frequency
drives allows for up to 14 variable frequency drives of
different series on the same InterBus network
FC Protocol
An RS-485 interface is standard on all Danfoss
variable frequency drives allowing for up to 126 units
in one network. The FC protocol has a very simple
design described in Serial Communication. For
applications where data transmission speed is of less
importance, the RS 485 interface provides a good
alternative to the faster fieldbus solution.
The FC protocol can also be used as a service bus
for transfer of status information and parameter
setup. In this case it is combined with normal time
critical I/0 control via digital inputs.
