You can disconnect remote units from the bus and replace them without disturbing other units or
their communication with Advant Controller 450. Communication with a reconnected unit is
resumed automatically.
MasterFieldbus operates at 2 Mbits/s.
For distances up to 25 m (82 ft.), use MasterFieldbus with twisted pair cable and without
modems. For longer distances, use modems. Both coaxial and optical types of cable are
available.
MasterFieldbus can also operate at 375 kbits/s. This speed is used, for example,
when communicating with MasterPiece 90.
For increased availability, you can duplicate the cables and modems (physical redundancy).
gives an example of a physical configuration.
