The tree structure combines the star and line structure:

• Repeaters divide the bus segments.
• Simple to locate a fault because only individual bus

segments are usually affected in the event of a fault.

• Connect M-Bus devices in star (1),

line (2) or tree structures (3).

• Each M-Bus device has its own address

within the bus structure.

• Divide (expand) bus structures into individual

bus segments with repeaters (line amplifiers).

• Up to 250 subscribers can be connected

together in a single bus segment (depending
on the M-Bus master).

• The bus structures ensure that the system

remains stable when M-Bus devices are
exchanged.

• The bus structure is out of operation during

a replacement of the M-Bus master.

The tree structure combines the star and line structure:

• Repeaters divide the bus segments.
• Simple to locate a fault because only individual bus

segments are usually affected in the event of a fault.

• Connect M-Bus devices in star (1),

line (2) or tree structures (3).

• Each M-Bus device has its own address

within the bus structure.

• Divide (expand) bus structures into individual

bus segments with repeaters (line amplifiers).

• Up to 250 subscribers can be connected

together in a single bus segment (depending
on the M-Bus master).

• The bus structures ensure that the system

remains stable when M-Bus devices are
exchanged.

• The bus structure is out of operation during

a replacement of the M-Bus master.

The tree structure combines the star and line structure:

• Repeaters divide the bus segments.
• Simple to locate a fault because only individual bus

segments are usually affected in the event of a fault.

• Connect M-Bus devices in star (1),

line (2) or tree structures (3).

• Each M-Bus device has its own address

within the bus structure.

• Divide (expand) bus structures into individual

bus segments with repeaters (line amplifiers).

• Up to 250 subscribers can be connected

together in a single bus segment (depending
on the M-Bus master).

• The bus structures ensure that the system

remains stable when M-Bus devices are
exchanged.

• The bus structure is out of operation during

a replacement of the M-Bus master.

The tree structure combines the star and line structure:

• Repeaters divide the bus segments.
• Simple to locate a fault because only individual bus

segments are usually affected in the event of a fault.

• Connect M-Bus devices in star (1),

line (2) or tree structures (3).

• Each M-Bus device has its own address

within the bus structure.

• Divide (expand) bus structures into individual

bus segments with repeaters (line amplifiers).

• Up to 250 subscribers can be connected

together in a single bus segment (depending
on the M-Bus master).

• The bus structures ensure that the system

remains stable when M-Bus devices are
exchanged.

• The bus structure is out of operation during

a replacement of the M-Bus master.
