There are several topologies available for both redundant and non-redundant PROFIBUS networks:

• Point-to-point – A single cable from master to slave.
• Daisy chain – A single cable daisy chained in and out of each field unit device. End of segment

devices only have one incoming cable.

• Tree – Cables and electronic devices (such as repeaters or link modules) are used to branch out

from different points.

• Ring – Often implemented with fiber-optic cable which forms a circle or ring when used with

Optical Link Modules. This topology yields redundancy so that any single component fault or cable
break does not affect the network (except for the component).

• Combination of the above.
NOTE: Bus with Spurs, also referred to as stub lines, are not recommended by PROFIBUS as they can
create parallel resistance and cause disturbances and reflections on the main trunk or bus line.
