5.2.2 Network topology
It is typical of PROFINET to have a rather free topology the limiting factor of which is large message
latencies due to e.g. switches connected in series.
Internal switch latency
( 17)
The combination of a line and a stub is useful for system wiring.
PROFINET supports the following topologies:
•Switch / star
[5-4] Switch / star topology (S = switch, D = I/O device)
•Tree via switches
[5-5] Tree topology (C =I/O controller, S = switch)
•Switch / switch
[5-6] Switch/switch topology (S = switch)
