4.2 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.

PROFINET supports the following topologies:

Line topology

[4-2] Line topology (M = I/O master, D = I/O device)

Star topology

[4-3] Star topology (M = I/O master, D = I/O device)

Tree topology

[4-4] Tree topology via switches (M = IO master, SW = switch, D = I/O device)
