Use of switches and routers
The switch integrated into the control block makes it possible
to distribute the network into several segments.
With the help of additional switches and routers, the network
can be divided into additional segments. Thus, it is possible
to structure the PROFINET network and implement greater
network expansions.
Irrespective of the network structure, the expansion of a
PROFINET segment for 100Base−TX must not exceed 100 m.
Switches and routers for Industrial Ethernet are available on
the market from various companies. There are many IP20,
IP65 or IP67 components.
Unmanaged Switches:
For small Ethernet solutions with a low network load or
minimal requirements for deterministics.
Managed switches:
Networks can also be diagnosed and controlled,
redundant paths recognised and communication
solutions segmented.
