PROFINET supports linear, tree or star structures. The bus or linear structure used in
the field buses is thus also available for Ethernet.
For transmission according to the 100Base-TX Fast Ethernet standard, network
cables and plug connectors in category STP CAT5 must be used (2 x 2 shielded
twisted pair copper wire cables). The cables are designed for bit rates of up to 100
Mbit/s. The transmission speed is automatically detected by the measuring system
and does not have to be set by means of a switch.
Addressing by switch is also not necessary, this is done automatically using the
addressing options of the PROFINET-Controller.
The cable length between two subscribers may be max. 100 m.
In case of IRT communication the topology is projected in a connection table.
Thereby you must pay attention on a right connection of the ports 1 and 2.
With RT communication this is not the case, it can be cabled freely.
