4 Installation / Preparation for Commissioning

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 100MBit/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 nodes may be max. 100 m.
For IRT communication the topology is configured in a connection table. Correct
connection of ports 1 and 2 must be ensured.
This is not the case for RT communication, which can be freely wired.
To ensure safe and fault-free operation, the
