NOTICE
Unauthorised Access to the Device Can Cause Damage or Malfunction.
• When connecting the device to a network, protect the network from unauthorised access.

IEC 62443, ISO/IEC 27001.
Use of switches and routers
The switch integrated in the bus node enables division of the network into several segments.
The network can be divided into additional segments with the use of additional switches and routers.
This makes it possible to structure the network and expand the network.
Regardless of the network structure, the expansion of a PROFINET segment must not exceed certain
connection lengths:
–
Copper connecting cable, Ethernet twisted pair cable, 22 AWG:
max. 100 m between network participants, PROFINET end-to-end link
–
Optical connecting cable, POF fibre-optic cable, max. 12.5 dB signal attenuation over the entire
connecting section:
max. 50 m PROFINET end-to-end link.
6.3 Ensuring the degree of protection
–
Use connection hardware with the required degree of protection.
–
Use cover caps to seal unused connections.
