It is of high importance that the media chosen for Ethernet data transmission are suitable. Usually CAT 5e and 6 cables are
recommended for industrial applications. Both types of cable are available as Unshielded Twisted Pair and Shielded Twisted
Pair. Generally shielded cables are recommended for use in industrial environments and with frequency converters.
A maximum cable-length of 100 m is allowed between switches.
Optical fibres can be used for gapping longer distances and providing galvanic isolation.
For connecting EtherNet/IP devices both hubs and switches can be used. It is, however, recommended always to use
suitable industrial graded Ethernet switches. Hubs should always be avoided, since they will lead to collisions. For more
information regarding IP-switching, please refer to section:
IP Traffic
in this manual.
