Note: For this type of topology it is crucial that the network switch supports Spanning Tree
Protocol (STP), and that STP is enabled.
For more information on Spanning Tree please refer to section IP traffic.
Network
It is of high importance that the medias 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.
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.
For more information regarding IP-switching, please refer to section: IP Traffic in this manual.
