Network - GE AF-650 GP Operating Instructions Manual

NB!
Please observe that mounting drives of different power-sizes in a line topology may result in unwanted power-off behaviour.
Smaller drives discharge faster than bigger drives. This can result in loss of link in the line topology, which may lead to control word timeout.
To avoid this, mount the drives with the longest discharge time first in the line topology.
Illustration 3.4: Ring/redundant line topology
NB!
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.

3.1.5 Network

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 envi-
ronments 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.
For more information regarding IP-switching, please refer to section: IP Traffic in this manual.
