EtherNet/IP Network
Communication Rates
The CompactLogix 5480 controllers support the following EtherNet/IP
network communication rates:
• 10 Mbps
• 100 Mbps
• 1 Gbps
Network performance in a CompactLogix 5380 system is optimal if the 1-
Gbps network communication rate is used. However, many Ethernet devices
do not support the 1-Gbps network communication rate. Instead, they support
a maximum rate of 100 Mbps.
The difference in maximum network communication rates impacts your
CompactLogix 5480 system. In some applications, the difference restricts you
from using the 1-Gbps network communication rate on a CompactLogix 5480
controller.
When you design a CompactLogix 5480 system and consider using the 1-Gbps
network rate on the controller, remember the following:
• You can use the 1-Gbps network communication rate on the controller
ports when all network devices support the 1 Gbps, for example,
5069-AEN2TR adapters with Compact 5000™ I/O modules.
When you use the 1-Gbps network communication rate for all devices
on the network, configure the controller ports to use Auto-Negotiate.
