4-16 ENI Configuration (Node 248 to 254)
Node 254 - Ethernet Hardware Address
You will find the hardware address on a label affixed to the ENI as
shown to the left. The hardware address can also be read from node
address 254.
Table 4.7 ENI Baud Rate Options
Configuration Value (Integer) Baud Rate
0x0000 Autobaud Enabled
0x0001 1200
0x0002 2400
0x0003 4800
0x0004 9600
0x0005 19.2K
0x0006
38.4K
(1)
(1) All CompactLogix devices must be configured to use two stop bits when communicating with the ENI at 38.4K.
0x0007
57.6K
(1)
8 to 65535 Autobaud Enabled
IMPORTANT
The ENI cannot Autobaud to 57.6K to synchronize to
the attached controller. You must manually set the
baud rate to 57.6K. If the controller’s baud rate is
from 1200 to 38.4K, and the ENI is configured for
Autobaud, the ENI will synchronize with the
controller’s baud rate.
Autodetect of CRC/BCC occurs when autobaud is
selected. CRC is used when a fixed baud rate is
selected.
