Connecting CompactLogix Controllers on Ethernet 8-11
The 7 rungs used to configure ENI #2 are defined as follows:
The following table contains the information needed to send
messages to the ENI/ENIW to configure it for this example. For a
complete list of ENI/ENIW configurable features, please refer to
Chapters 4 and 5.
Table 8.3 ENI #2 Configuration - Rung Descriptions
Rung Function
2 This rung initiates the process and configures the ENI/ENIW module’s Serial port
for bridge mode at 38400 Baud.
3 This rung is initiated by the Done bit of the previous MSG and it disables BOOTP.
4 This rung configures the ENI/ENIW with its own IP address.
5 This rung adds the IP address of the SLC 5/05 controller to the ENI/ENIW
module’s Message Routing table at DF1 node 1. This means that any message
sent by the CompactLogix controller with a DF1 destination address of 1, will be
sent to the SLC 5/05 controller on Ethernet.
6 This rung adds the IP address of the 1756-ENBT module to the ENI/ENIW
module’s Message Routing table at DF1 node 45. This means that any message
sent by the CompactLogix controller with a DF1 destination address of 45, will be
sent to the 5550 controller in slot 0, via the 1756-ENBT module on Ethernet.
7 This rung adds an email address to the ENI/ENIW module’s email routing table at
DF1 node 50. This means that any email message sent by the CompactLogix
controller with a DF1 destination address of 50 will be sent to this email address.
8 This rung instructs the ENI/ENIW module to save the configuration data sent to it
in non-volatile memory.

248 Save/Reset Integer N/A 2 0 = save configuration to flash
250 TCP/IP Config. Integer N/A 8 Assign an IP Address to the
ENI/ENIW
252 BOOTP Integer N/A 2 1 = disable BOOTP/DHCP
253 Baud Rate Integer N/A 2 106 = bridge mode at 38400 Baud
(1) First integer must contain the number of characters (45 maximum) in the email address. The second integer contains the first two ASCII characters of the email address.
The third integer contains the next two ASCII characters, and so on, until the complete email address has been entered. All remaining integers in the integer array must be
zero.
(2) For ENI/ENIW series B FRN 2.20 or higher, you may use a string variable of length 5 bytes (for 1 character) to 49 bytes (for 45 characters). The first 4 bytes of a
CompactLogix string element contains the number of characters in the string (1 to 45).
