8-2 Connecting CompactLogix Controllers on Ethernet
System Diagram Figure 8.1 Example ENI/ENIW Network
The computer must include the following software:
• RSLogix5000
• RSLinx, version 2.31.00 or later
• RSLogix500
• ENI/ENIW Configuration Utility
The Ethernet Interface Card in the computer is used to connect
directly to the SLC 5/05 controller (channel 1), to the ControlLogix
controller via the 1756-ENBT card, and to the CompactLogix controller
via a series B/C/D ENI/ENIW. Alternatively, the computer’s COMM
Port can be used to connect to the CompactLogix controller via two
ENI/ENIW modules.

IMPORTANT
If the CompactLogix controller is connected to a ENI
series A, then you must connect a second ENI/ENIW
to your PC’s RS-232 port (as shown in the example
network on page 8-2) in order to go online with it
using RSLogix 5000. If the CompactLogix controller is
connected via a ENI/ENIW series B/C/D, then you
may go online with it using RSLogix 5000 through
the PC’s Ethernet card.
