Chapter 6          Configure the Redundant I/O System
• Module Configuration properties that are specified in RSLinx Classic 
software, if the modules are already configured.
• Module Properties dialog box that is accessed by using RSLogix 5000 
programming software or the Logix Designer application, if the modules 
are already configured.
If you are configuring your redundant EtherNet/IP modules by using any 
of the software options that are listed previously, see the EtherNet/IP 
Network Configuration User Manual, 
publication ENET-UM001
 for more information.
Ethernet Network
We recommend that static IP addresses be assigned to EtherNet/IP modules in 
Logix 5000 control systems.
We recommend that you do not use dynamic IP addresses because if a power 
outage or other network failure occurs, modules with dynamic IP addresses 
can be assigned new addresses when the failure is resolved. If the IP addresses 
of modules change, you could experience a loss of control or other serious 
complications with your system.
However, if you must use the DHCP feature, you can use the Stratix® 8000 
switch, which can be configured to provide the same IP address to any given 
port.
See EtherNet/IP Network Configuration User Manual, publication ENET-
UM001, for more information.
Step 2: Add the 1715-AENTR Adapter to the Project
1. In the Logix Designer project, right-click the Ethernet network icon in 
the I/O Configuration folder, and choose New Module.
The Select Module dialog box appears.
