Configure the Redundant I/O System
Chapter 5
Add the 1715-AENTR Adapter
to the I/O Configuration Tree
Once the project, controller and Ethernet module are configured, you are
ready to add the 1715 adapter. In this section, you do the following:
• Add the 1715-AENTR adapter module to the project.
• Configure the adapter for the EtherNet/IP Network.
Step 1: Configure the Adapter for the EtherNet/IP Network
Plan IP addresses by doing the following.:
• You need to use two IP addresses.
• You need to know the subnet mask for the Ethernet network the
redundant modules are to operate on.
Options for Setting the IP Addresses of 1715-AENTR Modules
You can set the IP address of the redundant AENTR modules in the adapter base
by using the following:
• A BOOTP/DHCP utility. A BOOTP/DHCP utility is provided with
the Logix Designer application out of the box. See
Address on the BOOTP/DHCP Server on page 111
.
• Module Configuration properties specified in RSLinx Classic software, if
the modules are already configured.
• Module Properties dialog box 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 listed above, see the EtherNet/IP Modules in
Logix5000 Control Systems User Manual, publicatio
for
more information.
Ethernet Network
We recommend that static IP addresses be assigned to EtherNet/IP modules in
Logix5000 control systems.
We recommend that you 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 Logix5000 Control Systems User Manual, publicatio
for
more information.
