Chapter 2 Connect to the Controller
When the controller is in the out-of-the-box state, the following apply
regarding IP addresses:
• The Ethernet ports are DHCP-enabled. That is, the Ethernet ports are
configured to obtain an IP address via a DHCP server.
If there is no DHCP server or the DHCP server is not configured to set
the IP address, you must set the IP address manually.
• The controller is configured so that you must set the IP address on every
Ethernet port each time that power is cycled.
You can configure your controller so that you are not required to set an
IP address each time that power is cycled.
• The controller is configured to use Dual-IP mode. As a result, you must
set a unique IP address for port A1 and port A2.
You can use the following tools to set the IP address:
•BOOTP-DHCP tool
• DHCP server
• RSLinx Classic software
• Logix Designer application
•SD card
To operate on an EtherNet/IP network, you must define the following
parameters.
EtherNet/IP Network Parameter Description
IP address The IP address uniquely identifies the module. The IP address is in the form xxx.xxx.xxx.xxx where each xxx is a number from
000…255.
There are some reserved values that you cannot use as the first octet in the address. The following numbers are examples of
values you cannot use:
• 001.xxx.xxx.xxx
• 127.xxx.xxx.xxx
• 223 to 255.xxx.xxx.xxx
The specific reserved values that cannot be used vary according to the conditions of each application. The previous values are only
examples of reserved values.
Subnet mask The subnet mask divides IP addresses into a network address and a host address. It defines whether the controller exchanges
Ethernet packets directly with another device, or whether it routes packets through the Gateway. This field is set to 0.0.0.0 by
default.
Gateway A gateway connects individual physical networks into a system of networks. When a node communicates with a node on another
network, a gateway transfers the data between the two networks. This field is set to 0.0.0.0 by default.
