Set the Network
Parameters Three rotary encoder switches on the front of the module enable you to set the
operating mode for using or maintaining network parameters such as IP address,
subnet mask, and gateway address. You can assign a static IP address to the
module by using the rotary switches to set the last octet.
The module ships with the rotary switches set to 999 and DHCP enabled. To
change the network address, you can do one of the following:
• adjust the rotary switches on the front of the module.
• use a Dynamic Host Configuration Protocol (DHCP) server, such as
Rockwell Automation BootP/DHCP.
• retrieve the IP address from nonvolatile memory.
The module reads the rotary switches first to determine if the switches are set to a
valid number. To set the network address:
1.
Remove power.
2.
Rotate the three switches on the front of the module using a small blade
screwdriver.
3.
Line up the small notch on the switch with the number setting you wish to
use. Valid settings range from 001…254.
4.
Reapply power.
Alternatively, you can reset the rotary switches and use BOOTP or DHCP to
obtain the network parameters for the module. If you change the operating mode
or network parameters during operation, you must cycle power to the module for
the changes to take effect.
The following table lists the possible rotary switch settings for the module:
IMPORTANT A static IP address is required to use the QuickConnect feature.

Value Function
001…254 This value is used as the last octet of the IP address. For example, if the switches are set to
010, the IP address of the module is 192.168.1.10.
The factory setting for the subnet mask is 255.255.255.000 and the gateway address is
192.168.1.1.
If you set the switches to 001, the gateway address is changed to 0.0.0.0.
000 (Default),
255…999 (Except 888) If the switches are set to an invalid number (for example, 000 or a value greater than 254,
excluding 888), the module checks if DHCP is enabled.
• If DHCP is enabled, the module asks for an IP address from the DHCP server.
• If DHCP is not enabled, the module uses the IP address (along with other TCP
configurable parameters) that is stored in nonvolatile memory.
888 The module performs a reset to factory settings. The network parameters are also reset to
default values. Communication with the module is disabled.
