3-6 Configure the 1734-AENT Adapter for Your EtherNet/IP Network
Set the Network Address
You can set the network Internet Protocol (IP) address 3 different ways:
1. Using the thumbwheel switches located on the module
2. Using a Dynamic Host Configuration Protocol (DHCP) server, such as
Rockwell Automation BootP/DHCP
3. Retrieving the IP address from nonvolatile memory.
The adapter reads the thumbwheel switches only at powerup to determine if
the switches are set to a valid number. Press either the + or - buttons to change
the number. Valid settings range from 001 to 254. When the switches are set to
a valid number, the adapter’s IP address will be 192.168.1.xxx (where xxx
represents the number set on the switches). The adapter’s subnet mask will be
255.255.255.0 and the gateway address is set to 0.0.0.0. The adapter will not
have a host name assigned, or use any Domain Name System when using the
thumbwheel settings.
If the switches are set to an invalid number (i.e. 000 or a value greater than
254), the adapter checks to see if DHCP is enabled. If DHCP is enabled, the
adapter requests an address from a DHCP server. The DHCP server will also
assign other Transport Control Protocol (TCP) parameters.
If DHCP is not enabled, the adapter will use the IP address (along with other
TCP configurable parameters) stored in nonvolatile memory. The factory
default switch setting is 999, and DHCP is enabled.
