Rockwell Automation 1734-AENT POINT I/O EtherNet/IP Adapter Module - Manual (Page 36)

20 Configure the Adapter for Your EtherNet/IP Network
The adapter reads the thumbwheel switches only when you cycle power 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 (such as 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.
Use the Rockwell
BootP/DHCP Utility
The Rockwell Automation BootP/DHCP utility is a stand alone program that
incorporates the functionality of standard BootP software with a user friendly
graphical interface. It is located in the Utils directory on the RSLogix 5000
software installation CD. The 1734-AENT adapter must have DHCP enabled
(factory default and the network address switches set to an illegal value) to use
the utility.
To configure your adapter using the BootP utility, perform the following steps:
1. Run the BootP software.
In the BOOTP Request History panel you see the hardware addresses
of devices issuing BootP requests.
