NetLinx Integrated Controllers
Obtaining the Master’s IP Address (using DHCP)
1. Select Diagnostics > Network Addresses from the Main menu to access the Network
Addresses dialog.
2. Verify the System number corresponds to the value previously assigned in the Device
Addressing tab and verify that zero (0) is entered into the Device field.
3. Verify that NetLinx appears in the Host Name field.
4. Click the Use DHCP radio button from the IP Address section (FIG. 26).
5. Click the Get IP Information button to read the IP Address obtained by the on-board Master
from the DHCP Server and configure the unit for DHCP usage.
6. Note the obtained IP Address. This information is later entered into the Master
Communication Settings dialog and used by NetLinx Studio 2.2 (or higher) to communicate
to the Master via an IP. This address is reserved by the DHCP server and then given to the
Master.
7. Click the Set IP Information button to retain the IP Address from the DHCP server and assign
it to the on-board Master. A popup window then appears to notify you that Setting the IP
information was successful and it is recommended that the Master be rebooted.
Verify there is an active Ethernet connection attached to the rear of the NI-Series
Controller before beginning these procedures.
The system value must correspond to the Device Address entered in the Device
Addressing dialog. Refer to the Setting the System Value section on page 38 for
more detailed instructions on setting a system value.

DO NOT enter ANY IP information at this time; this step only gets the System Master
to recognize that it should begin using an obtained DHCP Address.
If the IP Address field is empty, give the Master a few minutes to negotiate a
DHCP Address with the DHCP Server, and try again. The DHCP Server can take
anywhere from a few seconds to a few minutes to provide the Master with an IP
Address.
