If you have just received the Schneider 140 NOE 771 xx module but have not yet programmed it with an Ethernet configurable extension, you will need to assign an IP address to your module. In this guide you’ll receive information about assigning a 140 NOE Module Ethernet Address Parameter.
Using the BOOTP Lite software utility you can assign IP address parameters. One thing to note, however, is that with the modules 140 NOE 771 01, -11, and NWM 100 00 you can assign the IP address using web pages.

Using a BOOTP Server

BOOTP server is an application which manages your network device’s assigned IP addresses. Using your system administrator allows you to confirm whether a BOOTP server exists on your network and helps you use the server to maintain the adapter’s IP Address.

How an Unconfigured Module Obtains an IP Address

When your module first starts up without an IP Address, it will try to obtain an IP address from the network’s BOOTP server. When a response from a BOOTP server is made, the IP address in the response is used. If no response is received in two minutes, the module uses the default IP Address from its MAC address.

Connecting to the Default IP Address

You will need to set up an active route from your PC to connect to the default IP address with your PC. Use the following instructions to do this with Windows 95/98/ME/NT/2000 or Windows XP.

NOE 771 xx Duplicate IP Address Test

Once it receives an IP address, the module will test for duplicate addresses by sending broadcast ARP requests three times at 5-second intervals. The module will stay offline to avoid a network disruption if a duplicate IP address is found. If a duplicate IP address is found, the module will display a pattern of four flashes.
