Assigning Ethernet Address Parameters on M1 Ethernet Processors

Overview As shipped from the factory, the M1 Ethernet processor does not contain an IP

address. This is also true if you have not programmed the unit with an Ethernet

configuration extension. In this condition, when the module starts up, it will attempt

to obtain an I’s BOOTP server.

You can use Concept to assign an IP address, default gateway and subnetwork

mask (see p. 293).

You can also assign IP address parameters using the BOOTP Lite software utility

(see p. 158).

Using a BOOTP

Server

A BOOTP server is a program which manages the IP addresses assigned to devices

on the network. Your system administrator can confirm whether a BOOTP server

exists on your network and can help you use the server to maintain the adapter’s IP

address.

How an

Unconsidered

Module Obtains

an IP Address

On startup, an unconfigured processor will attempt to obtain an IP address by

issuing BOOTP requests. When a response from a BOOTP server is obtained, that

IP address will be used.

Specifying

Address

Parameters

Consult your system administrator to obtain a valid IP address and appropriate

gateway and subnet mask, if required. Then follow the instructions on p. 293.

DUPLICATE ADDRESS HAZARD

Be sure that your processor adapter will receive a unique IP address. Having two

or more devices with the same IP address can cause unpredictable operation of

your network.

Failure to follow this instruction can result in injury or equipment damage.
