Address Management for Ethernet Modules

Introduction

CAUTION

UNINTENDED EQUIPMENT OPERATION

You must carefully manage the modules’ IP addresses because each device on the network requires a unique address. If two devices have duplicate network addresses, you can not predict the operation of the equipment.

Failure to follow these instructions can result in injury or equipment damage.

NOTE: Consult your system administrator to obtain the appropriate network address and subnetwork mask.

MAC Address

The is unique to each Ethernet module. It is defined in the factory by the module manufacturer.

NOTE: Given the risk of duplicate addresses, ensure that the address conforms to the manufacturer’s addressing scheme.

IP Address

General case: Define this address when configuring the module. This address must be unique.

Exception: In the absence of configuration by Control Expert, the server, etc., the default IP address of the BMX NOE 01x0 and the Ethernet port of the BMX P34 20x0 CPUs is derived from the MAC address.
