IP Address

General Each device on the network must have a unique IP address.

The unique nature of the IP address is ensured by the attribution of a "network ID"

by an approved body. The choice between the various classes depends on the

number of networks in the installation and the number of devices to be connected.

Address

Structure

Each IP address consists of two elements (network name and device identifier),

where network name identifies a network (or a site) and where device identifier

identifies a device connected to this network. There are three classes of IP address.

Address Classes The structure of the address classes is as follows:

Externally, a device's IP address is represented by a string of four 8-bit values (0 to

255), separated by dots: "a.b.c.d".

Default IP

Address of the

Ethernet

Interface for the

TSX ETG 1000

Module

The default IP address of the Ethernet interface for the TSX ETG 1000 module is

constructed from its MAC address:

085.016.xxx.yyy where xxx and yyy are the last two numbers of the MAC address.

Example:

The MAC address of the module (in hexadecimal format) is: 00 80 F4 01 12 20.

In this case the default IP address (in decimal format) is: 085.016.018.032.
