Industrial Ethernet networks – Basics
4.1
TCP/IP addressing and subnets
The address of the TCP/IP protocol is set using the following parameters:
•
MAC address
•
IP address
•
Subnet mask
•
Standard gateway
The addressing mechanisms and subdivision of the TCP/IP networks into subnets are
explained in this chapter to help you set the parameters correctly.
4.2
MAC address
The MAC (

MAC address is a globally unique 6‑byte value (48 bits) assigned to the Ethernet
device. The MAC address of Ethernet devices from SEW‑EURODRIVE is 00-0F-69-
xx-xx-xx.
4.3
IP address
The IP address is a 32-bit value that uniquely identifies a node in the network. An IP
address is represented by 4 decimal numbers separated by decimal points.
Each decimal number stands for 1 byte (8 bits) of the address and can also be repre-
sented using binary code:
Exemplary IP address: 192.168.10.4

The IP address comprises a network address and a node address.
The part of the IP address that denotes the network and the part that identifies the
node is determined by the network class and the subnet mask.
