2.4 IP Addressing
Essential tasks of project configuration are assigning and controlling IP ad-
dresses and setting the individual Ethernet parameters. This way, the differ-
ent controllers and communication modules will be unambiguously
assigned within a group of several manufacturing systems.
Each network card in the computer and the controllers is provided with its
own IP address. It is 32 bit long and displayed in 4 group of figures that are
divided by dots. Each group lies within a range of 0 to 255.
Example: 121.2.64.229
To this address, a subnetwork mask will be assigned. For more information
regarding subnetwork masks, please refer to page 2–22.
An IP address is divided into a network address (Net-ID) and a node address
(Host-ID). The network address identifies the relevant subnetwork. The
node address serves for addressing a station within a subnetwork. This
subnetwork will be determined via the subnetwork mask, please refer to
page 2–22.
According to the size of the network, there are 5 address classes:
Class Description Address range
A 1 byte network address and
3 bytes node address 1.0.0.1 to
126.255.255.254
B 2 bytes network address and
2 bytes node address 128.0.0.1 to
191.255.255.254
C 2 bytes network address and
2 bytes node address 192.0.0.1 to
223.255.255.254
D Special addresses:

.
For addressing the communication modules, the IP addresses within
the address ranges of the classes A, B, and C are suitable.
.
Do not assign 0 or 255 as a node address (Host-ID), since 0 represents
the Net-ID and 255 represents the broadcast address of the correspon-
ding network.
