Fieldbus PCI-Card
Anybus IPconfig
The same IP address as example 1, but subnet mask 255.255.255.0. This gives the subnet part of
the address to 172.17.20 and the node part to 106. This node can only communicate with nodes
which have an IP address starting at 172.17.20.
Example 3:
It is easier to understand the IP address parts if looking at their binary representations:
172.17.20.106 is in hex 0xAC11146A, 255.255.0.0 is 0xFFFF0000. Logical OR between the IP
address and the subnet mask gives the subnet address, which is 172.17.0.0.
0xAC11146A
& 0xFFFF0000

0xAC110000
There is a deprecated default rule regarding the subnet mask selection. It simplifies the subnet mask
selection, but makes many people unaware of it’s existence. IP addresses starting at 1-127 is class A
addresses and have subnet mask 255.0.0.0. 128-191 is class B with 255.255.0.0, 192-223 is class C
with 255.255.255.0. IP addresses starting at 224 is class D addresses and reserved for multicast
traffic.

Anybus IPconfig
The Anybus IPconfiguration tool can be downloaded from the HMS website.
1.
Locate “Support”
2.
On the dropdown menu, select Anybus-S or Anybus-M depending on if you use a slave or
master module.
3.
Select the network type.
A specific site for the selected fieldbus appears. The IP based boards have a link to the Anybus
IPconfig utility program. On this page there is also other useful information, e.g. how to configure the
network, see Fig. 16
