Appendix – Ethernet IP interface
The Cygnus Web Tension Control, with Ethernet IP, is designed to connect to a 10/100Mbit Ethernet network using
standard CAT5 cabling. Also, you should read the
Design Appendix Ethernet/IP
from the HMS website.

Configuring the IP address
CAUTION: If you are placing the Cygnus on a public or corporate network, please consult your IT
department or the person(s) responsible for your network, before connecting the Cygnus. Your IT
department is usually responsible for assigning or controlling IP addresses.
1) Set all the configuration switches on the Ethernet daughter card to OFF.
2) Turn on the power.
3) On the Cygnus, select
More… / Program / Configure I/O / Fieldbus
.
a) Make sure that the fieldbus board is
HMS
and that the fieldbus type is
Ethernet IP+WEB
.
b) Press any of the three keys on the lower right or left side of the display. This will display the network
configuration for the Cygnus.
c) Record the IP address, subnet mask, gateway address, and MAC address.
4) Connect the Cygnus to a 10/100Mbit Ethernet network, using a CAT5 cable.
5)
Open a DOS command prompt on a PC running Windows NT/2000/XP.
6)
In the DOS window type:
arp –s <IP-address> <MAC-address>
a) Substitute the desired IP address into the above command in place of
<IP-address>.
b) Substitute the MAC address from the Cygnus screen with the dashes in place of
<MAC-address>
. The
MAC address is also located on the bottom of the Ethernet IP daughter board.
7)
In the DOS window type:
ping <IP-address>
a) You should get a reply from the Cygnus
b) If there is no replay, repeat the ping.
c) If there is no reply after a second, repeat the above step after verifying the MAC address and IP address.
8)
In the DOS window type:
arp –d <IP-address>
a) The Cygnus will now adopt the new IP address.
b) You may have to cycle the power to display the new IP address.
9) Open Internet Explorer or another internet browser window with the following URL:
http://xxx.xxx.xxx.xxx/
where xxx.xxx.xxx.xxx is your new IP address.
10) The resulting web page will allow you to configure the subnet mask and gateway address for your particular
network. At this point, you could enable the Cygnus to use a DHCP server to dynamically configure the
Cygnus network settings. An example of that web page is shown below.
