17.1.1 Configuring the Cluster Controller for Static LAN
Different IP address ranges required for Speedwire network and LAN
In order for an unambiguous assignment of the IP addresses in the Speedwire network and in
the LAN to be possible from the perspective of the Cluster Controller, the IP address ranges of
both networks must be different. By default, the Cluster Controller uses address range
172.22/16 (172.22.0.1 to 172.22.255.255) for the Speedwire network.
• Ensure that different IP address ranges are used for the Speedwire network and the LAN.
Observe the configuration of the router and the network switch
For the Speedwire connection, the product uses IP addresses from the Unicast range and also
IP addresses from the Multicast range 239/8 (239.0.0.0 to 239.255.255.255).
• When using a router or network switch, ensure that the router and the network switch
forward the Multicast telegrams required for the Speedwire connection to all nodes in the
Speedwire network (for further information on how to configure the router or network
switch, see the manual from the manufacturer).
Procedure:
1. Write down the previous IP address, subnet mask and gateway address of the computer.
2. Connect the computer to port
X13
or
X14
on the Cluster Controller.
3. Read off and write down the IP address of the Cluster Controller from the display:
• Select the display view
External communication
.
• Read off the IP address from the
IP address
line and write it down.
4. Adapt the network settings of the computer:
• Adapt the IP address.
Example: adapting the IP address of the computer to the address range of the
Cluster Controller
The IP address of the Cluster Controller is "169.254.0.3" and the IP address of the computer
is "10.4.33.105".
• Change the IP address of the computer to
169.254.0.4
.
• Change the subnet mask to
255.255.0.0
.
• Ensure that no gateway address is entered.
5. Call up the Cluster Controller via the IP address read off from the display and log in.
6. Select the Cluster Controller in the system tree and select the menu
Settings
in the device
menu.
7. Disable DHCP if it has not yet been disabled.
• Select the parameter group
External communication > Ethernet > DHCP
.
• Select [
Edit
].
