17 Network Configuration

17.1 Configuration for Static LAN

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].
