IP subnet
Byte 1 / 2 / 3 / 4
0 … 255
Enter the subnet mask here. The device uses the values entered in this mask to
determine whether there is a communications partner in the local network. If there is
no partner in the local network, the device will not send the telegrams directly to the
partner but to the gateway that routes the telegram.
IP gateway address
Byte 1 / 2 / 3 / 4
0 … 255
Enter the IP address of the gateway here.
Note: If the KNX PS640-IP will only be used in the local LAN, the entry of 0.0.0.0 can
remain unchanged.
Example of assigning IP addresses
A PC is to be used to access the KNX PS640-IP.
IP address of the PC:
192.168.1.30
Subnet of the PC:
255.255.255.0
The KNX PS640-IP is located in the same local LAN, i. e. it uses the same subnet. The
subnet constrains the IP addresses that can be assigned. In this example, the IP address
of the KNX PS640-IP must be 192.168.1.xx, where xx can be a number from 1 to 254
(with the exception of 30, which is already in use). It must be ensured that no numbers
are assigned twice.
IP address of the KNX PS640-IP:
192.168.1.31
Subnet of the KNX PS640-IP:
255.255.255.0
