Key Notes :
➢
All KNX IP devices that are intended to communicate with each other via IP must have the same IP multicast
address.
➢
Multicast IP address 224.0.23.12 may need to be changed in respect of the network type and of the network
components´ settings.
➢
IGMP (Internet Group Management Protocol) is used for IP configuration to establish multicast group belonging.
➢
If the IP address is changed from the IP side it may happen that ETS does no longer recognize the device and
connection cannot be maintained (tunnelling uses IP addresses).
➢
It is recommended to trigger a restart and to change IP addresses only from TP side.
➢
If problems occur for IP address assignment please ask your network administrator.
➢
According to the topology, the Tunnelling addresses always have to be assigned in the range of subline addresses.
For more information about additional physical addresses for tunnelling please check the section 5.5.
➢
Programming devices of another line different to which the device used for (re)programming is connected the use
of a correct topology is mandatory.
