4.3) KNX Multicast Address
For KNXnet/IP the multicast address
“
224.0.23.12
”
is the defined address from KNX Association in conjunction with IANA.
Change this address only if it becomes necessary due to the existing network.
Make sure that during commissioning all KNX IP devices intended to communicate with each other via IP use the same
multicast address. After downloading a new multicast address a manual restart has to be executed.
