Addresses Tab – Connection to all Multicast Nodes
By selecting “all multicast nodes” as the connection partner, you specify that
Ssent UDP frames are delivered to all multicast nodes of the multicast group;
Sthe local device receives multicast frames in the specified multicast group.
In the “Addresses” tab, a valid multicast address in the network is proposed for the
partner under the IP address (IP). When using multicast, the partner is always a
group of receivers (multicast group).
You must enter a PORT address suitable for all partners you want to reach under

IP addresses from 224.0.0.0 to 239.255.255.255 can be used for IP multicast.
Since the IP addresses up to 224.0.0.255 are reserved for special purposes, we
recommend that you use IP addresses starting at 224.0.1.0 (default) for IP
multicast.
