For the project engineering of connections, open the connection list by
selecting the according CPU. Choose

A dialog window opens where you may choose the
connection partner and
the
connection type.
Each station configured in the Siemens SIMATIC manager is listed in the
table of connection partner. These stations are unique
specified by an IP
address and a subnet mask.
Here the connection partner may exist in the
current project or in an
unknown project. Connection jobs to an unknown project must be defined
by an unique connection name, which is to be used in the projects of both
stations.
Due to this allocation the connection remains
unspecified.
Exclusive at UDP connections you may send to every reachable
participant. The receipt of user data is not possible.
The broadcast participants are specified by one
port and one broadcast
address at sender and receiver.
Per default, broadcasts that are only serving the Ethernet communication,
like e.g. ARP-Requests (Search MAC <> IP address), are received and
accordingly processed. For the identification of the broadcast participants
within the net, you have to define a valid broadcast address as partner IP
during project engineering of a broadcast connection. Additionally to the
broadcast address you have to set a common port for sender and receiver.
By selecting
All Multicast stations you define that UDP telegrams have to
be sent res. received by all participants of a multicast group. In opposite to
broadcast here a reception is possible.
For the identification of the multicast participants within the net, you have to
define one
valid multicast group address and one port for sender and
receiver.
The maximum number of multicast circles, which are supported by the CP,
is identical to the maximum number of connections.
