Configurable connections are connections for the communication between
PLC stations. The connections may be configured with the Siemens project
engineering tool NetPro.
The following table shows the combination option with the different
operating modes:

Connection partner are stations at the counter side.
Specified connection partner
Every station configured in the Siemens SIMATIC Manager is entered in
the list of connection partners. By setting an IP address and a subnet mask
these stations are uniquely specified.
Unspecified connection partner
You may also set an unspecified connection partner. Here the connection
partner may be within the recent project or within an unknown project.
Connection commands to an unknown project must be defined via an
unique connection name that has to be used in the projects of both
stations. Due to the assignment via a connection name, the connection
itself remains unspecified.
All broadcast participants
Only with UDP connections you may here send messages to all available
broadcast participants. The reception is not possible. The broadcast
participants are specified via one
port and one broadcast address at
sender and receiver.
All multicast participants
This setting allows you to send and receive multicast telegrams between
the multicast participants. By setting of one
port and one multicast group
for sender and receiver the multicast participants are specified.
