Manual VIPA CPU 21x Chapter 4 Deployment of the CPU 21x-2BT10 with TCP/IP
HB103E - Rev. 05/45 4-31
After you configured all connections this way, you may save and compile
your project and exit NetPro.
To store the CP project engineering data in the system data, you have to
activate the option "Store project data in the CPU" (default setting) at
object properties area Options in the hardware configuration of the CP.
The expression "connection" is also used at UDP although there is no
explicit connection establishment between the communication partners
during runtime of the stations.
But during the project engineering like at with e.g. TCP the communication
partners are assigned to each other and therefore logical linked-up.
Only at UDP the following options are additionally available at the selection
of the connection partner:
• All broadcast stations
• All multicast stations
By selecting All broadcast stations as connection partner, you define that
UDP telegrams are to be send to all available broadcast participants.
Please regard that the CP may exclusively receive broadcast telegrams.
The reception of user data via broadcast is not possible. 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 engi-
neering 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 send 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 a valid multicast group address as partner IP during project
engineering of a multicast connection. Additionally to this address you
have to set a common port for sender and receiver.
