4.2.8 UDP Application: Multi-Point Pair Connection

It is also possible to setup pair connection in UDP mode to have more than one Pair

Connection Master or Slave to communicate to each other. For example, it is possible to setup

one Modbus Master and six Modbus Slaves in UDP, Fig. 4. 16. Note again that UDP does not

guarantee data delivery and only data would be transmitted over Ethernet; other serial pings

are not transmited. If RS-232 along with flow control, it is recommended to use Multi-Point Pair

Connection in TCP, see Sec. 4.2.10.

Note: the destination IP and Port of the Slaves need to be equal to the Master’s IP and Port. Local Listening Port of

the Slaves need to be equal to the Master’s Destination Port, see Table for an example.
