5.2.8 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, Figure 5.16. 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.TCP Server Application: Multi-Point TCP Pair
Connections.
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.
