3.3.16. 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 3.34). Note again that UDP does not guarantee data delivery and only data would be transmitted
over Ethernet; other serial pings are not transmitted. If RS-232 along with flow control, it is recommended to
use Multi-Point Pair Connection in TCP (section
).
Note that 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 needs to be equal to the Master
’s Destination Port.
