3.7 UDP Application: Multi-Point Pair Connection
It is also possible to setup a pair connection in UDP mode to have more than one Pair
Connection Master or Slave to communicate with each other. For example, it is possible to
setup one Modbus Master and six Modbus Slaves in UDP,
. Note again that UDP
does not guarantee data delivery and only data would be transmitted over Ethernet; other
serial pings are not transmitted. If you use RS-232 along with flow control, it is
recommended to use Multi-Point Pair Connection in TCP,
Note: the Destination IP and Port for the Slaves need to be equal to the Master
’s IP and Port. Local Listening Port for
the Slaves needs to be equal to the Master
’s Destination Port.
