mode while others can be configured (along with the Access Point) for
UDP mode.
In this configuration, the Host PC can use both data paths to reach the
RTUs. This may be helpful when a mixed collection of RTUs is present
where some RTUs can operate in a broadcast form while others cannot
(see Figure 2-41 on Page 76 and Table 2-4 on Page 76).
Operation and Data Flow
• Communicate with RTU A by Telneting to Remote 1, port 30011.
• Communicate with RTU B by Telneting to Remote 2, port 30011.
• Communicate with RTUs C and D by sending and receiving data
from the Access Point’s
COM
port.
• All communication paths can be used simultaneously.
