The B30 supports the Distributed Network Protocol (DNP) version 3.0. The B30 can be used as a DNP slave device con-
nected to multiple DNP masters (usually an RTU or a SCADA master station). Since the B30 maintains two sets of DNP
data change buffers and connection information, two DNP masters can actively communicate with the B30 at one time.
The IEC 60870-5-104 and DNP protocols cannot be simultaneously. When the IEC 60870-5-104 FUNCTION set-
ting is set to "Enabled", the DNP protocol will not be operational. When this setting is changed it will not become
NOTE
active until power to the relay has been cycled (off-to-on).

for each channel. Once DNP is assigned to a serial port, the Modbus protocol is disabled on that port. Note that COM1 can
be used only in non-Ethernet UR relays. When this setting is set to "Network - TCP", the DNP protocol can be used over
TCP/IP on channels 1 or 2. When this value is set to "Network - UDP", the DNP protocol can be used over UDP/IP on chan-
nel 1 only. Refer to Appendix E for additional information on the DNP protocol.
