5.2 PRODUCT SETUP
5
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 used simultaneously. When the IEC 60870-5-104 FUNCTION
setting is set to "Enabled," the DNP protocol is not operational. When this setting is changed it does not become
active until power to the relay has been cycled (off-to-on).
NOTE
The DNP Channels sub-menu is shown below.

 DNP CHANNELS
The
DNP CHANNEL 1 PORT
for each channel. Once DNP is assigned to a serial port, the Modbus protocol is disabled on that port. 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 channel 1 only. Refer to Appendix E for additional information on the
DNP protocol.
Changes to these settings take effect only after power has been cycled to the relay.
Do not set more than one protocol to the same TCP/UDP port number, as this results in unreliable operation of
NOTE
those protocols.
