The B30 supports the Distributed Network Protocol (DNP) version 3.0. DNP is enabled when the

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 DNP Channels sub-menu is shown below.

for each channel. Once DNP is assigned to a serial port, DNP is the only protocol running on that port; Modbus or IEC
60870-5-103 are disabled. If DNP is assigned to RS485, the protocol must be set to DNP on the serial port configuration as
well, for the change to take effect. When the
DNP protocol can be used over TCP/IP on the Ethernet ports. When the
UDP," the channel 1 DNP protocol can be used over UDP/IP on the Ethernet ports. See the DNP appendix for information
on the DNP protocol.
Changes to these settings take effect when 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

those protocols.
The setting is the DNP slave address. This number identifies the B30 on a DNP communications link. Each

DNP slave should be assigned a unique address.
