The T60 supports the Distributed Network Protocol (DNP) version 3.0. The T60 can be used as a DNP slave device con-
nected to multiple DNP masters (usually an RTU or a SCADA master station). Since the T60 maintains two sets of DNP
data change buffers and connection information, two DNP masters can actively communicate with the T60 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 active until power to the relay has been cycled (off-to-on).
The DNP Channels sub-menu is shown below.

DNP CHANNELS
The
DNP CHANNEL 1 PORT
and
DNP CHANNEL 2 PORT
settings select the communications port assigned to the DNP protocol
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.
