CHAPTER 5: SETTINGS
The N60 supports the Distributed Network Protocol (DNP) version 3.0. DNP is enabled when the
 COMMUNICATIONS  PROTOCOL
multiple DNP masters (usually an RTU or a SCADA master station). Since the N60 maintains two sets of DNP data change
buffers and connection information, two DNP masters can actively communicate with the N60 at one time.
See the UR Series Communications Guide for more information on DNP.
The DNP Channels sub-menu is shown.

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
protocol can be used over TCP/IP on the Ethernet ports. When this value is set to "Network - UDP," the DNP protocol can be
used over UDP/IP on channel 1 only.
Changes to these port 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.
NOTE
The setting is the DNP slave address. This number identifies the N60 on a DNP communications link. Assign a
DNP ADDRESS
unique address to each DNP slave.
The N60 can specify a maximum of five clients for its DNP connections. These are IP addresses for the controllers to which
the N60 can connect. The settings follow.
