CHAPTER 4: DNP 3 DNP COMMUNICATION
869 MOTOR PROTECTION SYSTEM – COMMUNICATIONS GUIDE 4-3
The following setpoints are in the PATH: SETPOINTS > DEVICE > COMMUNICATIONS > DNP
PROTOCOL
DNP CHANNEL 1 PORT
Range: NONE, NETWORK - TCP, NETWORK- UDP
Default: NONE
DNP CHANNEL 2 PORT
Range: NONE, NETWORK - TCP, NETWORK- UDP
Default: NONE
The DNP Channel 1 Port and DNP Channel 2 Port settings select the communications
port assigned to the DNP protocol for each channel. 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.
FAST PATH:
If the additional communication module is not present, only RS485 is a possible option. The
Network options are hidden in this case and the DNP channel is assigned to the RS485 port
by default.
DNP ADDRESS
Range: 0 to 65519 in steps of 1
Default: 65519
Sets the DNP slave address. This number identifies this 869 on a DNP communications
link. Each DNP slave should be assigned a unique address.
DNP NETWORK CLIENT ADDRESS 1(2)
Range: Standard IP Address
Default: 0.0.0.0
The DNP Network Client Address settings can force the 869 to respond to a maximum of
two specific DNP masters.
DNP TCP/UDP PORT NUMBER 1 (2)
Range: 1 to 65535 in steps of 1
Default: 20000
The DNP NETWORK CLIENT ADDRESS 1(2) and DNP TCP/UDP PORT NUMBER 1(2) settings
are available only if the communications card is present. “DNP Channel 1 Port” takes the
“Port Number 1” and “Client Address 1” to allow or reject connections. The same relation
is used by channel 2.
