DEVICE

DNP Protocol

NOTE:
4–36
Path:
Setpoints > Device > Communications > DNP protocol
DNP Channel (1 or 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.
DNP Address
Range: 0 to 65519 in steps of 1
Default: 65519
The DNP address sets the DNP slave address. This number identifies the 869 on a DNP
communications link. Each DNP slave must be assigned a unique address.
DNP Client Address 1 (2)
Range: standard IP address
Default: 0.0.0.0
The DNP Client Address settings can force the 869 to respond to a maximum of two
specific DNP masters.
DNP TCP/UDP Port 1 (2)
Range: 1 to 65535 in steps of 1
Default: 2000
"DNP Channel 1 Port" will take the "DNP TCP/UDP Port 1" and "DNP Client Address 1" to
allow/reject connections. The same relation is used by channel 2.
DNP Unsol Resp Function
Range: Enabled, Disabled
Default: Disabled
This setting will take effect for Ethernet communication only if the main card is present
or a comms card is available in the device. This setting enables/disables the unsolicited
response functionality. It is disabled for RS485 applications since there is no collision
avoidance mechanism.
DNP Unsol Resp Timeout
Range: 0 to 60 s in steps of 1
Default: 5 s
Sets the time the 869 waits for a DNP master to confirm an unsolicited response.
Unsol Resp Max Retries
Range: 1 to 255 in steps of 1
Default: 10
Sets the number of times the 869 retransmits an unsolicited response without receiving
confirmation from the master; a value of "255" allows infinite re-tries.
DNP Unsol Resp Dest Addr
Range: 1 to 65519 in steps of 1
Default: 1
Sets the DNP address to which all unsolicited responses are sent. The IP address to
which unsolicited responses are sent is determined by the 869 from the current TCP
connection or the most recent UDP message.
