DEVICE
DNP Protocol
NOTE:
4–36
Behavior: One static network route was added to the destination 10.1.3.0/24, where a
laptop running EnerVista is located. This static route uses a different gateway (10.1.2.1)
than the default route. This gateway is the address of Router 2, which is "aware" of
destination 10.1.3.0 and is able to route packets coming from the 8 Series device and
destined to EnerVista.
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.
