DNP DEVICE PROFILE
210
DNP Channel Address
Range: 0 to 65519 in steps of 1
Default: 1
This setting specifies the DNP slave address. This number identifies the D90
communications link. Assign a unique address to each DNP slave.
DNP Client Address 1 through DNP Client Address 5
Range: any standard IP address
Default: 0.0.0.0
These settings force the D90
DNP TCP/UDP Port Number
Range: 1 to 65535 in steps of 1
Default: 20000
This setting specifies the TCP/UDP port to use for DNP communications.
DNP Unsolicited Response Function
Range: Enabled, Disabled
Default: Disabled
Program this setting to "Disabled" for RS485 applications, since there is no collision
avoidance mechanism.
DNP Unsolicited Response Timeout
Range: 0 to 60 seconds in steps of 1
Default: 5 seconds
This setting specifies how long the D90
unsolicited response.
DNP Unsolicited Response Maximum Re-Tries
Range: 1 to 255 in steps of 1
Default: 10
This setting specifies the number of times the D90
response without receiving confirmation from the master. A value of "255" allows infinite
re-tries.
DNP Unsolicited Response Destination Address
Range: 0 to 65519 in steps of 1
Default: 1
This setting specifies the DNP address to which all unsolicited responses are sent. The IP
address to which unsolicited responses are sent is determined by the D90
current TCP connection or the most recent UDP message.
DNP Current Scale Factor, DNP Voltage Scale Factor, DNP Power Scale Factor, DNP
Energy Scale Factor, DNP Other Scale Factor
Range: 0.001, 0.01, 0.1, 1, 10, 100, 1000, 10000, 100000
Default: 1
These settings scale the analog input current values. For example, if the DNP Current
Scale Factor is "10," all DNP analog input points that represent currents are returned
with values 10 times smaller (for example, a value of 700 amps on the D90
as 70). Likewise, if the DNP Voltage Scale Factor is "0.01," all DNP analog input points
that represent voltages are returned with values 100 times larger (for example, a value

of 17 volts on the D90
These settings are useful when analog input values must be adjusted to fit within certain
ranges in DNP masters.
