D90 LINE DISTANCE PROTECTION SYSTEM – INSTRUCTION MANUAL
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, DNP Client Address 2,..., 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
retries.
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
Power Factor 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
is "10," all DNP analog input points that represent currents are returned with
Scale Factor
values 10 times smaller (for example, a value of 700 amps on the D90
70). Likewise, if the
DNP Voltage Scale Factor
represent voltages are returned with values 100 times larger (for example, a value of
Plus
17 volts on the D90 is returned as 1700).
These settings are useful when analog input values must be adjusted to fit within certain
ranges in DNP masters.
