 DNP CHANNELS

The
DNP CHANNEL 1 PORT
for each channel. Once DNP is assigned to a serial port, the Modbus protocol is disabled on that port. 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 on channel 1 only. Refer to Appendix E for additional information on the
DNP protocol.
Changes to the DNP CHANNEL 1 PORT and DNP CHANNEL 2 PORT settings take effect only after power has
been cycled to the relay.

The
DNP UNSOL RESPONSE FUNCTION
mechanism. The
DNP UNSOL RESPONSE TIMEOUT
response. The
DNP UNSOL RESPONSE MAX RETRIES
ited response without receiving confirmation from the master; a value of "255" allows infinite re-tries. The
RESPONSE DEST ADDRESS
ited responses are sent is determined by the D60 from the current TCP connection or the most recent UDP message.
The DNP scale factor settings are numbers used to scale analog input point values. These settings group the D60 analog
input data into the following types: current, voltage, power, energy, power factor, and other. Each setting represents the
scale factor for all analog input points of that type. For example, if the
all DNP analog input points that are voltages will be returned with values 1000 times smaller (for example, a value of 72000
V on the D60 will be returned as 72). These settings are useful when analog input values must be adjusted to fit within cer-
tain ranges in DNP masters. Note that a scale factor of 0.1 is equivalent to a multiplier of 10 (that is, the value will be 10
times larger).
The
DNP DEFAULT DEADBAND
settings group the D60 analog input data into the following types: current, voltage, power, energy, power factor, and other.
Each setting represents the default deadband value for all analog input points of that type. For example, to trigger unsolic-
ited responses from the D60 when any current values change by 15 A, the
should be set to "15". Note that these settings are the deadband default values. DNP object 34 points can be used to
change deadband values, from the default, for each individual DNP analog input point. Whenever power is removed and
re-applied to the D60, the default deadbands will be in effect.
The
DNP TIME SYNC IIN PERIOD
Changing this time allows the DNP master to send time synchronization commands more or less often, as required.
