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 B30 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 B30 analog
input data into the following types: current, voltage, power, energy, power factor, and other. Each setting represents the
5
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 B30 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 B30 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 B30 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 B30, the default deadbands will be in effect.
The B30 relay does not support power metering. As such, the
settings are not applicable.

The
DNP TIME SYNC IIN PERIOD
Changing this time allows the DNP master to send time synchronization commands more or less often, as required.
The
DNP MESSAGE FRAGMENT SIZE
fragment sizes allow for more efficient throughput; smaller fragment sizes cause more application layer confirmations to be
necessary which can provide for more robust data transfer over noisy communication channels.
When the DNP data points (analog inputs and/or binary inputs) are configured for Ethernet-enabled relays, check
the "DNP Points Lists" B30 web page to view the points lists. This page can be viewed with a web browser by enter-
