PRODUCT SETUP
The
DNP TCP/UDP PORT NUMBER
takes effect when the F60 is restarted.
The
DNP UNSOL RESPONSE FUNCTION
mechanism. The
DNP UNSOL RESPONSE TIMEOUT
response. The
DNP UNSOL RESPONSE MAX RETRIES
unsolicited response without receiving confirmation from the master; a value of "255" allows infinite re-tries. The
UNSOL RESPONSE DEST ADDRESS
solicited responses are sent is determined by the F60 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 F60 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 are returned with values 1000 times smaller (for example, a value of 72000 V
on the F60 is returned as 72). These settings are useful when analog input values must be adjusted to fit within certain
ranges in DNP masters. Note that a scale factor of 0.1 is equivalent to a multiplier of 10 (that is, the value is 10 times larger).
The
DNP DEFAULT DEADBAND
settings group the F60 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
unsolicited responses from the F60 when any current values change by 15 A, the
is 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 F60, the default deadbands are 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.
The
DNP MESSAGE FRAGMENT SIZE
fragment sizes allow for more efficient throughput; smaller fragment sizes cause more application layer confirmations to
be necessary, which provides more robust data transfer over noisy communication channels.
Check the "DNP Points Lists" F60 web page to view the analog inputs and/or binary inputs points lists. This page
can be viewed with a web browser by entering the IP address of the F60 Ethernet port employed to access the F60
Main Menu, then by clicking the Device Information Menu item, then the DNP Points Lists item.
The
DNP OBJECT 1 DEFAULT VARIATION
number for object types 1, 2, 20, 21, 22, 23, 30, and 32. The default variation refers to the variation response when variation
0 is requested and/or in class 0, 1, 2, or 3 scans. See the DNP Implementation section in the UR Family Communications
Guide.
The DNP binary outputs typically map one-to-one to IED data points. That is, each DNP binary output controls a single
physical or virtual control point in an IED. In the F60 relay, DNP binary outputs are mapped to virtual inputs. However, some
legacy DNP implementations use a mapping of one DNP binary output to two physical or virtual control points to support
the concept of trip/close (for circuit breakers) or raise/lower (for tap changers) using a single control point. That is, the DNP
master can operate a single point for both trip and close, or raise and lower, operations. The F60 can be configured to
support paired control points, with each paired control point operating two virtual inputs. The
setting allows configuration of 0 to 32 binary output paired controls. Points not configured as paired
CONTROL POINTS
operate on a one-to-one basis.
The
DNP TCP CONNECTION TIMEOUT
there is no data traffic on a DNP TCP connection for greater than the time specified by this setting, the connection is
aborted by the F60. This frees up the connection to be re-used by a client. Any change takes effect after cycling power to
the relay.
