RESPONSE DEST ADDRESS
ited 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 will be returned with values 1000 times smaller (for example, a value of 72000
V on the F60 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 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 unsolic-
ited responses from the F60 when any current values change by 15 A, the
be set to "15". Note that these settings are the deadband default values. DNP object 34 points can be used to change dead-
band values, from the default, for each individual DNP analog input point. Whenever power is removed and re-applied to
the F60, 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.
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" F60 web page to view the points lists. This page can be viewed with a web
browser by entering the F60 IP address to access the F60 "Main Menu", then by selecting the "Device Infor-
NOTE
mation Menu" > "DNP Points Lists" menu item.
The
DNP OBJECT 1(32) DEFAULT VARIATION
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. Refer to the DNP Implementation section in Appendix E for additional details.
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 sup-
port paired control points, with each paired control point operating two virtual inputs. The
setting allows configuration of from 0 to 32 binary output paired controls. Points not configured as paired operate on
