5 SETTINGS
The
DNP DEFAULT DEADBAND
settings group the T35 Analog Input data into types: current, voltage, power, energy, 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 T35
when any current values change by 15 A, the
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 T35, 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.
The
DNP BINARY INPUTS USER MAP
Binary Inputs list contains 928 points representing various binary states (contact inputs and outputs, virtual inputs and out-
puts, protection element states, etc.). If not all of these points are required in the DNP master, a custom Binary Inputs points
list can be created by selecting up to 58 blocks of 16 points. Each block represents 16 binary input points. Block 1 repre-
sents binary input points 0 to 15, block 2 represents binary input points 16 to 31, block 3 represents binary input points 32
to 47, etc. The minimum number of binary input points that can be selected is 16 (1 block). If all of the
settings are set to "Not Used", the standard list of 928 points will be in effect. The T35 will form the binary inputs points list
from the settings up to the first occurrence of a setting value of "Not Used".

When using the User Maps for DNP data points (analog inputs and/or binary inputs) for relays with ethernet
installed, check the "DNP Points Lists" T35 web page to ensure the desired points lists are created. This
NOTE web page can be viewed using a web browser by entering the T35 IP address to access the T35 "Main
Menu", then by selecting the "Device Information Menu" > "DNP Points Lists" menu item.
The
DNP OBJECT N DEFAULT VARIATION
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 T35 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 T35 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 16 binary output paired controls. Points not configured as paired operate on
