5.2 PRODUCT SETUP
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 DEFAULT VARIATION
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. 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
POINTS
a one-to-one basis.
The setting is the DNP slave address. This number identifies the F60 on a DNP communications link. Each
DNP ADDRESS
DNP slave should be assigned a unique address.
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 will be
5
aborted by the F60. This frees up the connection to be re-used by a client.
Relay power must be re-cycled after changing the
effect.

DNP / IEC104
POINT LISTS
The binary and analog inputs points for the DNP protocol, or the MSP and MME points for IEC 60870-5-104 protocol, can
configured to a maximum of 256 points. The value for each point is user-programmable and can be configured by assigning
FlexLogic™ operands for binary inputs / MSP points or FlexAnalog parameters for analog inputs / MME points.
The menu for the binary input points (DNP) or MSP points (IEC 60870-5-104) is shown below.
PATH: SETTINGS PRODUCT SETUP
BINARY INPUT / MSP
POINTS
Up to 256 binary input points can be configured for the DNP or IEC 60870-5-104 protocols. The points are configured by
assigning an appropriate FlexLogic™ operand. Refer to the Introduction to FlexLogic™ section in this chapter for the full
range of assignable operands.
The menu for the analog input points (DNP) or MME points (IEC 60870-5-104) is shown below.
