1.0 DNP INTERFACE
1.1 Description
The DNP network is a "MASTER" to "SLAVE" network; that is to say, one node asks a question and a
second node answers. A NODE is a DNP device (RTU, Computer, M65x, M66x, etc.) that is connected to
the network. Each DNP NODE has an ADDRESS in the range of 0 to 65519, and it is this address that
allows a MASTER to selectively request data from any other device. DNP uses the address range 65533-
65536 for broadcast functions. Broadcast requests never generate DNP responses.
The DNP implementation in the M6xx conforms to DNP3 specifications as defined by DNP.org (derived
from the Harris IED (Intelligent Electronics Devices) implementation guidelines). Data obtained by the
DNP READ CLASS 0 command is configurable. Individual items can also be read using READ BINARY
OUTPUT STATUS or READ ANALOGUE INPUT or READ COUNTER or READ ANALOGUE OUTPUT
STATUS or READ BINARY INPUT or READ FROZEN COUNTER commands.
The Energy values can be reset to zero by issuing the DIRECT OPERATE, DIRECT OPERATE NO
ACKNOWLEDGE, or SELECT BEFORE OPERATE by using the CONTROL RELAY OUTPUT BLOCK
object.
The Demand values can be reset by issuing the same DIRECT OPERATE, DIRECT OPERATE NO
ACKNOWLEDGE, or SELECT BEFORE OPERATE command to the other points of this object.
M6xx ANALOGUE OUTPUTS have two read/write values: Tag and Tag1. They can be changed by
issuing DIRECT OPERATE, DIRECT OPERATE NO ACKNOWLEDGE, or SELECT BEFORE
OPERATE by using the ANALOGUE OUTPUT BLOCK object. Due to the limited number of FLASH write
cycles, they SHOULD NOT be written continuously.
Four legacy values are also presented. They are CT Scale Factor Normalized Ratio and Divisor, and VT
Scale Factor Normalized Ratio and Divisor. They are derived from the PT scale and CT scale configured
through the browser interface.
The SELECT BEFORE OPERATE arm timeout value is configurable from zero to 64 seconds.
1.2 DNP Address
The serial port in the M65x can be set up to be RS-232 or RS-485, and support baud rates from 9600 to
115200. Configuring the Serial Ports can be accomplished by using the display buttons or via a standard
web browser while setting the address is done via a web browser only.
Each DNP instrument responds to a single destination address in the range 0-65519. Each instrument on
a DNP link must have a unique address. M6xx meters will allow any of the 65520 addresses to be
selected. DNP instruments also use a BROADCAST address range of 65533-65535. Requests sent to a
BROADCAST address cause the instrument to execute the function but not generate a response.
1.3 Transaction Timing
M6xx meters complete a set of calculations approximately every 100ms. Incoming messages are parsed
every 50ms.
1.4 Object Format
M6xx meters report all static measurements via the use of three static objects. These objects include
COUNTER (object 20, variations 1, 2, 5 and 6), ANALOGUE INPUT (object 30, variations 1, 2, 3 and 4)
and BINARY INPUT (object 2, variations 1 and 2). These objects are read only and cannot be modified
by DNP MASTER devices.
ANALOGUE OUTPUT STATUS (object 40, variation 2) can read CT and VT configuration information and
two tag registers. ANALOGUE OUTPUT BLOCK (object 41, variation 2) can be used to write the
Tag/Tag1 register through DNP. Due to the limited number of FLASH write cycles, Tag/Tag1 SHOULD

DNP3 Manual M6xxD/EN M/B
M6xx Page 6
NOT be written continuously. Pseudo output points (such as demand and energy resets) are reported
using the BINARY OUTPUT STATUS (object 10, variation 2).
M6xx meters are capable of reporting ANALOGUE CHANGE EVENTS (object 32, variations 1 through 4).
Any ANALOGUE INPUT can be configured to report as a CLASS-1, CLASS-2, or CLASS-3 ANALOGUE
CHANGE EVENT. Point, Class, Analogue Deadband Values and Object Variation are all selectable by
use of the Ethernet service port and web browser. The default Object Variations are selectable by Object
(not by point). All ANALOGUE CHANGE EVENTS can be configured to report with or without time.
M6xx meters support frozen counter events (object 21, variations 1, 2, 5 and 6 which are 16 or 32-bit with
or without time).
M6xx meters support one BINARY INPUT (object 1, variations 1 and 2) and one BINARY INPUT
CHANGE event (object 2, variations 1, 2, and 3). The single binary input is derived from the OR of the
bits from the Health status word.
The DNP protocol allows each device to determine the best method of data transfer. The M6xx meters
support this by selecting the most appropriate response variation when either the requested variation is 0
or a CLASS-0 read is requested. Both COUNTER and ANALOGUE INPUT objects allow optional flags to
be used. If a value is requested as variation 0, the M6xx meter responds as selected with the default
variation selected through the browser.
When reading objects, the Health Check point (object 30, point 0) should always be read and checked
before interpreting data, since some failure modes will cause erroneous data to be presented (See
Section 1.8). The majority of the points are represented in Normalized 2's complement format. For
conversion of the point data into engineering units, please refer to Section 1.6. Appendix A provides the
Legacy or Bitronics Legacy Fixed (BiLF) point set used in the M6xx.
NOTE: Unless otherwise specified, all points are READ ONLY.
1.4.1 DNP3 Calculation-Type Codes
The DNP3 Type codes for Optimal Resolution that are applicable to the point assignments in the
appendix tables are highlighted within the following Calculation Type table:
