1 GENERAL
GENERAL
This document specifies a subset of the DNP3-1999 serial communications protocol used to transfer data
between a master computer station and the Series PM172 Powermeters.The document provides all necessary
information for developing third-party communications software capable of communicating with the PM172.
Additional information concerning communications operation, configuration of communications parameters, and
communications connections is found in the Series PM172 Installation and Operation Manual.
IMPORTANT
1. The voltage parameters throughout the protocol can represent line-to-neutral or line-to-line voltages
depending on the wiring mode selected in the instrument. When the 4LN3, 3LN3 or 3BLN3 wiring mode is
selected, the voltages will be line-to-neutral; for any other wiring mode, they will be line-to-line voltages. In
4LN3, 4LL3, 3LN3, 3LL3, 3BLN3 and 3BLL3 wiring modes, harmonic voltages will represent line-to-neutral
voltages. In a 3-wire direct connection, harmonic voltages will represent line-to-neutral voltages as they
appear on the instrument's input transformers. In a 3-wire open delta connection, harmonic voltages will
comprise L12 and L23 line-to-line voltages.
2. In 3-wire connection schemes, the unbalanced current and phase readings for power factor, active power,
and reactive power will be zero, because they have no meaning. Only the total three-phase power values can
be used.
3. Most of the instrument’s advanced features are configured using multiple setup parameters that can be
accessed in contiguous registers. When writing the setup registers, it is recommended to write all the
registers at once using a single request, or to clear (zero) the setup before writing into separate registers.
Each written value is checked for compatibility with the other setup parameters, and if the new value does not
conform to them, the request will be rejected.

2 DNP PROTOCOL
DNP PROTOCOL
Introduction
DNP3-2000 (Distributed Network Protocol) is an open standard designed by Harris Control Division. DNP defines
a command-response method of communicating digital information between a master and slave device. Detailed
information regarding DNP3-2000is available in the “Basic 4 Document Set” which can be obtained from the DNP
User Group. This document describes a LEVEL 2 DNP3-2000 communication protocol implemented between a
master station and a slave PM172 instrument.
PM172 Deviation from Standard
The PM172 does not support unsolicited requests or hardware collision avoidance.
The data link layer differs from the Basic 4 specifications because of the master-slave relationship between
devices. When the Powermeter receives a request, no further requests can be sent until after the Powermeter
makes the appropriate response.
DNP Implementation
Overview
The PM172, like most devices, retrieves regular analog and binary data from the instrument by executing directed
(non-broadcast) Read requests.
Binary-Output-Status objects and Analog-Output-Status objects are sent with flags that always indicate ONLINE.
A Binary-Output-Status object that indicates the current state of a control digital point (relay) uses remote forced
data as well as local forced data bits. The value of a state bit indicates the current state of the digital output point.
The PM172 executes the parameter clear function and demands resets using the Direct-Operate (or SBO/Operate
or Direct-Operate-No-Acknowledge) command to specified points of the Control-Relay-Output-Block object.
Issuing the Direct-Operate (or SBO/Operate or Direct-Operate-No-Acknowledge) command to appropriative points
of the Analog-Output-Block object can change the setup parameters. The DNP functions Write, Cold-Restart and
Delay Measurement are also supported by the PM172. Refer to Appendix A for specific requests and responses.
Appendix B contains the standard DNP Device Profile Document.
The Powermeter attempts to respond with the same object variation and qualifier as those in the request.
Exceptions to this rule include changing variation 0 to a specific variation and changing qualifier code 6 to 1.
If the Powermeter receives an invalid request, it sets the internal indication to the error code. The following
internal indication bits are supported:
Octet
Position
Bit
Position
Description
0 0 Set when a request received with a broadcast destination address. Cleared after next
response.
0 7 Device restart - set when the instrument powers up or after executing Cold Restart, cleared
by writing zero to object 80.
0 4 Time-synchronization required from the master. Cleared when master sets the time.
0 5 Set when the instrument is in the Local state(is being programmed via the front panel).
Cleared when the instrument is in the Remote state.
1 5 Set when the current configuration in the instrument is corrupted. May also be set as a result
of the legal changes in the setup configuration whenever another setup is affected by the
changes made. Cleared when either setup is reloaded.
Class 0 Response
The PM172 DNP implementation supports a wide variety of messages. The most common method to extract DNP
static object information is to issue a Read Class-0 request.
There is an option for assigning objects to be polled via Class 0 requests. When this option is used, the Class 0
response includes all static object points specified by the Class 0 Point Assignment Setup Registers (see Table 3-

6
30). By default, the following points are specified by the Class 0 Point Assignment setup: 32 first Analog Input
points from Table 3-1, 3 Analog Output first 3 points from Table 3-2, 2 Binary Input points represented Status
Inputs and 2 Binary Input points represented Relay Status (see Table 3-13).
Object Point Mapping and Event Objects
The PM172 has a special mapping mechanism allowing you to map either static object point onto predefined point
range. A total of 32 points are available for mapping. DNP static objects can be accessed directly by using the
dedicated object point number. DNP event objects can be generated and accessed only through a mapping
mechanism.
You can map any of the 32 mapping points to either Analog Input, Binary Input or Binary Counter object point. By
default those are factory mapped to the first 32 points of the Analog Input object: 32 points from the Basic Data
Registers (see Table 3-1). To re-map these, you must define the required number of points for each allowable
DNP object in the DNP Options Setup (see Table 3-8), and then configure each point individually to be polled as
an event source, via the DNP Event Setpoints Setup (see Table 3-9). For any mapped static object point, you can
enable a corresponding event object point. Note that any changes made to the DNP Options Setup cause a reset
of the DNP Event Options Setup points to their defaults.
All event options are disabled by default. Since a mapped static point is configured to create DNP Event objects,
events are generated for this point as its value or state changes. Two different scan time rates are used for polling
events:
- 200 ms for Binary Counter and Analog Input points;
- 50 ms for Binary Input points.
The memory consumption for keeping events depends on the event objects variation (DNP object size). The
maximum buffer size (MBS) per DNP Event Object/ Event Class is 256 byte. The maximum number of events that
the instrument can hold can be calculated as follows:
Maximum Events Number = MBS / (DNP Event Object Size + 1)
For example, the instrument can hold up to 21 measures of the 32-bit Analog Change Event With Time Object:
(256 / 12) or up to 32 measures of the 8-bit Binary Change Event With Time Object: (256 / 8).
To suppress mapping, explicitly set all registers that specify the number of the Analog Input, Binary Input and/or
Binary Counter objects to 0. In this case PM172 supports Static Operation Polling only.
DNP Address
The instrument on a DNP link must have a unique address. The PM172 allows one of 256 addresses to be
selected. The selectable addresses have a range of 0-255. DNP uses the address 65535 for broadcast function.
Note that a broadcast request never generates a DNP response.
Transaction Timing
To allow the master to switch the communication link, the Powermeter minimum response time must be at least
3.5 character time (depending on the baud rate) and at least 5 ms. Table 2-1 shows the actual response time
measured at 9600 bps.
Table 2-1 Response Time
No. of Parameters Typical response time, ms Maximum response time, ms
1 10 12
5 15 16
10 21 22
43 (Object 30:3) 45 62
Note that Direct-Operate (or SBO/Operate or Direct-Operate-No-Acknowledge) requests for reset/clear registers
and setpoint changing are immediately confirmed.
Scaling 16-bit Analog Inputs
With the Analog-Input objects, any of variations 1 through 4 can be used. Variations specified in the tables in
Section 3 show those that should be used to read a full-range value without a possible over-range error when no
scaling is used to accommodate the value to the requested object size.
When over-range occurs, a positive value is reported as 32767 and a negative value as -32768, with the over-
range bit being set to 1 in the flag octet if a variation 2 is requested. To avoid over-range errors when a variation 2
or 4 is required, a liner scaling may be used (see Section 3, DNP Options Setup) to scale 32-bit analog readings
to 16-bit Analog Input objects. By default, scaling is disabled.

7
When scaling is enabled, either analog input requested with variation 2 or 4 will be scaled to the range of -32768
to 32767 for bi-directional parameters (such as power and power factor), and to the range of 0 to 32767 for single-
ended positive parameters (voltage, current, frequency, etc.). To get a true reading, the reverse conversion should
be done using the following formula:
Y = ((X – DNP_LO) ×(HI - LO)) /(DNP_HI – DNP_LO) + LO
where:
Y - the true reading in engineering units
X - the raw input data in the range of DNP_LO – DNP_HI
LO, HI - the data low and high scales in engineering units (specified for each Analog-Input point, Section 4)
DNP_LO - DNP low conversion scale: DNP_LO = -32768 for a point with a negative LO scale, DNP_LO = 0 for
a point with a zero or positive LO scale
DNP_HI - DNP high conversion scale: DNP_HI = 32767
EXAMPLE
Suppose you have read a value of 201 for point 3 that reports a current reading (see Table 3-1). If your instrument
has CT primary current 5000 A, then the current high scale is HI = 2.0×5000 = 10000, and the current reading in
engineering units will be as follows:
(201 - 0) ×(10000 - 0)/(32767 - 0) + 0 = 61.34A
Scaling 16-bit Binary Counters
Binary counters are stored in the device in 32-bit integer format. Using 16-bit Binary Counter objects can cause
over-range errors if the counter value exceeds 32767. Scaling binary counters (see DNP Options setup in Section
3.9) allows changing a binary counter unit from 1 to 1000 in powers of 10 to accommodate a 32-bit counter value
to 16-bit object format. If the scaling unit is greater than 1, the counter value is reported being divided by the
scaling unit. To get the actual value, multiply the counter reading by the selected scaling unit.

1The parameter limits are as follows:
Imax (200% over-range) = 2 ×CT primary current [A]
Direct wiring (PT Ratio = 1):
Vmax (690 V input option) = 828.0 V
Vmax (120 V input option) = 144.0 V
Pmax = (Imax ×Vmax ×3) [kW x 0.001] if wiring mode is 4LN3, 3LN3 or 3BLN3
Pmax = (Imax ×Vmax ×2) [kW x 0.001] if wiring mode is 4LL3, 3OP2, 3DIR2, 3OP3, 3LL3 or 3BLL3
Wiring via PTs (PT Ratio > 1):
Vmax (690 V input option) = 144 ×PT Ratio [V]
Vmax (120 V input option) = 144 ×PT Ratio [V]
Pmax = (Imax ×Vmax ×3)/1000 [MW x 0.001] if wiring mode is 4LN3. 3LN3 or 3BLN3
Pmax = (Imax ×Vmax ×2)/1000 [MW x 0.001] if wiring mode is 4LL3, 3OP2, 3DIR2, 3OP3, 3LL3 or 3BLL3
2When using direct wiring (PT Ratio = 1), voltages are transmitted in 0.1 V units, currents in 0.01 A units, and powers in
0.001 kW/kvar/kVA units. For wiring via PT (PT Ratio > 1), voltages are transmitted in 1V units, currents in 0.01 A units,
and powers in 1 kW/kvar/kVA units.
3To get block interval demand readings, set the number of demand periods equal to 1 (see Table 3-4).
4When the 4LN3 or 3LN3 wiring mode is selected, the voltages will be line-to-neutral; for any other wiring mode, they will be
line-to-line voltages.
5Variations specified in the table show those that should be used to read a full-range value without a possible over-range
error when no scaling is used to accommodate the value to the requested object size (see Section 3, Scaling Analog Input
Objects).

2Available with F/W version 4.88.8 or later.
The Analog Input object variation sets the default variation for the Analog Input objects, which will be used if no
specific variation is requested by a master station with the qualifier code 06 (variation 0). By default, it is set to the
16-bit Analog Input object without flag (object 30, variation 4).
The Analog Input Scaling is used to control the scaling of the 16-bit analog input points. By default, the scaling is
ON. Choosing 32-bit objects (object 30, variations 1, 3) for analog input points disables this setting.
The meter supports up to 32 Analog Input, Binary Input and Binary Counter points that can generate events. By
default, 32 Analog Input points 0 through 31 are configured for generating events. To re-map the current setting,
write desired values into Analog Output points 45-47.
The Select Before Operate command causes the PM172 to start a timer. The Operate command must be sent
before the timeout defined by the Select/Operate Timeout expires.
The meter requests time synchs when the time specified by the Time Synch Period parameter has elapsed. The
bit 4 of the first octet in the internal indication word will be set. The master synchronizes the time by writing the
Time and Date object to the meter.

2The source of the DNP events recorded to the device Event log is identified as the general Setpoint #17.
Either an operating threshold, or deadband should be specified to generate events for numeric (AI and BC)
objects, using one of the three allowable relations:
1. Delta – a new event is generated when the absolute value of the difference between the last reported value of
the point and its current value exceeds the specified deadband value.
2. More than (Over) - a new event is generated when the point value rises over the specified threshold, and then
when the point value returns below the threshold taking into consideration a predefined hysteresis.
3. Less than (Under) - a new event is generated when the point value drops below the specified threshold, and
then when the point value returns above the threshold taking into consideration a predefined hysteresis.
A hysteresis for the point return threshold is 0.05 Hz for frequency and 2% of the operating threshold for all other
points.
The scan time for binary input change events is 50 ms with a timestamp precision at +/-10 ms. The scan time for
analog input and binary counter change events is 200 ms.
Freeze Requests on Binary Counter Objects
Acceptable object variation and qualifier combinations included in the device response are specified in Table 3-7.
The Immediate Freeze, Immediate Freeze-No Acknowledgement, Freeze and Clear, Freeze and Clear-No
Acknowledgement DNP commands can be applied to all Binary Counters objects supported by the PM172. These
registers are used to access the Frozen Binary Counters.

Warning
Any attempt to issue a freeze and clear (or freeze and clear - No acknowledgement) to object 20
variation 0 using function code 0x09 (or 0x10) and the data qualifier 0x06 causes all counters
specified in this manual to be reset to zero.
Resetting Energy, Demands, Counters and Min/Max log
The energy value can be reset to zero by issuing the Direct-Operate (or SBO/Operate or Direct-Operate-No-
Acknowledge) command using the Control-Relay-Output-Block object to point 0. The request must use the
operation Pulse-On. Issuing the same parameters and Direct-Operate (or SBO/Operate or Direct-Operate-No-
Acknowledge) command to points 1-3 can reset the maximum demands.

BI indicates Single-Bit Binary-Input points (Read).
Alarm Status Registers
These registers are used to retrieve the status alarm parameters from the instrument.
NOTE
The PM172 provides the self-check alarm register.
The self-check alarm points indicate possible problems with the instrument hardware or setup configuration. The
hardware problems are indicated by the appropriate points, which are set whenever the instrument fails self-test
diagnostics, or in the event of loss of power. The dedicated binary point indicates the setup configuration
problems, which is set when either configuration register is corrupted. In this event, the instrument will use the
default configuration. The configuration corrupt bit may also be set as a result of the legal changes in the setup
configuration since the instrument might implicitly change or clear other setups if they are affected by the changes
made.
Issuing the Direct-Operate (or SBO/Operate or Direct-Operate-No-Acknowledge) command using the Control-
Relay-Output-Block object (with the code operation Latch-Off) to points from range 64 to 75 can reset hardware
fault points. The configuration corrupt status point is also reset automatically when you change setup either via the
front panel or through communications.
