1 General
This document specifies a subset of the DNP3 communications protocol used to transfer data
between a master computer station and the PM174. The document provides the complete
information necessary to develop third-party communications software capable of
communication with the Series PM174 instruments.
For additional information concerning communications operation, configuring the
communications parameters, and communications connections see the PM174 Installation and
Operation Manual.

6
2 DNP 3.0 Protocol Implementation
DNP3 (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 is available in the
“Basic 4 Document Set” which can be obtained from the DNP User Group.
2.1 Deviations from Standard
The PM174 implements Level 2 of the DNP3 communication protocol. The device 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 device receives a request, no further requests can
be sent until after the device makes the appropriate response.
2.2 DNP Implementation
The PM174, like most devices, allows retrieving regular analog and binary data from the
device 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 PM174 executes the parameter clear function and demands resets using the Direct-
Operate, SBO/Operate or Direct-Operate-No-Acknowledge command to specified points of
the Control-Relay-Output-Block object.
Issuing the Direct-Operate, SBO/Operate or Direct-Operate-No-Acknowledge command to
appropriative points of the Analog-Output-Block object can change the setup parameters.
The device also supports the DNP functions Write, Cold-Restart and Delay Measurement.
Refer to Appendix A for specific requests and responses. Appendix B contains the standard
DNP Device Profile Document.
The device 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 device 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 device 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 device is in the Local state. Cleared when the device in the Remote state.
1 5 Set when the current configuration in the device 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 by writing zero to points 64-75 using object 12.
2.2.1 Class 0 Response
The PM174 DNP implementation supports a wide variety of messages. The most common
method of getting static object information from the meter via DNP is to issue a read Class
0 request.
The PM174 allows you to configure the Class 0 response by assigning ranges of points to be
polled via Class 0 requests (see Section 3.9, DNP Protocol setup).

7
2.2.2 Event Objects
The PM174 allows you to assign any static object point to a predefined object change event
point for Class 1, Class 2 or Class 3 event polling. A total of 64 change event points are
available. You can assign any of the Analog Input, Binary Input or Binary Counter static
points to the corresponding change event point through the DNP Event setup (see Section
3.9). You can also link any point to Class 1, Class 2 or Class 3 object polling.
By default, a change event point index is the same as for the corresponding static object
point. The PM174 gives you an option to re-map a static point index for the corresponding
event point starting with index 0, separately for each object type - Analog Input, Binary
Input or Binary Counter change events. For example, if the re-mapping option is active and
you first assign static point AI:23 (1-sec frequency) to an event Class 1 point, the
corresponding Analog Input change event point will be identified as point 0 in the Class 1
poll response.
Each point assigned to an event class can be separately enabled or disabled for scanning.
Each point can also be linked to the common device Event log so that each change would be
recorded to the Event log under common Setpoint #17.
The conditions for Analog Input change events can be specified by either an operating
threshold, or a deadband, using one of the following three relations:
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;
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;
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.
For Binary Counter and Binary Input change events, a Delta relation is only applicable.
The number of event points for each object type (Analog Input, Binary Input or Binary
Counter) is limited through the DNP Options setup (see Section 3.9). Every time you
change the number of points for any of the objects, the device clears all event buffers and
links the default set of static points to each event object type.
The scan time rates for polling events of different types are as follows:
- 1 cycle for Binary Input points
- 200 ms for Binary Counter and Analog Input points
The memory consumption for keeping events depends on the event objects variation, or
DNP object size. For each event object type and event class, the device uses a separate
buffer. The maximum buffer size per DNP event object/event class is 512 bytes. The
maximum number of events per class that the device can hold can be calculated as follows:
Maximum number of events = 512/(DNP Event Object Size + 1)
For example, the device can hold up to 512/12=40 measures of the 32-bit Analog change
event with Time objects, or up to 512/8=64 measures of the 8-bit Binary change event with
Time objects.
To disable change event objects, set to 0 all registers that define the number of the Analog
Input, Binary Input and Binary Counter objects to generate events. In this case, the device
will support only static objects.
2.2.3 Device Address
Each device on a DNP link must have a unique address. The PM174 allows a device address
in the range of 0 to 65532 to be selected. The DNP master can use addresses 65533 to
65535 for broadcast requests. A broadcast request never generates a DNP response.

8
2.2.4 Transaction Timing
The PM174 response time to master requests is indicated in Table 2-1.
Table 2-1 Response Time
Response Time, msBaud Rate, bps Min Max Typical
9600 13 15 13
19200 11 12 11
57600 9 10 9
115200 9 10 9
The Direct-Operate, SBO/Operate or Direct-Operate-No-Acknowledge requests for
reset/clear registers and setpoint changing are immediately confirmed.
2.2.5 Scaling 16-bit Analog Inputs
Any of the variations 1 through 4 can be used with the Analog Input objects. Variations
specified in Sections 3.1 and 3.5 show those that can 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 in the flag octet being set to 1 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
to scale 32-bit analog readings to 16-bit Analog Input objects (see Section 3.9, DNP Options
setup). Scaling is enabled in the device by default.
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- True reading in engineering units
X- Raw input data in the range of DNP_LO – DNP_HI
LO, HI - Data low and high scales in engineering units (for device data scales, see
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
If you have read a value of 201 for point AI:3 that shows the I1 current (see Section 3.1)
and the CT primary current is 200A (the high current scale is 2×200 = 400A), then the
current reading in engineering units is as follows:
(201 - 0) ×(400 - 0)/(32767 - 0) + 0 = 2.45A
2.2.6 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.

9
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.
2.3 Password Protection
The PM174 has a password protection option allowing you to protect your setups,
cumulative registers and logs from being changed or cleared through communications. You
can disable or enable password protection through communications or via the front display.
For details, refer to your instrument Installation and Operation Manual.
When password protection is enabled, the user password you set in your instrument should
be written into the device authorization register (point AO:192) before another write
request is issued. If the correct password is not supplied while password protection is
enabled, the instrument will respond to all write requests with the exception response
“Control operation not supported for this point”. It is recommended to clear the password
register after you have completed your changes in order to activate password protection.
