per function. The manual can be used to find out when and for what purpose a typical

protection function can be used. The manual can also provide assistance for calculating

settings.

The technical manual contains operation principle descriptions, and lists function

blocks, logic diagrams, input and output signals, setting parameters and technical data,

sorted per function. The manual can be used as a technical reference during the

engineering phase, installation and commissioning phase, and during normal service.

The electrical warning icon indicates the presence of a hazard which

could result in electrical shock.

The warning icon indicates the presence of a hazard which could result

in personal injury

.

The caution hot surface icon indicates important information or

warning about the temperature of product surfaces.

The caution icon indicates important information or warning related to

the concept discussed in the text. It might indicate the presence of a

hazard which could result in corruption of software or damage to

equipment or property.

The information icon alerts the reader of important facts and

conditions.

The tip icon indicates advice on, for example, how to design your

project or how to use a certain function.

Although warning hazards are related to personal injury, it is necessary to understand

that under certain operational conditions, operation of damaged equipment may result

in degraded process performance leading to personal injury or death. It is important

that the user fully complies with all warning and cautionary notices.

Section 2 DNP3 overview

GUID-9CDAE3C1-07F5-493F-A1F1-196C2F48DB16 v1

DNP3

is a communication protocol used between components in process automation

systems. Its main use is in utilities such as electric and water companies. Usage in

other industries is not common, although technically possible. Specifically, it was

developed to facilitate communications between various types of data acquisition and

control equipment. It plays a crucial role in

SCADA systems, where it is used by

SCADA master stations (aka Control Centers), RTUs, and IEDs.

2.1 DNP3 standard

AMU0600507 v14

The DNP3 protocol was developed by Westronic based on the early versions of the

IEC 60870-5 standard telecontrol protocol specifications. DNP is now governed by

IEEE Std 1815-2012 IEEE Standard for Electric Power Systems Communications -

Distributed Network Protocol (DNP3)

www.dnp.org.

The protocol is based on the EP

A, a simplified model of the ISO/OSI model. It

specifies the data link layer, the application layer and a transport pseudo-layer. To

1MRK 511 391-UUS A Section 2

DNP3 overview

670 series 2.2 ANSI 11

Communication protocol manual

support advanced RTU functions and messages larger than the maximum frame length

as defined by the IEC document 60870-5-1, the DNP3 data link is intended to be used

with the mentioned transport pseudo-layer

. As a minimum, this transport layer

implements message assembly and disassembly services.

Physical layer

Even though the standard does not specify the physical layer, it does however specify

how to operate in a networked environment and also suggests how to avoid collisions

between simultaneously sending devices.

Many implementations use serial communication based on RS-232, RS-485 or even

fibre optics.

DNP3 can also be used over packet-oriented networks such as TCP/IP and UDP in

which, for example, Ethernet may be used. In this case DNP3 can be said to be

tunneled over TCP/IP or UDP.

Additional information on the DNP3 physical layer is available at the

DNP Users Group at www.dnp.org.

Data link layer

The DNP3 data link layer is designed to operate with asynchronous or synchronous bit

serial physical layers. Fully balanced transmission procedures were adopted to support

spontaneous transmissions from remotes.

Data link functions include:

• Performing message data link retransmissions.

•

Packing user data into the defined frame format includes CRC and transmitting the

data to the physical layer.

• Unpacking the data link frame received from the physical layer into user data,

checking and removing CRC.

• Controlling the physical layer.

• In unsolicited reporting mode, performing collision avoidance/detection

procedures to ensure reliable transfer of data across the physical link.

• Responding to all valid frames received from the physical layer.

Data link responsibilities:

• Exchange of Service data units (SDUs) between peer DNP3 data links

• Error notification to data link user

• Sequencing of SDUs

• SDU delivery quality.

Section 2 1MRK 511 391-UUS A

DNP3 overview

12 670 series 2.2 ANSI

Communication protocol manual

Link-layer confirm usage is not recommended and the implementation is optional. The

IED does not request data-link layer confirmations for TCP/IP communication.

See the DNP technical bulletin TB1998-0402, section 3 for details at

www.dnp.org.

Transport pseudo-layer

To support advanced R

TU functions and messages exceeding the maximum data link

frame length, a transport pseudo-layer which implements message assembly and

disassembly services was adopted.

Transport functions:

• Fragmenting user data into one or more data link frames and transmitting the data

to the data link layer

• Assembling the data link frames received from the data link layer into user data

• Controlling all aspects of the data link excluding data link configuration

Transport responsibilities:

• Exchange of SDUs between peer DNP3 transport pseudo layers

• Error notification to transport users

• Sequencing of SDUs

Application layer

The application layer is responsible for performing operations on data objects defined

by the device or on the device itself. These operations include returning actual values

(read function), assigning new values (write function) if the object represents control

points, arming and energizing the output point (select, operate or direct operate

functions) and if counters are used, reading actual values and clearing the counters.

DNP3 uses the term point to identify an entity, and these entities can be categorized

into point-types, such as analogs or binaries. Points are addressed by giving them an

index number and an object is a formatted representation of data from a point. These

objects can be assigned to classes in order to organize events and current values into

categories. The DNP3 protocol defines four data classes to organize data reporting.

Communication modes

The IED supports four DNP3 communication modes.
