Technical reference

This section describes the IEC 61850 data modeling. This section also contains

attributes and a list of status codes.

Document conventions1.4.

The following conventions are used for the presentation of material:

•

The words in names of screen elements (for example, the title in the title bar of a

window, the label for a field of a dialog box) are initially capitalized.

•

Capital letters are used for the name of a keyboard key if it is labeled on the keyboard.

For example, press the ENTER key.

•

Lowercase letters are used for the name of a keyboard key that is not labeled on the

keyboard. For example, the space bar, comma key, and so on.

•

Press CTRL+C indicates that you must hold down the CTRL key while pressing

the C key (to copy a selected object in this case).

•

Press ESC E C indicates that you press and release each key in sequence (to copy

a selected object in this case).

•

The names of push and toggle buttons are boldfaced. For example, click OK.

•

The names of menus and menu items are boldfaced. For example, the File menu.

•

The following convention is used for menu operations: MenuName > Menu-

Item > CascadedMenuItem. For example: select File > New > Type.

•

The Start menu name always refers to the Start menu on the Windows taskbar.

•

System prompts/messages and user responses/input are shown in the Courier font.

For example, if you enter a value out of range, the following message is displayed:

Entered value is not valid. The value must be 0 to 30.

Introduction2.

Product overview2.1.

The DNP OPC Server provides methods for OPC clients to exchange data with devices

communicating via the DNP protocol.

DNP 3.0 OPC Server features2.2.

The Distribute Networks Protocol (DNP) 3.0 is a standards-based communication protocol

designed for electric utility, water, oil & gas and security systems. DNP is hardware-

independent and works with a variety of networks enabling communication between

substation computers, Remote Terminal Units (RTUs), Intelligent Electronic Devices

(IEDs) and master stations over serial or LAN-based systems.

The physical layer can be any bit-serial physical layer such as RS-232 C, RS-485 or

ethernet.

Configuration3.

About this section3.1.

This section guides you in the configuration tasks required before you can start using

the DNP OPC Server. For information on the IEC 61850 data modeling, refer to the

COM600 User's Guide.

Start Communication Engineering Tool (CET) and either open a project where at least

one DNP OPC server is present, or where a new DNP OPC server is to be added. You

can also open and name a new project to include one or more DNP OPS servers.

1. Select File > Open/Manage Project....

2. In the Open/Manage Project dialog, select the required location for the project:

•

Projects on my computer.

•

Projects on network.

3. Select New Project on the left.

•

Enter a Project Name. The Description is optional.

4. Click Create.

5. Click Open Project.

Overview of configuration3.2.

Before you can start using the DNP OPC Server, you need to build and configure an

object tree in Communication Engineering Tool (CET) to define the Communication

structure within the Gateway object. An object tree contains the following branches:

•

Gateway

•

DNP LAN OPC Server

•

DNP LAN Channel

•

Logical Device objects

•

Logical Node objects

•

Data objects

After you have added the necessary objects to the object tree in the communication

structure, you need to configure them.

The configuration work can basically be divided into two separate tasks:

1. building the object tree, and

2. configuring object properties.

First, you need to build an object tree. This is done by adding objects to the object tree,

see 3.3.1, General about building object tree.

In the object tree communication view, you can see the DNP OPC Server object and its

child objects such as channels, devices, and data objects. After you have added the

18

1MRS756566

COM600 Station Automation Series

DNP 3.0

LAN/WAN Master

(OPC) 3.2

User's Guide

necessary objects to the object tree in the communication structure, you need to configure

them, see 3.4.1, General about configuring objects.

When configuring OPC servers the following characters cannot

be used in object names: \ ` ' ' #

Building object tree3.3.

General about building object tree3.3.1.

The object tree is built in the Communication structure of Communication Engineering

Tool (CET). It is built by adding objects in a logical order starting from the Gateway.

You have several possible ways to add objects to the object tree in the Communication

structure:

•

You can right-click the object to which you want to add a child object. Then select

New > Object type group > Object name, for example

•

You can right-click the object type and select New > New. A New Object window

appears. Select the object type you want to add and click OK or double-click it.

•

You can copy the object.

Add the objects in the following order:

1. Gateway

2. DNP LAN OPC Server

3. DNP LAN Channel

4. Logical Device objects

5. Logical Node objects

6. Data objects

For information on building a substation structure, refer to COM605, COM615 HMI

Configuration Manual.

Adding Gateway object3.3.2.

To start building the object tree, add a Gateway object in the Communication structure

by selecting the project name, right-click it and select New > Communication > Gate-

way.

Adding DNP OPC Server object3.3.3.

After the Gateway object has successfully been added, you can continue building the

object tree by adding DNP OPC Server object.

19

DNP 3.0

LAN/WAN Master

(OPC) 3.2

COM600 Station Automation Series

1MRS756566

User's Guide

To add DNP OPC Server object:

1. Select the Gateway object in the communication structure and right-click it.

2. Add DNP OPC Server object.

By using the SCL Import function, it is possible to import an entire server’s or individual

devices’ configurations without having to insert them manually. To open the SCL Import

function, right-click the desired object, and select SCL Import.

Connectivity Packages for certain protection and control devices may also support other

ways to build this structure, depending on the configuration of an individual device, for

example device-related object types and wizards. Typically, Connectivity Packages

include SCL description files which need to be installed. For further information on these

Connectivity Packages, see the Connectivity Package of a certain device in the product

documentation.

Adding DNP Channel objects3.3.4.

After the server object has been successfully added, you can continue building the object

tree by adding DNP Channel objects.

To add DNP Channel object:

1. Select DNP OPC Server object.

2. Right-click the DNP OPC Server object.

3. Add DNP Channel object.

4. Rename the new object. Note that the names of the DNP Channel objects have to

be unique.

Adding DNP IED objects3.3.5.

After adding a subnetwork you can add device objects.

To add a Device object:

1. Select a Subnetwork object.

2. Add DNP IED object.

3. Rename the new object. Note that the names of the devices within DNP channel

have to be unique.

You should not have more than 30 devices per each channel.
