Introduction
1.1 Introduction
ICN OPC Server is an Industrial IT enabled software product. It is an OPC Foundation
compliant server application (serial communications device interface) that allows
hardware devices to communicate with OPC Clients such as ABB Operate IT Products
and other software manufacturer's HSI packages like ICONICS’ Genesis32, Intellution's
FIX Dynamics and similar packages from Wonderware, CI Technologies and others. For
client software packages that are not OPC compliant, the server also supports dynamic
data entry (DDE) type links. ViZapp, Visual Application Designer, is also an OPC Client
that can use this OPC server to communicate with the devices it configures. The OPC
server handles the reading and writing of the device data. See Overview of OPC based
configuration for steps involved in configuring the client and server.
This OPC server supports MODCELL and MOD 30ML Controllers and MOD30
Instruments such as Controller, Recorder, Math Unit and Sequence and Logic Unit (SLU)
using the ICN (Instrument Communication Network) communication protocol.
The server is used to build the tag database that contains information about the tags such
as tag name, address, device (instrument) from which they are coming and communication
port settings. Any OPC Client application, such as OPC based HMI Software, can plug
and play with this and present the data to the user.
An OPC Client is included in the ABB ICN OPC Server. This monitor client is useful for
viewing live data and determining if configured tags are receiving correct data from the
hardware.
1.2 Definitions
1.2.1 ICN Protocol
ICN (Instrument Communication Network) is a master-less token passing protocol. It is
used for Peer-to-peer communication between the members on the ICN. It can also be
used for communication to host devices such as Computer and LCP (Local Control Panel).
The maximum number of devices on the ICN is 16. Each device should have a unique
address in the range of 0 – F Hex (0 – 15). Each device on the network is assured access to
the token every 250 ms. The device can receive or transmit messages or data when it has
the token.

ICN OPC Server Guide
Introduction
1.2.2 Mini-link and Mini-link External
Mini-link Internal (1731 and 1732N) or Mini-link External (1733N) is used for connecting
the ICN to a host computer. It is also considered to be a member on the ICN. The Minilink Internal is plugged into an ISA slot of the Personal Computer where as Mini-link
External is connected to a serial port of the Personal Computer. Boh types of Mini-links
can connect up to 2 ICNs. The Mini-link External has 2 serial ports (9 pin and 25 pin) for
connection to computers.
1.2.3 Built-in OPC Client
An OPC Client application is built-in with the ICN OPC Server for monitoring and
testing your Server’s configuration. It is this part of the OPC application that collects
data received by the OPC Server and presents to the user. The data presented by the
OPC Client is live.
OPC Client is useful for testing the communication between the devices and the OPC
Server. It can also be used for testing other 3rd party OPC applications connected to the
server.

Installation
2.1 Objectives
This chapter explains the installation procedure for the ICN OPC Server.
2.2 System requirements:
For running the ICN OPC Server, you need the following computer configuration and
software installed:
• Pentium 300 MHz or faster processor with 64 MB RAM.
• At least 100 MB of available hard disk space.
• CD ROM Drive (at least 4 speed, higher speed recommended)
• A SVGA monitor or better.
• Windows 2000 or Windows XP or Microsoft Windows NT 4.0. Service Release
4.0 or higher with Service Pack 5 or higher or Microsoft Windows 98 Second
Edition or Microsoft Windows 95 B Release with DCOM
• A mouse or other compatible pointing device.

ICN OPC Server Guide
Installation
2.3 Instructions:
The following procedure explains how to install ICN OPC Server on your computer. Start
your Microsoft Windows operating system.
Windows 95 needs DCOM (Distributed COM) for running the ICN OPC Server. The
ICN OPC Server setup will detect if DCOM was already installed on your computer. If
DCOM was not present, it will install it.
This is an issue with only Windows 95. If DCOM was already present in your Windows
95 system and is of a lower version, ICN OPC Server setup will update it.
Note also that DCOM is also installed as part of Internet Explorer 5.0 or higher and some
other programs.
ICN OPC Server also requires a software component called the OPC Data Access
Components.
The above programs are installed by ICN OPC Server in the background during the Setup
and do not require any user inputs.
Close all applications that are running in your computer currently before starting the
ICN OPC Server setup. If a previous installation of the software exists, you will be
prompted to choose an option from the list: Modify, Repair and Remove.
2.3.1 ICN OPC Server Setup
1. Insert the ICN OPC Server CD into the CD-ROM drive.
In most computers where auto run is enabled, the setup will start automatically as soon as
you put the ICN OPC Server CD in the drive and close the drive. If auto run is not enabled
in your computer you will need to run it manually.
To run the setup manually, select Run from the Start Menu of Windows. The Run dialog
box will appear as shown below:

3.1 Objectives
In this lab, we will configure an ICN OPC Server database and add a device to it. We will
use this database to download the PIDLAB Strategy from the previous lab to the MOD
30ML instrument.
We will also populate the OPC database with tags using the Modcell Interface File (.MIF)
created in the previous lab and monitor the data by reading them from the instrument
using the built-in OPC Client of the ICN OPC Server.
After completing this lab you should be able to:
• Configure a ICN OPC database
• Download the Instrument document (strategy)
• View the signals using the built-in OPC Client

bottom.
By doing this you can populate the OPC Server tag database with tags that will be
automatically created from the attributes defined in the MIF file (attributes added to
your Configured List blocks in the strategy). This will save a tremendous amount of
engineering time as you do not have to create each tag manually.
This will also create a list of Tags in the VizApp Configurator automatically. These
tags can be used to add graphic objects to your instrument documents and display
documents.

Operation and Reference
4.1 ICN OPC Server
4.1.1 OPC Tag Database
The database is typically made up of the following:
Devices: These are hardware devices (MOD30 / MODCELL / MOD 30ML) connected to
the OPC Server.
Groups: Tags/Signals can be grouped together into groups. Groups follow a device that
means that you can make groups of tags from a device. In the ICN OPC
database, the grouping will be based on the grouping in the CL block in the
instrument database database.
Each block in the database will be one group and will have the selected attributes of that
block. For example, if you have a block named FIC-100, the group will be called FIC-100
and the signals like PVI, SP, OP etc, will be tags belonging to that group.
Blocks inside a compound will be grouped into a bigger group with name as the
compound name.
Grouping is only for the user’s convenience. If aliases are configured in the CL block for
tags, then the tags will be attached to the devices directly (at the root level).
Tags:Tags define the properties of signals such as address of the signal, group and
device it belongs to, data type and scaling. Examples of tags are PVI, SP, and
OP etc, of a PID block.

4.2 Dynamic Data Entry (DDE) Type Links
The ICN OPC Server supports DDE (Dynamic Data Exchange) for serving data to DDE
Client applications such as Microsoft Excel.
The typical reference for DDE connections is:
Program|Topic!Point
The character between Program and Topic is called a Pipe, the dashed vertical line
character on the keyboard. An exclamation point is used between the Topic and Point.
Refer your application's documentation for using DDE. The following example is for
Microsoft Excel:
=icnopc|’mod30ml’!LICOP
ICN OPC Server
Operation and Reference
In this example, icnopc is the executable filename of the OPC Server, mod30ml the name
that was given to the device in the server configuration, and LICOP is the name given to
the tag.
Excel automatically enclosed mod30ml in quotes. The rule is that if a Topic or Name
contains spaces or special characters, it must be enclosed in quotes.
After entering the valid reference, Excel asks to start the application if it is not already
running.
The #REF! Error value occurs when a cell reference is not valid. In this example, this will
occur if the icnopc application is not found, or if the device name or point name is wrong.
