1 1.1 Introduction 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.
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.
2 2.1 Installation 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.

3 3.1 Application Tutorial 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.

4 4.1 Operation and Reference 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.
ICN OPC Server Operation and Reference Figure 4 .1. OPC Server Tag database Having a .MIF file is very handy. Connecting the MIF file to a device in the OPC tag database will create the groups and signals automatically. This will save a tremendous amount of time compared to creating them manually. 4.1.2 ICN Device Properties Configure the properties of the MOD30 or MODCELL or MOD 30ML device in this dialog. Figure 4 .2.
ICN OPC Server Operation and Reference Timeout: Timeout value in ms is the time for which the OPC server tries to reestablish communication with the device in the case of a communication failure. The default value of 1000 ms should not need to be changed. Address: Type the instrument’s ICN address in the address field. Interface File: MIF file - Choose the Modcell Interface file for this device: To choose a .MIF file, 1. Click on the button next to the MIF File field on this dialog box.
ICN OPC Server Operation and Reference Figure 4 .3. ViZapp Communication Setup Simulate I/O: The OPC Server does not access the device in Simulate mode. When checked, no communication takes place and I/O values are generated randomly. 4.1.3 Serial Port Configuration Configure the serial port for the communication: Menu item Edit – Ports displays the communication port settings as shown below: Figure 4 .4.
ICN OPC Server Operation and Reference • Select the COMM port from the drop-down menu in the Port field and then enable it by checking the box next to the Enable field. • Choose the Baud Rate, Parity, Flow Control, Data bits and Stop bits from this dialog box.

See the Scaling section for details.
ICN OPC Server Operation and Reference 4.1.5 Saving the OPC Server Tag database: The OPC tag database can be save as a file with an extension. ICNS. • Menu item File – Save will save the OPC Tag database. • The Save As dialog box will be displayed next as shown below: • Choose the same folder where you have saved the instrument database for saving this file and then type a name for the OPC tag database file in the File name field. • Click on the Save button to save the file.
ICN OPC Server Operation and Reference • Live data values from the instrument will be displayed in the Value column of the OPC Server application. • The live data is read-only as this OPC client application and is mainly used for testing the function of the OPC Server and the communication between the hardware devices and the OPC Server tag database. It does not allow writing of the same. 4.1.
ICN OPC Server Operation and Reference 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.
