1. Description

1.1. Overview

OPC (OLE for Process Control ) is an industry standard for transferring process and event data between a server and one or more client applications.

The OPC Server provides an OPC link between a Trusted Using Ethernet Interface cards within the server’s host PC, it connects to one or more Trusted Controllers. OPC client applications can connect to the server using Microsoft COM ( or DCOM over a network ). Each client can browse the server to view the available tag references. Using these references, the clients can then arrange for groups of tags to be synchronously updated at defined intervals. Values may also be written asynchronously to the server.

Figure 1 shows how the OPC Server fits between the Trusted OPC client applications.

System and one or more OPC clients.

System hardware and one or more

1.2. TrustedTM OPC Architecture

The server can be divided into four main functions: The Browse Interface, the OPC Data Access Interface, the OPC Alarms & Event Interface and the Communications Interface.

1.2.1. The Browse Interface

The server provides a list of tag references that OPC clients can browse in a standard manner. The root node is the Trusted as sub-items. Selecting a controller in the tree will show a list of its tags in a window to the right.

Figure 2 shows an example browse tree structure. If Controller # 1 is selected, and then a tag on the right is selected, the path would be:

Ethernet Interface. All controllers defined from ‘Edit/Controllers’ are shown

TrustedTM Ethernet IF

Controller # 1

Controller # 2

Figure 2 Example Browse Tree Structure

TrustedEthernetIF.Controller1.<Tag>

Where <Tag> may be a controller level tag or a further hierarchical path to a data point.

1.2.2. OPC Data Access Interface

When an OPC Data Access client attaches to the server, a unique server object is created within the main server application. The client can create and edit groups within this server object. Each group has a number of tag references and an update rate. Every time the tags are to be updated, the server will inform the client of the new values, quality, time, etc.

See the specific OPC Data Access client documentation for further information.

1.2.3. OPC Alarm & Event Interface

When an OPC Alarm & Event client attaches to the server, a unique server object is created within the main server application. Each time an event occurs, the server informs the client of the event. Event information includes the tag name, value, time the event occurred, etc.

See the specific OPC Alarm & Event client documentation for further information.

Issue 23 April 10 PD-T8030S 12

TrustedTM OPC T8030S

1.2.4. OPC Data Access vs. OPC Alarm & Event

OPC Data Access and OPC Alarm Event clients are based on separate OPC standards. While some OPC clients support both standards within the same package, most OPC clients will support one or the other. OPC Data Access clients are the most common, and are used by many MMI (Man Machine Interface) packages to monitor specific process variables originating from a Trusted

system. OPC

Alarm & Event clients are used primarily in “Event Historian” or “Event Log” type applications.

OPC Data Access clients query the server by tag name. They can query the value of a specific tag, create groups of tags which will be updated at regular intervals, subscribe to a tag to receive updates when that tag’s value changes, or change the value of the tag in the Trusted

controller. The server allows Data Access clients to access any Controller tag that either has a communications address or is configured for Sequence of Event or Process Historian updates.

OPC Alarm & Event clients query the server by controller name. Instead of being able to query by tag name, the Alarm & Event clients receive all events originating from subscribed controllers. The server will generate events only for tags defined by a Controller that are configured for Sequence of Event updates.

1.2.5. Communications Interface

The server manages all OPC client queries, updates, polling groups, and subscriptions. The server translates these requests into a combination of both polled and event updates, which are sent to the appropriate Trusted know about or need to understand the specific communication details between the server and the Controllers.

2. Installation and Configuration

2.1. ‘Log on as a Service’ privilege

The server runs as a Windows service. This means that it has no application window, it does not appear on the taskbar and it cannot be started using an icon. However, it is able to run even when no users have logged in and can automatically start on boot up without needing a user to log in.

Before installing the OPC Server, a user may be given privilege to start an application as a service. Choose a user with Administrator privileges. If the service is to start in the local system account, then a separate privileged user is not required.

Versions of the OPC Server before 102 operate as executable programs within the user login, and do not need a service privilege. Starting and stopping these versions requires the program to be stopped and restarted. The configuration functions described here are available from the server program itself.

2.1.1. Windows 2000 and XP

Click Start | (and Settings on 2000) Control Panel | Administrative Tools | Local Security Policy.

In XP, ‘Administrative Tools’ may also appear on the Start menu, or may have been disabled. To enable this, right click on ‘Start’ and select Properties. In the ‘Start Menu’ tab, click Customize. In the Advanced tab, scroll down the ‘Start menu items’ to the bottom and select to display ‘System Administrative Tools’.

If the Control Panel is arranged in categories, in the Control Panel ‘Pick a category’ view, select ‘Performance and Maintenance’ and then Administrative Tools. Select ‘Local Security Policy’.

In ‘Local Security Settings’, select ‘Local Policies’. Select ‘User Rights Assignment’. Double-click on ‘Log on as a service’. The Properties window shows the users that are allowed to start a service.

If the chosen user does not appear in the list, add the user by clicking ‘Add’ (2000) or ‘Add user or group’ (XP). In XP, clicking ‘Advanced’ and ‘Find Now’ displays all available users.

TrustedTM OPC T8030S

2.2. Installing the OPC Server

The Trusted is accomplished by running the setup program on the installation CD, which will run automatically if Autoplay is enabled.

In addition to the OPC Server, the setup program will install a number of files required for OPC. The setup program also updates the registry to allow OPC clients to browse for and connect to the server.

Windows versions NT, 2000 and XP require administrator privileges in order to complete the installation. Windows NT installations require Service Pack 4 or higher. Basic configuration consists of telling the OPC Server which Controller to connect to, where to find its symbol database, and how fast to poll the controller for updates.

The installation program offers the option of a full installation, which includes the OPC Server, and ‘Remote Configuration Program Only’, which only provides the configuration tool and not the OPC Server.

The installation program allows a specific username to be used to run the service. If the service is to run under the local system account, there is no need to enter a user and password. If a specific user is required and was given the privilege in section 2.1, enter the username and password.

The installation will ask for the serial number supplied with the package on a label, as shown in Figure

3. Enter the serial number and attach the label to the PC on which the OPC Server is installed.

OPC Server must be installed and configured before OPC clients can use it. Installation
