NTPF100 Exaopc

OPC Interface Package

GS 36J02A10-01E

nGENERAL

As data sharing between information systems increases, the requirement to eciently access and use plant information to meet business needs in a timely manner also increases. Within the process industry, the control room contains valuable information that has previously been inaccessible. Exaopc was created to provide an open OPC

interface bridge between the control room and the outside world.

Exaopc is an OPC server running on a Microsoft Windows platform which can be connected to a variety of PCSs

(Process Control Systems) providing OPC clients with process data and alarm events.

This GS contains the specication for the Exaopc OPC Server Interface Package.

nFUNCTIONAL SPECIFICATIONS

Exaopc supports the following OPC specications:

l Data Access (DA) Server Function

The DA Server reads and writes process data using item IDs as identiers.

l Historical Data Access (HDA) Server Function

Exaopc automatically saves instantaneous values acquired from the DA Server and A&E Server, to an HDA historical

database. The OPC client can access historical data by rst connecting to the HDA Server.

l Alarms & Events (A&E) Server Function (*1)

The A&E Server provides alarms and events from plants that occur asynchronously. The following messages are

available from Yokogawa CENTUM Integrated Production Control Systems:

- System alarm messages

- Process alarm messages

- Mode/status change messages

- Sequence messages

- Operation guide messages

- Engineering maintenance messages

- Operation record messages

- Server internal errors

*1: A&E server supports the following Alarm Management functions of CENTUM VP.

- Exaopc R3.72 or later supports for “Consolidated Alarm Management Software (CAMS) for HIS”

- Exaopc R3.78.10 or later supports for “Unied Alarms and Conditions Server (UACS)”

l Batch Server Function (*1) [VP Batch, CS Batch 3000]

The Exaopc batch server function (Exaopc/Batch) reads and writes batch data and its related information with VP

Batch and CS Batch 3000.

*1: OPC client is dedicated to Exaquantum/Batch.

l OPC Security Interface

Exaopc provides security by using an OPC Security-compliant interface whenever an OPC Client uses the DA, A&E, HDA and/or Batch servers.

nFEATURES

l Major Applications

The Exaopc OPC Interface can be used in a wide variety of OPC client applications.

- Yokogawa packages, including Exaquantum PIMS and Exapilot (Operation E󰀩ciency Improvement Package)

- OPC standard compliant general-purpose applications

- User applications

l Compliance with OPC Specications

The Exaopc package supports OPC standard interface functions (DA/A&E/HDA, Batch, Security) specied by the

OPC Foundation, and additional functions such as data item browsing.

l Connectivity with CENTUM Systems

Exaopc can be connected to Yokogawa CENTUM VP/CS 3000.

l Automatic Backup

The process data acquired by the DA server is automatically saved and stored in the historical database as backup data. Access to the stored data is enabled by the HDA server function.

l Equalization [CENTUM VP/CS 3000]

A list of tags in CENTUM can be equalized by Exaopc. When function blocks (tags) are added, deleted or changed in

the FCS (Field Control Station) builder and they are loaded, a change notication is sent to Exaopc. Exaopc will then

update function block data based on the received data.

l Browsing [CENTUM VP/CS 3000]

Users can view the content of the OPC server from OPC client. The OPC client can access CENTUM tag list Exaopc acquired by Equalization functions.

l CENTUM Security [CENTUM VP/CS 3000]

Exaopc security (account, scope of monitoring, operation ID, operator console group and access level) is dependent on the CENTUM.

l Tra󰀩c Control

When an OPC client attempts to access a large volume of data from a CENTUM system loading problems may occur (load concentration on control stations and control buses, in particular). To prevent problems, access from OPC clients are restricted to avoid the maximum accessible data rate being exceeded.

l Expanded Test Functions [CENTUM VP/CS 3000]

By connecting to the Expanded Test Functions on CENTUM VP/CS 3000 users can access the FCS simulator on a station with CENTUM VP/CS 3000 engineering functions. Therefore, users can perform engineering and testing OPC

clients without using actual FCSs.

l Multiple Project Connection [CENTUM VP/CS 3000]

On Exaopc, users can use Multiple Project Connection functions for CENTU VP/CS 3000, which enables integrated monitoring of multiple projects. This allows users the ability to handle CENTUM VP/CS 3000/CS project data on

Exaopc as well as the data from their own project.

To use these functions, the supervisory CENTUM VP/CS 3000 system requires a Multiple Project Connection

Package.

Function specications, restrictions, and the operational environment for these functions are the same as for CENTUM VP/CS 3000.

l Viewer Function and Tool Function

These functions provide various kinds of viewer and tool to check and monitor Exaopc operation status.

Software Conguration Viewer, Station Viewer, OPC Connection Conrm, Exaopc Server Monitor

l IT Security support

A user can select suitable security level out from standard and legacy types. This IT security level is common through Yokogawa system products, and Exaopc is able to have the same IT security as CENTUM system.

l Exaopc Product Security Function

In order to tighten the security for accessing the CENTUM system, access to the CENTUM data is blocked until after the user authentication is done by logging on to the OPC client.

l Solutions for Redundant Exaopc

Exaopc provides two solutions with additional function that enhance its availability in case of its failure. Please contact Yokogawa for additional information.

- Two Exaopc stations are congured and Exaopc-RD switches OPC connection in client PC automatically, please refer to “Duplicated OPC Server Conguration”.

- Exaopc can run on the two computers that make up the redundancy conguration, please refer to “Dual-redundant

Platform for Computer (Exaopc R3.77 or later)”.

nSYSTEM CONFIGURATION

l Server/Client Composition

The following two client/server congurations can be used:

- The OPC client exists on a PC with Exaopc installed.

- The OPC client exists on a supervisory computer (Windows PC).

Only one Exaopc can be installed in one PC. Two or more Exaopc can not be installed in one PC.

l Multiple Clients

A single Exaopc can be accessed from multiple OPC clients.

l Multiple Servers

Users can access multiple Exaopc’s from a single OPC client.

l Duplicated OPC Server Conguration

Exaopc-RD (installed on the OPC client machine) supports OPC Server redundancy by monitoring two Exaopc
