DCS Offerings

Centum, Stardom NCS

DCS Business

Yokogawas CENTUM system has always been at the core of the

companys DCS business. The latest version of Centum is Centum

CS 3000 R3, which is the sixth generation since the introduction of

the first CENTUM system in 1975. The company currently

supports six versions of Centum. Many Centum V systems, for

example, are still operational and supported by Yokogawa, who

guarantees support of all its control systems for up to 10 years

after sales of new systems are discontinued.

Centum CS 3000 R3 is a major upgrade over the R2 version, and

integrates advances in information technology with the rapidly

evolving needs of the modern manufacturing environment. Key

features of Centum CS 3000 include Windows 2000 HMI,

Fieldnetwork I/O, native Foundation Fieldbus (FF) functionality,

and a series of advanced functions such as embedded advanced

control and Plant Resource Manager (PRM). The R3 version is also

backward-compatible with older CENTUM versions and is easily

upgraded in phases or replaced with minimal investment.

Yokogawas Centum CS 3000 R3 field network I/O, developed in

conjunction with Fuji Electric. The new I/O incorporates an

Extended Serial Backboard (ESB) Bus with a speed of 128 MBPS.

Centum CS 3000 R3 also incorporates a high-speed Ethernet-

based control network. At the fieldbus level, CS 3000 R3

incorporates a Foundation Fieldbus H1 I/O card.

The advanced functions of CS 3000 R3, however, provide the true

value add. The first of these is integrated Foundation Fieldbus

engineering with Yokogawas Plant Resource Manager (PRM)

software. PRM is Yokogawas plant asset management (PAM)

solution. In ARCs view, providing integrated PAM functionality is

a key part of any effective Foundation Fieldbus Solution.

CS 3000 R3 also includes a new control platform, called Advanced

Process Control Station (APCS). Through Yokogawas alliance with

Shell Global Solutions, Shells SMOC advanced process control

software has been embedded in the CS 3000 control architecture.

Yokogawas answer to incorporating open networking technology

in its systems comes with the release of the Vnet/IP control

network, which is available in the latest major version release of

the CENTUM CS 3000 control system. The first widely available

DCS control network based on Gigabit Ethernet, Vnet/IP offers

redundant communications and communications band partitioning

over standard Ethernet, while providing the high reliability and

deterministic response required for process automation. Vnet/IP

offers ten times the throughput of Vnet, and routers are available

that can switch between Vnet and Vnet/IP.

The openness of Vnet/IP makes it easier for users to connect non-CENTUM components to the control network through Vnet/IPs

TCP/IP communications capabilities and enables their network

configuration with commercially available network equipment.

Data from third-party devices can be integrated with CENTUM CS

3000 through the GSGW process data server on Vnet/IP.

Since Vnet/IP is Ethernet-based, users have the ability to choose

from a wide range of hardware, and Yokogawa does not specify

which hardware vendors are to be used. Yokogawa has, however,

certified and tested Cisco and Dell hardware for Vnet/IP, which is

consistent with the Ethernet-based offerings of many other DCS

suppliers.

Yokogawa Stardom Network Control System

Yokogawas Stardom Network Control System (NCS) addresses the

needs of applications where the combination of a PLC and HMI

package are often used, but found to be inadequate. With the

release of Stardom, Yokogawa is addressing the needs of markets

that traditional DCSs have not yet met. Many of these, if

automated at all, have used a variety of technologies ranging

from PLCs to PCs that have required significant effort for systemcomponent connections. By leveraging the Internet and internet

technologies, these types of applications can be addressed more

effectively with fit-for-purpose configurations. Stardom NCS is the

system that will fully realize Yokogawas e-RM vision for

collaborative manufacturing.

Yokogawa Releases Enhanced Version of STARDOM Network-

based Control System

In April of 2008, Yokogawa released an enhanced version of the

STARDOM Network-based Control System that complies with USgas industry standards and provides a new data-logging function

for the FCN/FCJ autonomous controllers. These enhancements

reduce costs by improving the efficiency of both operation and

maintenance. Yokogawa will

use the release of this

enhanced version to

strengthen its sales targeting

the oil and gas upstream

processes.

The enhanced STARDOM

version supports the

American Gas Association's

AGA3, AGA7, and AGA8

standards used in North America, South America, and Asia. This

ensures correct flow measurement as gas is transported between

drilling companies and distribution companies. STARDOM

provides both gas metering and control functions.

The FCN/FCJ autonomous controllers have been enhanced with the

introduction of a new data logging function. The controllers can

now store control data and data from field instruments and

facilities for access from distant locations via the Web, enabling

efficient remote monitoring.

The STARDOM engineering tool has been enhanced with network

templates that improve the reusability of applications. Yokogawa

provides samples of these network templates. The engineering

tools for STARDOM's FCN/FCJ autonomous controllers will also

support Windows Vista.

Vigilance Campaign

Yokogawa has come a long way in making its message clear to

the world of process automation. Several years ago, the company

embarked on a full-scale global marketing campaign to make

customers aware of Yokogawas focus on system reliability,

security, dependability, and robustness.

Dubbed Vigilance, the campaign created a unified message for

the company and greatly helped expand awareness of the

Yokogawa brand and corporate philosophy. Vigilance is

successfully increasing brand awareness and communicating

Yokogawas message of reliability and quality to the worldwide

market, particularly outside of Japan.

While the Vigilance campaign successfully expresses the

companys philosophy, articulating the value proposition of the

companys product, application, and services offering remains a

key challenge for the company. Yokogawa, for example, has long

been known for its control systems, field instrumentation, and

fieldbus capabilities. Many customers, however, remain unaware

of Yokogawas capabilities in production management, safety

systems, alarm management, plant asset management (PAM),

and many other areas. Yokogawas ongoing Vigilant-Plant

campaign is designed to raise customer awareness of Yokogawas

solution set and where it fits in the Vigilance scheme.

The VigilantPlant philosophy eliminates unplanned downtime and

allows businesses to adapt and change quickly and with agility, to

shifting market conditions and customer demands. This is

consistent with ARCs view that giving personnel access to the

right information at the right time combined with the ability to

take action is crucial for achieving OpX, and is the foundation of

real-time performance management (RPM).

CENTUM Release 3.08

Yokogawa announced CENTUM CS 3000 R3 Release 3.08 in

October of 2007. Key features of the new version included

enhanced gateway functions that provide enhanced connectivity

with competitors' DCSs and PLCs and a Consolidated Alarm

Management Software (CAMS) offering, which Yokogawa claims is

the first true CAMS-based approach available in the industry.

Yokogawa's gateway functionality is embodied in the System

Integration OPC Station (SIOS). Enhancements to the gateway

mean that operators will be able to control and monitor both DCS

and PLC systems from Yokogawa competitors with the same look

and feel as CENTUM CS 3000. Data linkage to Yokogawa's

STARDOM system has also been enhanced.

The CAMS alarm management package for the CENTUM CS 3000

Human Interface Station can integrate and control alarms fromCENTUM CS 3000, the ProSafe-RS Safety Instrumented System,

Plant Resource Manager (PRM), and STARDOM systems. CAMS for

HIS collects alarms and events from each system, identifies

expressions, and eclipses duplicate alarms. This package also

provides value-added alarm information such as priority level,

sorting identifier, root cause, and action to be taken. It helps

reduce alarm flooding that may cause critical plant problems and

relieves operators from cumbersome alarm acknowledgement

tasks to let them concentrate on controlling and monitoring the

process.

Yokogawa Unveils Centum VP

CENTUM VP is the eighth generation of the CENTUM series, and

succeeds the CENTUM CS 1000/CENTUM CS 3000. While securing

clear backward compatibility and consistency with previous

CENTUM systems, CENTUM VP redefines the role of a production



6/8


control system, commonly known as a DCS. Going beyond the

traditional DCS function of controlling and monitoring a plant,

CENTUM VP integrates plant information management, asset

management, and operation support functions, achieving a unified

operating environment. CENTUM VP provides a foundation for

operational excellence by delivering information in context and

allowing easy role-based access to all key information.

The first major component of the system, released in May of 2008,

was the Centum VP HMI, which is one of the first HMI applications

for automation to be available in Windows Vista and Windows XP.

The new HMI incorporates a universal color scheme, greatly

reducing the chance of an operator misinterpreting information

due to color blindness, and increasing the overall visibility of the

most important information to the end user. Yokogawa did a lot ofresearch into this HMI to drive increased productivity and

decrease the chance of operator error. Yokogawa claims that the

new HMI "more than doubles the speed of operational decision

making." The HMI also offers integrated alarm management

capabilities, faceplates, trends, and history windows.

Centum VP Release R4.02.30

The latest release of Centum VP supports integrated ISA 100

wireless functionality. These wireless products include an EJX-B

series differential pressure and pressure transmitter, a YTA seriestemperature transmitter, and an integrated field wireless gateway

for field sensor networks.

Yokogawa Releases Enhanced Version of STARDOM Network-

based Control System

Yokogawa Electric introduced an enhanced version of the

STARDOM Network-based Control System in 2010 with upgraded

engineering functionality. The new engineering tool facilitates the

construction of field digital communications networks that can

reduce the cost of maintaining production equipment distributed

over wide areas.

For this latest STARDOM version, Yokogawa has optimized its

existing engineering tool that is used to configure large-scale

SCADA systems based on Foundation Fieldbus. The new



7/8


Foundation Fieldbus Configurator enables a 60 percent reduction

in engineering man-hours.

Improvements have also been made in STARDOMs Logic

Designer engineering tool for creating control applications. An

enhanced Distributed Network Protocol 3 (DNP3) is also provided.

All screens now have the same look and feel as that of other

STARDOM engineering tools. An enhanced export and import

function facilitates repeat engineering. Application downloading

time to fieldbus devices have also been reduced substantially.

Improvements have also been made to the Control Application

Creation Tool (Logic Designer). New drag & drop, automatic

rearrangement, automatic wiring mode switching, and other

functions have been added that make this software easier to use.

Enhanced Functionality of DNP3 Protocol

DNP3 is a communication protocol used for controlling equipment

distributed over a wide area, such as oil and gas field equipment.

The protocol has been enhanced to support a wider range of

SCADA applications.

Support of Modular Procedural Automation

As a major supporter of Modular Procedural Automation and the

procedural automation standard, Yokogawa already has a toolset

that can support Modular Procedural Automation (MPA), fromapplications as small as scheduling sequences consisting of many

sequential function charts (SFC) steps to more complex and

integrated multiproduct solutions incorporating the Centum VP

process automation system. SFC is the desirable means of

defining the state relationships, concurrency, and transition

conditions otherwise known as the state model of the process

in the control system. With the application of additional

procedural programming, the state model itself becomes the root

of the control system.

The primary tool that Yokogawa has to implement MPA in the

continuous process industries, however, is Exapilot an automated

procedural control solution now installed in over 1,000 plants

around the world. Using Exapilot to describe steady state and

non-steady-state operations by experienced operators as a

graphical flow diagram of the sequence of actions, the operations



8/8


can be fully- or semi-automated. In addition to Exapilot, the

Exaplog event analysis package helps to refine the controllability

of a plant and identify parts of the plant operation that could be

improved, by analyzing alarms and operator actions side by side.

Combining Yokogawas consulting skills with products such as

Exapilot allows users to integrate operator actions and the control

system into a single unified environment for best practice plant

operation. Some operators have a lot of knowledge, but are not

familiar with computers or Exapilot, so someone has to put this

knowledge into Exapilot. Yokogawa knowledge engineers

specialize in capturing this knowledge from experienced workers

and driving it into the system.

Key Industries

While Yokogawa traditional strengths have been in thepetrochemical, refining, oil and gas, and chemical industries, the

company plays across all process industry segments, particularly

in its native Japan. The company has also been making a

strategic push into the power generation industry and was won

several large power generation projects over the past year.
