1.HISTORY
Yokogawa traces its roots back to 1915, when Dr. Tamisuke Yokogawa, a renowned
architect, established an electric meter research institute in Shibuya, Tokyo. After
pioneering the development and production of electric meters in Japan, this enterprise
was incorporated in 1920 as Yokogawa Electric Works Ltd.
In 1933 Yokogawa began the research and manufacture of aircraft instruments and flow,
temperature, and pressure controllers. In the years following the war, Yokogawa went
public, developed its first electronic recorders, signed a technical assistance agreement
for industrial instruments with the U.S. firm Foxboro, and opened its first overseas sales
office (New York).
In the 1960s the company made a full-scale entry into the industrial analyzer market and
launched the development, manufacturing, and sales of vortex flow meters, and in the
decade following established its first manufacturing plant outside Japan (Singapore),
opened a sales office in Europe, and became one of the first companies to bring a
distributed process control system to market.

Yokogawa has sold over 25,000 CENTUM projects in all kinds of industrial plants
worldwide such as oil and gas, petrochemicals, chemicals, power, pulp and paper,
pharmaceuticals, food, iron and steel, waste, and water and sewage treatment. The
majority of the customers are from oil and gas, and petrochemical industries. It means
that once the CENTUM system is delivered and start its operation, it has to be in
operation non-stop.
In the past 40 years of experience, Yokogawa is reputed with the high reliability of the
CENTUM system winning customer satisfactions. Yokogawa is engaged in the global
purchase agreements with world major customers as their sole instrumentation supplier.
Yokogawa needs only one project to convince customers of our capability and win trust.
Once Yokogawa system is delivered, customers stay with Yokogawa.
CENTUM VP is designed based on the concept to keep the plant operation availability
high. Customers expect Yokogawa products to perform its functions without failure so
that the plant operations shall not stop. Yokogawa developed our own FCSs so that we
can meet up with the customers’ expectations. Quite a number of FCSs are still in
operation even after 20 or more years passed since those are originally installed. It is
owing to the high quality of the products themselves that has been supported by the total
serviceability such as skilled manufacturing, quality control, after sales service and
appropriate training.
2.2 Batch Automation

2.7 SCADA Systems: SCADA Hardware - STARDOM FCN
2.7.1 Never Interrupts Your Process
High reliability is essential for the systems that control your critical processes. The dual
redundant capability of the field control node (FCN) autonomous controller ensures that
these processes continue without interruption even when a damaged module is replaced.
CPU unit, power supply unit, fieldbus module, and control network can all be
dual redundant.
Automatic switchover to stand-by CPU.
Automatic data transfer from control side to replaced stand-by CPU.
Hot-swappable modules including CPU.
Fault-tolerant design.
2.7.2 Automatic switchover without interrupting your process
If the control-side CPU fails, the stand-by CPU automatically detects this and takes over
control. To maintain consistency, all process data is synchronized on the stand-by and
control-side CPUs. When a hot-swappable CPU module is replaced, the module
automatically functions as the stand-by CPU by synchronizing both application and
database without interrupting the process. No PC tools are required to perform this
synchronization.
2.7.3 Easy Engineering for Redundant Applications
No special engineering work or dedicated CPU modules are required for redundant
applications. The stand-by and control CPUs also use the same spare parts, allowing
users to keep fewer parts in stock.
2.7.4 Minimize TCO by Minimizing Replacements
Power failure during disc access is a major cause of file corruption in the CPU module.
Without having to replace the entire CPU module, it is possible to recover a damaged file
system by replacing just the FCN system card.

systems with over a million tags. FAST/TOOLS is a powerful, state-of-the-art, flexible,
distributed operations information and supervisory control system. It is a leading package
utilizing the latest best in class IT technology for these applications and is available on a
wide range of industry-standard computer systems.
FAST/TOOLS provide solutions for a wide range of control and supervisory applications
where, for example one or more of the following requirements apply:
• Multiple Process Site environments
• Integration of third party systems
• Wide Area (Media independent) communication
• Robustness for intermitted communication
• Security against unauthorized access
• Disaster recovery and high availability architecture
• Alarm & Event management, Trending & Reporting
These characteristics are often seen in for instance:
• Oil & Gas production and transport, infrastructure, utilities and energy management
• Critical manufacturing applications It also allows the flexibility of combining different
types of systems to provide hybrid solutions, both on new and existing sites (green and
brown field development).Many global industrial companies and utilities rely on
Yokogawa’s SCADA System FAST/TOOLS. The system is used to manage production
processes while guarding availability and efficiency in a way that maximizes return on
investment and minimizes cost of ownership. FAST/TOOLS success, in many of these
critical applications, is based on its highly reliable open architecture design, support of
quadruple redundancy and its on-line configuration possibilities. These properties
contribute to high efficiency and high quality production processes.
MECS,EIE-DSCE Page 24
NBPS
FAST/TOOLS has been developed with a number of key issues in mind, one of which is
the provision of a system that can start small and which can easily grow with short and
long term application needs. This guarantees your investment against premature
obsolescence. Furthermore as a hardware and operating system independent supplier
Yokogawa is committed to the support of standard operating systems, standard network
protocols, standard user interfaces and standard software development tools.
FAST/TOOLS has been developed with over 35 years of experience by combining our
expertise in Supervisory Control And Data Acquisition (SCADA) with requirements
from users and industry leaders. The FAST/TOOLS package is a powerful, modern,
flexible, distributed operations information and control software package. It implements a
Web-based supervisory control human machine interface, OPC server/client functions,
data acquisition from a variety of controllers and devices, alarm management and
historical data management. Furthermore it is a leading system package for operations
control and information integration with business systems and is available on a wide
range of industry standard operating platforms. Many industries and utility companies
with a need for data integration and data integrity use FAST/TOOLS from Yokogawa in
their applications.
FAST/TOOLS is also successful in critical applications due to its very reliable design,
support of redundant and nonstop systems and its on-line configuration capabilities.
These properties contribute to high efficiency and high quality production processes.
FAST/TOOLS has been developed with a number of key issues in mind, one of which is
to provide a system that can start small and which can easily grow with client needs, both
in the short and long term. This philosophy protects against premature obsolescence. The
consequence of being a hardware independent supplier means support of standard
operating systems, standard network protocols, standard user interfaces and standard
software development tools.
FAST/TOOLS provides solution possibilities in a wide range of control execution
applications with the following characteristics:
MECS,EIE-DSCE Page 25
NBPS
• Multiple Process Site environments
• PLC/RTU based control systems
• Wide area communication
• Intensive (mission critical) control performed by subsystems
• Relatively high content sequential (logic) control.
These characteristics are often seen in for example Oil & Gas production and transport,
infrastructure, utilities monitoring and control and high performance manufacturing
applications. It also allows the flexibility of combining different types of systems to
provide hybrid solutions, both on new and existing sites (green and brown field
development).
FAST/TOOLS has a truly User Environment. All the workflow processes, business logic,
and database links were designed after careful studies both technical and ergonomically.
It’s built to work autonomously in a web-based user environment and can be extended
with new applications. Web-based applications can easily access legacy data on other
platforms. Typically interactive, the application accepts input from the web user,
processes the input, and displays the results. Information is stored on BuildLinks’ servers
and the access is obtained via secure logins.
Applications and process information can be rapidly deployed and is easily maintained
centrally on the server. This so called “zero deployment” means that client applications
can be run from any web-browser and the users always get the most recent version of an
application. There is no need to manage licenses and software installations on the client
side and no application files need to be copied over and no communication configurations
need to be setup. Benefits include faster application deliverys increased IT productivity,
and widely accepted technology.
Other benefits of a user environment are:
• Information can be accessed anywhere an Internet connection is available.
• The information is ‘real-time’ (no waiting time for critical information).
MECS,EIE-DSCE Page 26
NBPS
• The information is more secure than it would be on a personal computer.
• Upgrades containing new functions and enhancements are free and automatically
deployed there is no need to manually install software or license keys.
The FAST/TOOLS Web HMI consists of a Web HMI Server and a Web HMI Client
component that can either run separate from the FAST/TOOLS Server or be installed
altogether with the FAST/TOOLS Server environment on a standalone node. Installing
the Web HMI Server on a separate node has the advantage that load can be shared
between the FAST/TOOLS Server and Web HMI Server.
FAST/TOOLS has a true client/server architecture, which is not limited to stand-alone
stations, and allows for distributed functionality. Front-end Servers give the possibility to
reduce the load on the SCADA Server by preprocessing data on remote locations and
passing through only relevant data. Configuration of these stations is stored on the
SCADA Server and is automatically deployed to the Front-end Servers. There is no need
for the engineer to visit the remote locations. SCADA and Front-end Servers can run one
or more I/O-drivers per node, e.g. a configuration could be an application running up to
70 I/O-drivers at the same time on one node, using for example only three network
connections available to connect to the 70 remote PLC/RTU devices. Where system
availability is a prime issue FAST/TOOLS can be configured to run in a redundant
configuration. Several redundancy concepts are available as a standard, illustrating the
flexibility of FAST/TOOLS. Examples are dual or triple server configurations, redundant
networks between the SCADA system servers and clients and/ or between SCADA
system servers and PLC’s, RTU’s, etc. With the exception that Front-end servers can
only be configured as a single server entry.
2.9 STARDOM
The STARDOM is the first system rolled out as a Yokogawa network-based control
system (NCS). An NCS proposes an architecture designed for the e-business era. The
increasingly common business practice of E-commerce provides an environment for
swiftly responding to changes in market demand in many industries. However, these
MECS,EIE-DSCE Page 27
NBPS
industries have now come to require a new system architecture for industrial control
systems. An NCS meets these emerging new requirements and offers high flexibility to
build a superior control system, i.e., a system befitting each user’s purpose.
The STARDOM is an NCS that embodies Yokogawa’s expertise in the industrial
automation market. Reliability, operability, flexibility, scalability, and other keys for
implementing functionality in an industrial control system are all featured in the
STARDOM. The STARDOM allows users to enjoy the merits of important information
technologies such as, Web, Java, and security as part of the system. The use of a variety
of these ITs allows an open system to be configured more flexibly to suit each user’s
intended application e-commerce, supply chain management without having knowledge
of particular systems.
Besides, the STARDOM is a Commercial Off-The Shelf (COTS) system, thus slashing
the total costs of ownership. Also offered by the STARDOM is a new way of operation
and monitoring using a VDS Viewer as the human interface. This means that whatever
the operation and monitoring task, it can be performed anytime, anywhere with a thin
client as a COTS platform. Its control network can be any TCP/IP-based network such as
an Ethernet, fiber distributed data interface, or wireless satellite communication network,
and a variety of communication protocols in the control layer can be combined with the
system.
The STARDOM consists of the following highly independent components:
FCN (an acronym of Field Control Node) is a modulus controller assembled with CPU,
I/O, and other modules as necessary. It supports a variety of I/O modules, has superb
expandability, and can build a highly reliable system with its power supply, CPU, and
control network duplexed.
FCN-RTU (Low power Autonomous controller) is a modulus controller assembled with
a CPU module with built-in analog,digital I/O,communication ports. Up to eight arbitrary
I/O module can be installed (with long base module). FCN-RTU can be used wide
temperature range and high altitude place.
MECS,EIE-DSCE Page 28
NBPS
FCJ (an acronym of Field Control Junction) is an allin-one controller with a built-in I/O
interface, ideal for installing inside machine equipment as well as configuring a
distributed system. Besides, its control network can be duplexed.
2.10 VDS Versatile Data Server Software: VDS is a software package that runs under a
Windows operating system and implements a Web-based human machine interface, OPC
server functions, data acquisition from a variety of controllers and devices, and historical
data management.
Other features include:
• Graphic windows for operation and monitoring, are enabled by HMI server and HMI
client (VDS Viewer) mechanism.
• Object-oriented, COM/DCOM-enabled data sever
• Optionally duplexed network that links autonomous controllers with readily available
Ethernet devices.
• Link with not merely autonomous controllers of the STARDOM but also Yokogawa
FA-M3 controllers and other manufacturers’ controllers
• A wealth of optional packages such as Report Package and Trend Package
• Components practically usable on Visual Studio, including graphic components and
multi-task application development supporting components
2.11 Application Portfolios
Application Portfolios are packages in which many years of Yokogawa’s expertise in
control system configuration are packed, and provide application libraries of broad ranges
of software parts from small parts to those covering an entire plant control application.
Application Portfolios increase efficiency of all engineering stages from designing,
coding, debugging, to startup. In addition to portfolios containing elementary software
parts for control and communication functions, collections of control functions tailored to
a specific process or equipment are offered as Application-specialized Portfolios.

1.P&ID(Piping and Instrumentation Diagram)
MECS,EIE-DSCE Page 33
NBPS
Piping and Instrumentation Diagrams or simply P&IDs are the “schematics” used in the
field of instrumentation and control (Automation) The P&ID is used to by field techs,
engineers, and operators to better understand the process and how the instrumentation is
inter connected.Most industries have standardized the symbols according to the ISA
Standard S5.1 Instrumentation Symbol Specification.
A piping and instrumentation diagram/drawing (P&ID) is defined by the Institute of
Instrumentation and Control as follows: A diagram which shows the interconnection of
process equipment and the instrumentation used to control the process. In the process
industry, a standard set of symbols is used to prepare drawings of processes. The
instrument symbols used in these drawings are generally based on International Society
of Automation (ISA) Standard S5.
The primary schematic drawing used for laying out a process control installation.
P&IDs play a significant role in the maintenance and modification of the process that it
describes. It is critical to demonstrate the physical sequence of equipment and systems, as
well as how these systems connect. During the design stage, the diagram also provides
the basis for the development of system control schemes, allowing for further safety and
operational investigations, such as a Hazard and operability study commonly pronounced
as HAZOP.
For processing facilities, it is a pictorial representation of

2.FUNCTIONAL SCHEMATICS: A carefully planned schematic diagram will
simplify the study and servicing of the equipment. Whereas a conventional schematic
merely shows the electrical components and how they are connected, a functional
schematic will place these parts on the drawing in such a way as to delineate the circuits
they build. It is expanded by considering major equipments as electrical structures built
of circuits, and by treating components as having functions to perform in their circuits.
These points are illustrated with functional drawings. Ideas and techniques are suggested
which can make schematic diagrams more lucid. Below is the P&ID and Functional
Schematics for one pump station.

5.FRONT LOADING AND NEST LOADING
The Yokogawa System consists of a minimum of one field control station and a human
interface system.
In an FCS( Field control station) there are different nodes consisting of different cards to
which the inputs are connected and outputs are taken out after processing. The selection
of cards and the number of cards in each node depends on various parameters.
The selection of these cards and the loading of them in each node taken into account of
all the parameters is called NEST LOADING. It depends on whether the input or output
is digital or analog, voltage or current, coming from a RTD or thermocouple or whether
its a field-bus input etc and the CPU loading.
