Yokogawa offers an intuitive and easy-to-understand HMI environment for plant operation and monitoring, which is the result of
vast experience with CENTUM systems in operation. Flexibility in displaying operation windows and monitors helps in adapting to
various aspects of operation needs. CENTUM VP provides easy-to understand graphics based on the ergonomics and knowledge
engineering. For instance, data displays are provided with high visibility that enables intuitive awareness of the situation. The use
of colors considers the best contrast and environments of the central control room and the configuration of the displays integrates
the knowhow of experienced operators. With all these functions, CENTUM VP enables operators to make quick and accurate
decisions during operations and contributes to improve operation efficiency.
Consolidated Alarm Management Software (CAMS) helps customers avoid safety and environmental incidents that can
be caused by alarm flooding. It also enables customers to improve operational efficiency under normal conditions,
freeing operators from having to perform tedious repetitive tasks and allowing them to focus on true process concerns.
CAMS supports Six Sigma DMAIC (Define, Measure, Analyze, Improve, Control) for alarm management based on the
latest EEMUA #191 alarm management guideline. It provides additional useful tools such as graphical historical data
analysis and automatic alarm reduction. Sequence of event management functions are also included.
With PRM (Plant Resource Manager) and intelligent field devices, operators and maintenance personnel can monitor
the condition of plant assets remotely. Plant Resource Manager's diagnostic functions detect early signs of
performance deterioration such as valve sticking and impulse line blocking. By helping curtail excessive preventive
maintenance and enabling higher level predictive and proactive maintenance, Plant Resource Manager opens the way
to asset predictability.
Optimized allocations of the function keys and buttons enable operators to call up or
switch graphics and control loops by pressing a single key. Two types, a single-loop
and an eight-loop simultaneous operation keyboards, are provided giving users the
ability to react quickly to process conditions.
Continuously displays the latest alarm
messages, keeping operators up to date on
process conditions.

AOG Solution
The AOG (Advanced Operator Graphics) solution
emphasizes ergonomic design and seeks,
through improved color selection, layout, and
visual function, to improve operators situational
awareness. A team of Yokogawa engineers
visited many plants to conduct a detailed
analysis, review the tasks carried out by
operators, and learn about the plant's operations.
In accordance with general principles on industrial
design and human engineering, Yokogawa then
redesigned the GUIs for the HMI displays to
reduce operator errors, make their work easier to
perform, and reduce physical stress.

All plant process data and device data are
handled by CENTUM VP.
CENTUM VP's versatile architecture covers not only continuous and batch process control but also
manufacturing operations management.
A wider variety of software suites for automation solutions is available.

5. Control
Control network
I/O network I/O network
Yokogawa’s CENTUM series achieves high availability thanks to a dual-redundant
design, online maintenance capability, and other advanced features. The FCS
processor module, power supply, I/O modules, and I/O networks are all dual
redundant. Active and stand-by processor modules work in synchronization: even if a
failure occurs, control switches over seamlessly to the stand-by module and the FCS
continues running. Failed modules can be replaced online, ensuring that not even a
hardware failure will interfere with plant operation.
Ensuring the Highest Availability and Reliability
The CENTUM series employs a pair & spare architecture
that improves the stability of process control. Each
processor module has redundant CPUs that execute the
same computations simultaneously. Their outputs are
constantly compared and a bump-less switchover to the
stand-by processor module is initiated if any anomalies
caused by electronic noise or other phenomena are
detected. This minimizes the likelihood that CPU hardware
faults will have any impact on process control.
The HIS runs on Microsoft Windows operating systems
platforms and offers customers the convenience of using
commercial-off-the-shelf hardware. Although the reliability of a
PC is relatively low, it does not affect the total reliability of the
process operator function. As the HIS is not server-client
dependent, multiple HISs provide independent backup such
that there is no single point of failure.
Through an online maintenance function, FCS applications can be modified without shutting down the FCSs. It means, you can change
logics and parameters without interrupting the process control. This is useful for expansion or modification of the plant in operation.
Yokogawa has a long history of delivering stable and high quality
CENTUM systems. The CENTUM VP controller features outstanding
processing performance and a large application storage capacity, yet
inherits the same quality and stability that are the hallmark of the
CENTUM series. It has been optimized to take full advantage of
advances in field digital technology that will help plants operate with
increased efficiency and stability.
The state-of-the-art Field Control Station (FCS)
Designed for Stable Control
Online Maintenance
The CENTUM VP provides functional blocks for monitoring, control, manipulations, calculations, logic functions, and sequences. Not
only continuous control but also advanced control, complicated sequence control, and batch control are all executed in a redundant,
secure, and reliable controller environment. Plant systems can be flexibly designed, ranging from small-to-large-scale, through the
combination of these control blocks.
Yokogawa's Vnet/IP provides open, reliable, and real-time
broadband communications, which enables the use of commercial
off-the-shelf technology that help reduce costs. The open

6. Engineering
Yokogawa accelerates plant startup and
Ensures sustainable performance
The Automation Design Suite - Improving Quality, Reducing Complexity and
Enhancing Productivity
Yokogawa paves way for a new engineering paradigm for the next-generation. It is
not uncommon for a project to experience backsliding and significant rework, all of
which affects the TCO (Total Cost of Ownership). Yokogawa's engineering prevents
these inefficiencies and ensures our customers reap all these benefits throughout a
plant’s lifecycle.
Yokogawa provides smart engineering thanks to three innovative products.
● Automation Design Suite, Yokogawa’s engineering environment
● N-IO (The Network I/O), Yokogawa’s software configurable smart I/O
● FieldMate Validator, Yokogawa’s commissioning tool for N-IO
The Automation Design Suite adopts a Modular approach to
automation design and execution, where process loops, alarm
design philosophy, graphics and more are deployed as design
patterns: downloaded, shared and re-used as standards across the
enterprise, saving time and resources.
Yokogawa leverages its long history and vast expertise in process
automation, with standardized, industry proven engineering
modules available that span a broad range of processes and
functions for production, safety and asset excellence.
After the DCS is sent to a site, design changes often happen due to physical restrictions of implementation or inadvertent
miscalculations and these changes can significantly affect the project schedule. And shortening the term of a project is an everpresent
challenge. Flexible I/O binding, Yokogawa’s improved late I/O binding solution, helps overcome these customer challenges.
The Automation Design Suite, Yokogawa's new engineering environment, retains the entire engineering history of your plant from
design phase, through commissioning and live operation; which ensures up-to-date plant knowledge with every expansion, or
hardware and software change throughout your lifecycle.
The flexible I/O binding facilitates simple and hassle-free I/O binding. This is made possible by software marshaling
and the N-IO’s universal channels. The type of I/O and the interconnection between the I/O module and the controller
can be modified remotely which significantly absorbs the impact of last-minute I/O changes. Furthermore, the flexible
I/O binding achieves early delivery of I/O cabinets to the site, and problems can be found and fixed on-site at a very
early stage.
10 11
Flexible I/O Binding – ensuring project execution excellence
Reducing the Risks to Scheduled Project Delivery
The flexible I/O binding shortens duration of a project. After I/O design is fixed, application engineering and hardware
engineering can progress independently and parallel. This is made possible by System Independent Loop
Commissioning. System Independent Loop Commissioning project capability utilizes Yokogawa's FieldMate
Validator, an innovative tool allowing the field testing and validation of N-IO without requiring a deployed system.
