Process automation end users are under more pressure than ever to do more with less. The current economic climate means that many automation capital projects are on hold. With capital budgets tighter than ever, users instead focus on operational budgets (where cost cutting is also a key concern), or on automation investments with a very rapid return on investment.
Alarm management is not just a project that has a start and end date; it's a continuous cycle. Once the alarm system has been reviewed and improvements have been identified, we must check that controls are in place to ensure the alarm system remains functional. The key is to ensure that the system is continuously monitored and any changes are fully documented. There are seven key steps for alarm management. Rationalization is one of those critical steps.
This technical white paper will discuss Yokogawa's CENTUM VP DCS (Distributed Control System) product, hereafter referred to as "CENTUM VP", and the extent of its compliance with Part 11 of Title 21 of the Code of Federal Regulations, (21 CFR Part 11), the Electronic Records / Electronic Signatures Rule.
FOUNDATION™ Fieldbus is an enabling technology with the potential to revolutionise operation and maintenance in the process industry and thereby to contribute significantly to reducing these costs, everyday of the lifetime of a plant. Specifically with regard to maintenance, FOUNDATION™ Fieldbus opens the way to proactive diagnostics and to virtually eliminating preventive maintenance and to avoiding shutdowns.
The worlds of process automation and production management have been converging for some time. What once used to be islands of automation and production management functionality connected through highly proprietary integration schemes that were costly to maintain have developed into integrated platforms that provide seamless data exchange between the world of automation and the plant floor, the functions of production and operations management, and integration with business level systems.
Network-IO can help reduce projects by decreasing the amount of time needed to implement the physical part of the process control system. A system with configurable I/O allows flexible "binding," in which the soft- ware configuration of the system can be loaded into the physical system at a late stage in the project.
Recently, several ARC Advisory Group analysts and management team members had a chance to sit down with the new Yokogawa President and COO, Mr. Takashi Nishijima, and several other top Yokogawa executives to discuss the company's burgeoning presence in the worldwide upstream and midstream oil & gas industry.
In today's dynamic industrial marketplace, the only constant is change. Raw material costs, energy costs, market demands, environmental and safety regulations, technology, and even the nature of the labor force itself are constantly changing, and not always in predictable directions.
Network and system security is now a necessity in process automation industry. YOKOGAWA provides a service lifecycle solution for cyber security to ensure that the security measures and deployments are continuously enhanced, monitored and inspected.
This white paper explains the details of the security design, implementation, operation and validation solutions from the technical perspective.
As plant operation becomes more intelligent and complex, the alarm system for safe and stable operation is becoming increasingly important. An alarm warns operators of an abnormal situation in a process and urges them to respond to it.
Recently, there is an increasing demand for operation and monitoring of all the various controllers distributed in the field on the same screens to improve plant operation efficiency. The purpose of the Unified Gateway Station (UGS) is to connect external controllers, such as the STARDOM's FCN/FCJ autonomous controllers and other vendors' controllers, to the CENTUM VP integrated production control system and to operate and monitor those external controllers on the Human Interface Station (HIS) screens, the operation and monitoring screens for the CENTUM VP.
The specifications of the ISA100.11a wireless communication standard of the International Society of Automation (ISA) for industrial automation were published, and companies are developing products based on the standard. The ISA100.11a has many features such as high reliability including redundancy, network scalability, and support for various protocols for industrial automation.
To improve efficiency and quality in the DCS application coding and inspection phases for an entire CENTUM CS system, engineering tools have been developed, along with the training required to operate these tools. In consideration of the time needed for development, the need for adequate operability, the basis of standard CS software architecture, and the use of freeware (e.g., Perl2 and Tcl/Tk3), we began development of these engineering tools with the objectives to reduce development costs and increase efficiency.
A fieldbus is a bidirectional, multidrop, digital communication system developed to replace the conventional 4-20 mA communication lines that connect intelligent field devices with a control system. Fieldbus is continually reviewed in an effort to standardize the fieldbus specifications to comply with the specifications of the IEC and ISA.1
The first stage in creating next-generation production control system that achieves innovative plant operation is providing "Visualized operation". "Visualized operation" for the customer means that he can reliably access and visualize plant data regardless of plant location and time.
One of Yokogawa's corporate philosophies is to contribute to society through broad-ranging activities in the areas of measurement, control, and information. To achieve this philosophy in the control industry, Yokogawa launched CENTUM, the world's first distributed control system (DCS), in 1975.
As the world's societies become more connected, market competition is becoming more ruthless and transactions are performed at ever increasing speeds. Deregulation has ignited global competition throughout the world. The proliferation of Information and Internet technologies have accelerated the growth of global competition, with life cycles for high tech products having lives measured in "dog years" (in each normal year they advance seven years).
The consolidation of control rooms was conducted in several refineries in the 1990s and early 2000s as a means of reducing the number of operators and improving the efficiency for enhancing competitiveness. The characteristics of consolidated control rooms vary, reflecting the history of a refinery.
The manufacturing industry has grown based on solid production technologies for creating quality products. However, the economic environment is changing dramatically, forcing manufacturing firms to face tough global competition; firms must ship the right products at the right time as the market requests.
The phenomenon of the current era, coined the information age, involves a global trend toward digital technology and open architecture. Field devices are no exception to this trend.
For large scale geographically dispersed projects, there may be a hierarchy of individual Process Automation systems, which in turn are each responsible for a specific region, and are managed by a higher level system. Engineering of systems on this scale is a huge challenge, because each individual system has its own database and its own configuration.
As a company that has strong relationship with nature and provides products using nature's blessings, Mercian Corporation is committed to the environment. Its environmental philosophy is "Mercian thanks nature's blessings and capability that sustain life, and seeks to balance environmental preservation with creating an affluent society."
Recipe management software refers to the computer software used to manage product names and their corresponding recipes and set the recipe data in the control system in order to control the operations of a plant in which multiple materials are blended to manufacture a number of different products.
As for a controller used in a distributed control system (DCS) shown in Figure 1, covering as many applications as possible with a single controller will bring cost reduction effects such as easy engineering and a small controller installation area. Therefore, the controller is required to process large amounts of data more quickly.
In industrialized countries, social trends such as the aging of workers and the decrease in working population are becoming obvious. Substantial problems such as a lack of skilled engineers and increases in the labor cost of knowledge workers are significantly impacting industrial automation users. These problems cause greater economic loss to the users.
The power generation facility in a pulp and paper plant is comprised of units, each of which is composed of a boiler, a turbine, a generator, and auxiliary equipment, and these pieces of equipment were traditionally controlled on a unit/equipment basis. This paper presents an application of CENTUM, Yokogawa's distributed control system (DCS) that integrates the independent control systems of such power generation facilities to achieve labor saving through operations via CRT display and keyboard.
In recent years it has become increasingly common for plants to be provided not only with the control layer of a production control system (DCS, etc.), but also with the protection layer of a safety instrumented system (SIS) to reduce the risk of industrial accidents. The safety instrumented system is indispensable for avoiding risks to a plant failure.
The requirements for water supply and sewage services are becoming increasingly strict, such as consolidation of facilities, operational efficiency, lower cost, and information transparency due to stagnant demand. There is also demand for greater use of information technologies (IT), encouraged by the government's e-Japan strategy.
Instrumentation devices and equipment serve for plants as the eyes, ears, nose, tongue, and skin, which are responsible for the five senses, and act as the central nervous system and brain do for human beings. The reliability and availability of such devices and equipment are the most important requirements of customers.
CENTUM VP is a next-generation Integrated Production Control System which provides solutions to improve operation efficiency (Operational Excellence) based on Yokogawa's VigilantPlant concept. In the development of Integrated Production Control Systems, we have expanded the functions of the Human Machine Interface (HMI) maintaining the main essence of CENTUM series, regardless of the changes of platforms.
Yokogawa proposed the VigilantPlant concept as an ideal plant that achieves fully optimized operation where all the necessary information is given to all the operators involved in the plant operation. In VigilantPlant, operators are able to quickly respond to changes in the external environment while the production activities run without any interruption.
FCSs, the control stations in a CENTUM CS system, have already demonstrated that they are highly reliable, effective and maintainable. These advantages are the result of such features as the dual-redundant hardware configuration, the online modification of application data, and so on.
The environment surrounding process control systems has changed dramatically as the performance of personal computers improves and the Windows operating system advances, there has been a move towards the trend of open architecture. As we are already aware, in addition to the traditional high reliability level and the unique operability there has been an increase in demand for the interoperability of human- machine interfaces (HMI), which are responsible for the operation and monitoring of our distributed control system (DCS).
In process control it is not uncommon for systems to be affected by dead times, due to material transfer times. This is evident typically in pipelines. A fluid of density ρ and flow rate w in a section of pipe A the length of d takes the amount of time τ = ρAd/w to cover the whole distance (see Figure 1).
Industrial automation (IA) systems and products, which utilize measurement, control and information technologies, are used across the world as fundamental infrastructure for achieving safe, stable and highly efficient plant operation. In order to keep the systems and products effective throughout the plant lifecycle, customers need to periodically check their effectiveness and take prompt action if any problem is identified.
In Japanese industries which grew rapidly until the early 1990's, solid production techniques for creating high-quality products supported the development of manufacturing industries. However, the economic environment has been changing rapidly and tough global competition has become unavoidable. Particularly, the manufacturing industry must adapt not only to changes in economic environments but also to changes in social conditions such as emphasis on health, safety, and environment (so called HSE).
Upgrading and renewal of plant facilities, including production control systems and safety instrumented systems, are essential for maintaining safe and efficient plant operation. Even though these activities are categorized as R&R, they require investment and customers are often required to evaluate the profitability for obtaining approval.
Conventional safety instrumented system (SIS) is typically installed separated from a distributed control system (DCS) to eliminate interference from the DCS and assure safety. However, users increasingly wish to integrate SIS with DCS while maintaining the safety of safety controllers.
Yokogawa's ProSafe-RS safety instrumented system is used for many applications as a system conforming to the safety integrity level (SIL) 3 defined in the IEC61508 international functional safety standard. To deal with temperature inputs, systems were conventionally configured using signal conditioners.
Report functions in process control are often positioned as part of the logger functions. However, plant operation data in a batch process should be not only logged regularly but also acquired and managed for each batch execution. The report function for logging plant operations in a batch process mainly comprises a function to print out plant operation data collected for each batch execution, and there are various approaches available to implement this function.
Drastic changes in the economy of manufacturing industries, has led to increasing demand for plant operations to reduce personnel, improve efficiency, and increase the operation rate of facilities. On the other hand, for plants to operate safely, improvements in reliability and operational safety cannot be neglected.
The CENTUM CS 3000, a reliable distributed production control system, has been introduced worldwide with the objective of operating plants efficiently 24 hours a day, every day. The CS 3000 handles abnormal conditions in a plant appropriately and minimizes the chance of them developing into faults.
In recent years, expectations for control systems using wireless communications have been increasing in the process control market. This is because these systems do not require power and communication wiring for field instruments, enabling reduced initial and maintenance costs, and easy installation.
In this day and age, just simply buying a personal computer, taking it home and turning it on will enable you to be taken to the world of Internet. In such an era, communication connection capability and prospects is increasing in importance. DCSs are no exception for concern.
To date, Yokogawa has focused on DCS (Distributed Control System) which control the entire power generation plant, including boilers, in the electric power industry. In contrast, turbomachinery control has been handled by turbine manufacturers, but as the electric power market has been active internationally, especially in China and India, in recent years, Yokogawa has been developing turbomachinery control systems to to further develop the electric power industry.
For a transfer system in a plant, such as a transfer between tanks in a brewery, the transfer of pellets in a pneumatic transport system, or the transfer of oil at an offsite location, it is necessary to monitor the open/close status of valves or the on/off status of motors or blowers in reference to the transfer pattern (a combination of the transfer source(s) and destination(s), route, etc.).
The operation and monitoring functions of a plant control system are important means of understanding the condition of the plant and how it operates. Traditionally, user needs for the system focused on such features as increased operability and durability. As a result, these functions were developed for a dedicated machine in the form of dedicated human-machine interface software.
The innovation of wireless technology increases the use of wireless communication in the industry. The introduction of wireless communication to plants, however, requires strict features such as robustness, real-time responsiveness, and low power consumption. This has restricted the use of wireless communication to limited applications such as data logging and device status monitoring that does not require strict real-time responsiveness and data arrival reliability in communication.

Your next automation system will have to do far more than real-time control,as the demands for new capabilities are rapidly growing. Bruce Jensen writes.
By Bruce Jensen, General Manager, Technical Solutions Support Center, VigilantPlant Solutions and Services, Yokogawa Corporation of America, and Joshua Kyaw Zwa, Executive Engineer, System Marketing Department, Marketing Operation, Yokogawa Engineering Asia Pte. Ltd.
...and then you plan an intelligent automation solution.
In an ideal automation project, time is unlimited, and project budgets are generous. The plant implementing such a project has the luxury of automating all of its field actuators, great and small.
Yokogawa's web-based DCS Anywhere has simplified commissioning at the Nanhai petrochemicals complex. With a total investment of 4.2 billion US dollars, the Nanhai petrochemicals complex at Daya Bay in Huizhou, China, has attracted a lot of attention because of its sheer scale.
Industrial Automation Asia, August 2012
For the past 35 years, developments of a distributed control system (DCS) have been evolving to raise productivity and enhance plant operation. As field instruments advance, there is a need to exchange large amount of process data and parameters among various diagnostic devices for stability of plant operation.
As industrial facilities take on more complex tasks and lose in-house expertise, they ought to be able to rely on suppliers to show the way and help them achieve their goals.
The 2008 Frost & Sullivan Asia Pacific Company of the Year Award for Distributed Control System (DCS) market is presented to Yokogawa. Yokogawa is the market leader with a dominant market share in the Asia Pacific market.

An exception level of engineering expertise tailored for the local market is one of the primary reasons why Yokogawa has managed to capture and keep the process automation top spot in the Land of Smiles, says Somkid Teraboonchaikul, managing director, Yokogawa Thailand.
As a world's leading supplier of instruments and control systems for industrial process automation, Yokogawa has committed itself to the development of advanced solutions and products in three focused areas – measurement technologies, industrial automation and control, and information technologies.
Yokogawa has taken a vital step in their plan to make the world's plants 'silent and boring', and therefore, well-managed, with the release of their new integrated production control system CENTUM VP last month.
Process automation in oil refineries is undergoing major changes, driven by customers frustrated by what they consider to be slow and incremental advances from the main automation original equipment manufacturers (OEMs) in the industry. ExxonMobil has become a de facto industry representative and is driving vendors like Yokogawa and others to reevaluate how large-scale automation projects are implemented.
At ARC Process Management Academy (PMA) in Antwerp Yokogawa's contribution to plants in Europe was introduced.
Oil producers looking past today's difficult world markets understand development of new sources will bring a growing list of challenges. An ever-increasing amount of oil and natural gas is being produced by techniques once considered unconventional: tar and extraction, fracking, and deep water offshore drilling. As the costs of these extraction methods have gone down, the range of economically recoverable deposits has increased. When crude oil markets return to more normal levels, these difficult fields, including deep water offshore oil and gas, will become increasingly important.
By Eugene Spiropoulos, Yokogawa Corporation of America
Honeywell and Yokogawa have both been producing Distributed Control System (DCS) platforms for decades, and both are very active in this area. In 1975, Honeywell introduced its TDC2000 platform and Yokogawa brought out CENTUM. These two competing systems emerged from a similar place, oil refining and petrochemical industries, so they started out with similar basic concepts and use cases in mind.
