A distributed control system (DCS) is a platform for automated control and operation of a plant or industrial process. A DCS combines the following into a single automated system: human machine interface (HMI), logic solvers, historian, common database, alarm management, and a common engineering suite. Over 10,000 plants entrust Yokogawa's DCS to deliver their production goals.
A Yokogawa DCS delivers critical operational infrastructure and enhanced business performance. Key benefits include:
CENTUM VP has a simple & common architecture consisting of human machine interfaces, field control stations, and a control network.
CENTUM users enjoy the industry's lowest total cost of ownership over the plant lifecycle with a progressively compatible upgrade path and rock-solid reliability.
There is no one "right way" for migration -- every plant is unique in its operational priorities, budget constraints, legacy systems, and so on. Standing still with aging assets may not be the best option, but the way forward must be planned carefully and flexibly.
Agile Project Execution provides new engineering possibilities and changes the way projects can be planned and executed, reducing risk and adding flexibility to the schedule.

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.
When distributed control systems (DCS) first appeared on the industrial automation scene in the mid-1970s, the focus was on control and operator interface. While control and human machine interface (HMI) are still important, today's DCSs have evolved to place increased emphasis on integrating plant-wide asset and operational information to enable operational excellence.
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.

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.
Control Engineering Asia, May 2012
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.
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.
