概述:

Facing serious environmental problems for the whole earth, clean energy using solar, wind, geothermal, tidal, etc... to reduce CO2 emissions is an inevitable matter. Renewable energy providers need economical/reliable/efficient solutions. Yokogawa provides a reliable data acquisition system with high accuracy for measurement and control instruments.

概述:

The automation suppliers that will be successful in the long term will be those that effectively address application or industry specific problems for end users with a value proposition that cannot be ignored. These problems exist throughout the process industries today, and they won't be solved by simply offering a product, but through a combination of hardware, software, services, application expertise, and knowledge.

概述:

In ARC's view, customers need a compelling business value proposition to justify investment in any kind of automation. Vigilance and VigilantPlant were created with this in mind. Yokogawa's vision with VigilantPlant is to create an environment where plant personnel and operators are well informed, alert, and ready to take action. 

概述:

This white paper provides an overview of how Yokogawa believes its customers can best prepare for and position themselves to benefit from IIoT-enabled technology and solutions and digitalization in general to emerge as the successful connected industrial enterprises of the future.

概述:

Yokogawa’s industrial automation (IA) product and service offerings, industry domain knowledge, and VigilantPlant approach – which emphasizes safe, secure, and uninterrupted operations -- provide a solid foundation for an Industrial Internet of Things that specifically addresses the requirements of process automation, particularly for the OT side of the equation. To be able to provide an equally solid foundation for the IT side, Yokogawa is partnering with Cisco Systems and other industry leaders.

概述:

Yokogawa has come a long way in making its message clear to the world of process automation. Last year, the company embarked on a full-scale global marketing campaign to make customers aware of the company's 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.

概述:

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.

概述:

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.

概述:

Recently, manufacturing industries are trying to slash the total cost of ownership (TCO). Batch processes are not exceptions. Until recently, in comparison to continuous processes, batch processes have generally not yet undergone systematization and standardization.

概述:

As industrial plant systems have increased in scale and their automatic control algorithms advanced, today's operators are required to have more advanced skills and knowledge of theplant systems and to learn the actions to be taken in response to any possible situations including emergencies.

概述:

The trend of open system architecture is becoming an important issue with distributed control systems (hereinafter abbreviated as DCSs). To meet this demand, the operation and monitoring functions, and the system generation functions of the CENTUM CS 3000 system are designed to support Windows NT and OLE for Process Control (OPC).

概述:

As more fieldbus devices are made practicable, demand is increasing for a distributed control system (DCS) which integrates fieldbus devices in its engineering, operation, and monitoring environments. Conventionally, control has been implemented by the dual-redundant CPUs and control bus within a DCS; however, sufficient reliability must be ensured even when it is distributed over field networks.

概述:

The recent increase of devices enabled for a field network such as the FOUNDATION™ Fieldbus is phenomenal. This has been amplifying a requirement for distributed control systems (DCSs) to be capable of constituting a more pliant and efficient production control system by means of flexible connections to field networks in addition to traditional 4 to 20 mA signals.

概述:

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).

概述:

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.

概述:

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.

概述:

The manuals of control systems such as a DCS provide a vast amount of information depending on their multi-functionality and functional integration. A conventional large-scale control system our company offers comes with more than 10,000 pages of paper documents.

概述:

Yokogawa Electric has been using Pair & Spare method as a reliability-enhancing technology for its line of distributed control systems (DCS) since the release of the CENTUM CS in 1993. As a result, the system has achieved an availability factor of seven 9's (99.99999%) for the record of operation to date.

概述:

Improved plant operation efficiency and reduced maintenance costs based on appropriate predictive maintenance are the common objectives that need to be achieved in every manufacturing domain. Exaquantum is positioned above the Process Control System (PCS) layer and gathers and stores huge volumes of process and laboratory data over long terms.

横河技报
概述:

Environmental friendliness (E) must be assessed in today's product design in addition to the conventional design considerations of quality (Q), cost (C), and lead time (D). Hence, the product design system must be urgently restructured in order to minimize the environmental impact of a product throughout its life-cycle from purchase of the materials and parts, through manufacturing and distribution, to use and disposal.

概述:

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."

概述:

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.

概述:

Global market pressures are causing businesses world wide to strive to lower manufacturing costs and to become more agile companies in order to quickly respond to changes in market demands and to fend off competitive threats. Yokogawa's customers in all industries and markets are responding to this pressure by working to more closely integrate their plant manufacturing systems with their enterprise wide business systems in a seamless manner.
