Ever since Exaopc was put on the market in 1999, it has been used by many OPC client programs including Plant Information Management System (PIMS), advanced operation support packages and advanced control packages as a common interface for looking up process data.

概述:

As international price competition becomes increasingly fierce, high value-added, high-efficiency production is essential for the survival of production plants in the oil refining, chemical and other industries. On the other hand, if plant equipment, which is the foundation of these production industries fails, business opportunities will be lost due to loss of yield, environmental destruction, and weakened financial strength due to social compensation.

概述:

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.

概述:

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.

概述:

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.

概述:

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.

概述:

The rapid evolution of information technology (IT) has made possible the transmission of a wide range of information in a short period of time, resulting in the transformation of society in aspects such as logistics and business styles. During this transformation, quick assessment of the circumstances and prompt actions were also required in the production lines, making real-time collection of field information indispensable.

概述:

Vortex flow meters have been appreciated by users as volume flow meters, which can, in principle, be applied to any flow measurement of liquid, gas, or steam. Volume flow measurement is enough for substances with small variations in density such as liquid. 

概述:

The environment surrounding the process plant industry has changed dramatically because of the recent economic changes, deregulation, and increasingly fierce competition among global companies. Users are strongly requesting instrumentation equipment vendors to reduce total cost throughout the life cycle and help improve the efficiency of plant operation.

概述:

Combustion furnaces such as heating furnaces and boilers in plants include various sizes and types, and serve as energy sources, that is, they are cores in all production activities. Because a large amount of fuel such as gas or fuel oil is consumed in plants, their combustion efficiency directly affects the performance and running cost of the plants. 

概述:

A laser gas analyzer employing the tunable diode laser absorption spectroscopy (TDLAS) method has a feature capable of measuring the concentration of the sample gas with high selectivity for gas components and without contact only by irradiating the gas sample with light from a tunable diode laser. Thus fast and accurate in-situ measurements can be performed in process lines under various measurement conditions.

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:

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

 
概述:

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.

概述:

The development of communications technologies has formed a system structure known as the communication network. This network has not only established itself in the industrial world but also in the general household. The recent spread of technologies such as the Internet has been quite spectacular.

概述:

A communication system for connecting stations in the system plays an important role in a distributed control system (DCS). The communication system determines the superiority or inferiority of the entire control system. In DCS communication as represented by CENTUM, a token-passing system and dual bus have been developed.

概述:

It goes without saying that the reduction of the total cost of ownership (TCO) for various facilities and equipment is an important objective for most enterprises, and distributed control systems (DCSs) are no exception.

概述:

As controlled objects have become more complex, plant operation schemes more concentrated, and plant operators fewer in number, the degree of engineering for a distributed control system (DCS) has both multiplied and diversified. Despite this, systems are required to be configured in a shorter time while engineering results are required to be of higher quality.

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:

The number of work steps involved in engineering a batch process tends to become extremely large compared to continuously controlled processes, if the work is automated using a DCS. This is due to the nature of batch processes and the plants that handle these processes.

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:

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:

In order to run 24 hours a day in large-scale plants, such as an oil-refinery or others, a distributed control station (DCS) requires high reliability. In the CENTUM DCS from Yokogawa Electric Corporation, high reliability of each device and a network (bus) connecting devices have been realized by using techniques such as a dual CPU, dual I/O, and a dual communication bus since sales began in 1975.

概述:

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.

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:

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.

概述:

Since their conception in 1975, distributed control systems (hereinafter, referred to as DCSs) have been changed drastically in accordance with the rapid advancements in computer technology. In terms of hardware technology, the development of microprocessors, memory devices, and communication devices has been significant in regard to both quality and quantity.

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:

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.).

概述:

Remarkable progress in information technology has led to open architecture systems and networking in the manufacturing industry. In such industry, remote monitoring systems based on public communication lines or the Internet, and or collaboration of control, information, and corporate systems based on standardized interfaces such as OLE for Process Control (OPC) are now widely used via networks.

概述:

There is growing recognition of the importance of preventing serious accidents in the process control field in view of the potential scale of impact on society. The IEC 61508 and IEC 61511 international standards call for the reduction of risk using safety instrumented systems (SIS) as well as the configuration of multiple protective layers in a process control system in order to prevent major accidents.

概述:

There are already safety systems on the market that have achieved safety integrity level SIL3 of the functional safety standard, IEC61508. However, most of them have achieved SIL3 by conversion of modules into dual-redundant or triplex form.

概述:

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.

概述:

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.

概述:

Process automation involves both operation and maintenance. Plant operation and monitoring are mainly conducted by a control system such as CENTUM, while equipment maintenance is handled by Plant Asset Management (PAM) such as Plant Resource Manager (PRM).

概述:

Asset Excellence (AE) provides a set of solutions for maintaining a plant in good condition at reasonable cost to ensure that it works as a production infrastructure. To reduce maintenance costs without causing a risk to production, it is necessary to change from breakdown maintenance to predictive or preventive maintenance.

概述:

The Coriolis flow meter has many features such as direct measurement of mass flow and measurement of fluid density, which other flow meters do not support. Therefore, since being introduced for practical use in the late 1970s, its market has rapidly expanded in many industries such as oil, chemicals, and foods.

概述:

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.

概述:

One solution packaged for production control systems today is a system comprising a PLC and SCADA (Supervisory Control and Data Acquisition) software that runs on a PC. An advantage of these systems is that they can be configured at considerably lower cost than systems that use dedicated devices as they use commercially available PCs.

概述:

The engineering phase holds the largest ratios in control system configuration in terms of both time and money, so improving engineering efficiency is one of the biggest issues when it comes to system integration. In the STARDOM, Application Portfolios (APPF) are devised to dramatically slash engineering costs and increase software reliability.

概述:

We have developed the FCN (field control node) and FCJ (field control junction) autonomous controllers as the core of STARDOM, a solution that actualizes a network-based control system (NCS) Yokogawa proposes for increased production efficiency.

概述:

Field instruments are expected to be equipped with diagnostic functions to predict abnormal process conditions, and are also expected to expand these functions. The ability to extract diagnostic information for prediction and prevention from various physical process quantities measured by devices and make it available allows the user to reduce non-essential and non-urgent maintenance and thus cut maintenance costs.

概述:

Safe plant operation has long been pursued in all industries. Specifically, in the process automation industry which involves many hazardous elements, safety measures including explosion-protected systems have been adopted based on numerous tragic experiences.

概述:

When evaluating mass flow rates using a primary device such as an orifice or nozzle in a differential pressure flow meter in order to make fluid density compensations, the upstream pressure (static pressure) and fluid temperature are measured in addition to the output of a regular differential pressure transmitter.

概述:

Since the release of the DPharp EJ series in 1991 and the DPharp EJA series in 1994, nearly 1.2 million of these transmitters have been operating all over the world. Recently, we have also developed the EJX series of even more compact, lightweight and advanced transmitters with multi- sensing capabilities built using silicon resonant sensor technology.

概述:

In recent years, more field wireless devices have been used in hazardous areas. Meanwhile, in plants that are usually recognized as hazardous areas, there are numerous metallic tanks and pipes that easily shield or reflect radio waves, as discussed later, thus resulting in a poor environment for wireless communication.

概述:

In 1988, Yokogawa launched the ADMAG series of magnetic flow meters with increased resistance to fluid noise and zero stability, employing dual frequency excitation which was developed based on its long-cultivated technology for flow measurement. Since then, the ADMAG family has augmented its application range with such models as explosion-proof and integral types, and a capacitance type.

概述:

Yokogawa has formed an alliance with Shell Global Solutions International B.V. (SGSI) for advanced process control and has been jointly developing related products since then. As part of this collaborative work, we commercialized the Exasmoc multivariable model predictive control package and the Exarqe robust quality estimator package in 2000, which are used to control DCS and PLC systems based on SGSI's multivariable predictive control and quality estimation algorithms—namely, SMOC (Shell Multivariable Optimizing Controller) and RQE (Robust Quality Estimator).

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.

概述:

FieldMate application software runs mainly on a notebook PC and is a key component epitomizing Yokogawa's asset excellence (AE) concept together with Plant Resource Manager (PRM). FieldMate is available in basic and advanced versions. The basic version enables parameter setting and adjustment as well as status check of a field device by directly connecting a FieldMate-installed PC to a Highway Addressable Remote Transducer (HART) device or FOUNDATION™ fieldbus H1 device.

概述:

FieldMate is field device adjustment and configuration software applying Electric Device Description Language (EDDL) and Field Device Tool/Device Type Manager (FDT/ DTM) technologies. The FDT/DTM is being standardized and disseminated by the FDT Group, a nonprofit organization. Yokogawa is also aggressively participating in those activities.

概述:

The FieldMate versatile device management wizard is PC software mainly used for configuring and adjusting field devices. Under the concept of "one tool for all," Yokogawa has been enhancing this software to support a wide range of field devices and field communication protocols.

横河技报
概述:

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.

概述:

Progress in digital signal processing and network technologies has enabled advanced functions which cannot be achieved by traditional field devices with 4-20 mA signal, to be implemented on field devices. Standardization of international fieldbus specifications, notably the FOUNDATION™ Fieldbus, has enabled users to build optimum field networks comprised of freely chosen field devices from various device vendors.

概述:
