• To bring the customer a real-time monitoring and management capability, Yokogawa installed STARDOM (FCJ), flow meters, and transmitters at key points throughout the distribution network.
• The STARDOM FCJ controllers achieved an accurate water loss management system while keeping the running costs to a minimum.

• Reduced cabling costs by using a commodity GPRS network infrastructure
• Additional reduction in system cost by making full use of existing components
• Reduction in cost of software by using all web-based technology
• Long-term service contract — no need to worry about a suspension of maintenance services

• STARDOM and FAST/TOOLS integrated SCADA solution for Indian Oil Corporation's multiproduct oil pipeline.
• STARDOM facilitates the total visualization of data needed for safe and reliable pipeline operations.

• Reduced risk through distributed installation
• In-house engineering to ensure ability to perform maintenance and modification
• Time-efficient replacement using the five IEC61131-3 languages
• Ease of connecting with display panels and MES

• Yokogawa provides STARDOM and FAST/TOOLS for biomass pilot plant.
• FAST/TOOLS is an "all in one" SCADA solution that functionsa a data historian.

• Scalable, flexible configuration with functions distributed to multiple controllers on a facility basis
• Redundant architecture optimally designed for requirements of entire plant
• General-purpose communications network used for control bus
• Integrated operation environment through web-based human-machine interface (HMI)

The Nanjing Municipal Environment Monitoring Center (NMEMC) was looking for a better system that could be adopted for use in online pollution monitoring. For the following reasons, Yokogawa STARDOM autonomous controllers with embedded Web servers were selected for this air emissions and waste water surveillance data collection and transmission system:

• The aging DCS system was replaced with an integrated control system for all processes at the Siheung water treatment plant.
• Powerful Modbus communication function of STARDOM enables integration with the existing HMI via the OPC gateway.

Many different types of gases are consumed in industries as varied as chemicals, food & beverages, and medical. These gases are normally delivered in liquid form by trucks and dispensed at the customer site. Although the flow volume of cryogenic liquefied gas is used for billing purposes, it is not easy to accurately measure this because the gas is always at saturation temperatures.

An automatic custody transfer system for unmanned LNG gas stations that embeds PC oriented functions such as e-mail, FTP, and the Java runtime environment in a robust hybrid controller.

STARDOM field control node (FCN) autonomous controllers allow both Modbus master and slave functions to run simultaneously.

Yokogawa ensures a reliable heat and CO₂ transfer system by using the standard GPRS protocol. The exclusive use of webbased technology enables the market gardeners to go online to order heat and CO₂ and view information.

Yokogawa provides controller embedded flow calculation library based on AGA (American Gas Association) reports.

The discharge of improperly treated industrial chemicals and fuel gas can have a major impact on the environment, posing a serious threat to public health. Concurrent with the global growth of manufacturing operations to keep pace with market trends, many countries are taking measures to deal with environmental problems.

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.

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.

Due to the rising energy demand in emerging countries in recent years, the amount of oil and gas production has been increasing, thus investment in the development of new oil and gas fields and replacement of old facilities has been booming.

Laser interferometers and linear scales are used for measurement of the moved distance or positioning on the stage of precision machining equipment such as manufacturing equipment for semiconductors. The laser interferometer, in particular, features high accuracy, non-contact measurement and easy installation.

For the liquefied natural gas (LNG) industry, which has witnessed healthy growth and large project investments over the last few years, Asia is right at the center of the action. Whenever any sector booms in the economy, as is the case with the liquefied natural gas (LNG) production-transport-gasification distribution network the world over, there is a concomitant growth in the demand for automation solutions.

LNG Industry, Summer 2012

Martin te Lintelo, Yokogawa, The Netherlands, discusses the need for better automation, measurement and control instruments to cope with the rising popularity of LNG.

On April 18th 2018, YOKOGAWA has released the new unit extension module: “E2 bus interface module” for the STARDOM autonomous controller “FCN-500”. Excellent Scalability and Excellent Reliability, FCN-500 has evolved with “Excellence × 2”.

Providing an introduction to the features of STARDOM autonomous controller ‘FCN’. “Faster, Stronger, Smarter”, the FCN-500 STARDOM controller strengthens your core competencies with field proven reliability.

Yokogawa presents a demonstration of how the combination of Stardom FCN-RTU and FAST/TOOLS SCADA can be combined to provide a powerful control and data collection system where in the event of a network disconnection or computer outage - Stardom internally buffers data that would otherwise be lost and on reconnection or restoration of the SCADA Server FAST/TOOLS is able to back-fill missing data in its trend.

New CPU module for the STARDOM autonomous controller 'FCN' is unveiled. “Faster, Stronger, Smarter” controller will strengthen your competencies.
