A Distributed Control System (DCS) is an automated control solution widely used in industrial plant operations. In the instrumentation industry, it’s commonly known as a DCS. Unlike centralized systems, a DCS decentralizes control by assigning controllers to individual pieces of equipment. This approach enhances system reliability and allows for efficient, long-term operation of large-scale plants, while also reducing labor requirements and improving operational efficiency.
The CENTUM VP Series is the latest evolution of the renowned CENTUM family—the world’s first DCS to integrate cutting-edge digital control technology with decades of industry experience and expertise. Since its debut in 1975, CENTUM systems have been installed in over 30,000 facilities across more than 100 countries, setting the global standard for process automation. CENTUM VP provides the industry’s highest field-proven system availability, enterprise-wide interoperability, extensive advanced solutions portfolio, and third-party-certified defense-in-depth cybersecurity to increase productivity and improve plant operations.
Delivering simplified upgrades and backward compatibility by design for 50 years, Yokogawa exceeds the needs of operators throughout the product lifecycle.
Yokogawa is joining hands with leading high technology companies worldwide to supply highly reliable and sophisticated distributed control systems.

Yokogawa activities in the ISA Standards Committees
Yokogawa is the member of the following ISA standards committees taking active roles for standardization.
Activities with ISA-18.2 Management of alarm systems in the process industries
This standard provides requirements and recommendations for the activities of the alarm management lifecycle. Lifecycle stages include philosophy, identification, rationalization, detail design, implementation, operation, maintenance, monitoring & assessment, management of change, and audit.
There are currently six Technical Reports (TR) for ISA18.2 that have been published.
Yokogawa supported the Working Groups (WG) that authored technical reports and is actively involved in WG7- Alarm Management for Plants Incorporating Packaged Systems.
Yokogawa provides consulting for alarm philosophy preparation, alarm identification and rationalization, defining alarm KPIs and reporting requirements all in the support of the ISA18.2 standard
Yokogawa products support the standard, such as Consolidated Alarm Management Software (CAMS) as part of our CENTUM VP platform, Alarm Reporting and Analysis (ARA) , Alarm Master Database (AMD), and Advanced Alarm Administrator (AAA Suite).
Promoting batch process control
Yokogawa continues to be dedicated to the standardization of batch process control, promoting a unified method and architecture for designing batch process control schemes. A standardized approach to batch process control benefits batch processing companies by lowering their costs to build and operate batch processes and reducing the lead-time required to introduce new products.
Yokogawa continues to be active in standards and educational organizations related to the development of batch control standards. We have developed products that comply with the ISA-88 (IEC 61512) standards and utilize the standard approach in our batch control implementation projects. Yokogawa supports the continuing standardization work in the batch process industries.
Activities with ISA88 Batch Control Standards Committee
The ISA88 Batch Control Standards Committee is the leading organization in the world regarding batch process control. The ISA88 committee is responsible for developing and maintaining the ISA88 Batch Control Standard which is recognized as the definitive document regarding batch process control. Internationally the ISA-88 standard is also known as IEC 61512 which is maintained by the IEC’s Sub-Committee 65A under Technical Committee 65. Yokogawa has been a strong supporter of the ISA88 committee since it was founded in 1988. Our members have contributed to the creation of all parts of the ISA-88 Batch Control System standards. The four parts of the standard are:
ISA-88 Batch Control – Part 1: Models and Terminology
ISA-88 Batch Control – Part 2: Data Structures and Guidelines for Languages
ISA-88 Batch Control – Part 3: General and Site Recipe Models and Representation
ISA-88 Batch Control – Part 4: Batch Production Record
Part 1 of the standard was updated in 2010 based upon feedback from the batch control community that had been using ISA-88 since the mid-1990’s. For information on how to obtain the updated ISA88 standard or learn more about the ISA88 committee go to ISA.
BatchML (Batch Markup Language)
BatchML, the Batch Markup Language, is an XML implementation of ISA88 family of stanards. BatchML consists of a set of XML schemas written using the World Wide Web Consortium's XML Schema language (XSD) that implement the models and terminology in the ISA-88 standards.
Yokogawa was instrumental in the creation of BatchML and currently works with MESA International to ensure BatchML stays current with ISA-88 updates and remains freely available for the industry to use. For more information on B2MML or to download a copy, go to: Batch Markup Language
It depends on the mode. In 10 ch mode, measurement can occur on CH1-CH10; in 2 ch mode, CH1-CH2. In 10 ch mode, A/D integral time is fixed at 1.67, and measured values (especially with temperature measurements from thermocouples) may fluctuate because power-line period noise is not eliminated. In 2 ch mode, A/D integral time is fixed at 16.67, and power-line period noise can be eliminated. For operation mode settings, see the user's manual (IM 04L51B01-01EN) ◊1.7.3 "Setting the Operation Mode for a Module."
