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 

Activities with ISA-95 Enterprise-Control System Integration Standard

The ISA-95 standard provides a framework for exchanging manufacturing data between enterprise and manufacturing systems as well as between different Manufacturing Operations Management (MOM) systems. The standard has been widely adopted by manufacturing companies in the continuous, batch and discrete industries and by system suppliers at the MOM and enterprise levels.

Yokogawa is an active participant in the committee and supports the standard in our products and solutions.

The U.S. based ISA-95 standard has been internationally accepted as the IEC/ISO 62264 standard. The standard consists of five parts:

Parts 1 and 2 define a framework for exchanging data between Enterprise (Level 4) and Manufacturing Operations Management (Level 3) systems. Parts 1 and 2 were originally published in 2000 and 2001 respectively. In 2010 updated versions of both Parts were released. The updates incorporate feedback from users of the standard and knowledge gained writing Parts 3, 4 and 5.

Part 3 defines Manufacturing Operations Management activities and is widely used by manufacturing companies to describe their MOM requirements and functions.

Part 4 defines models for data exchange between functions within Level 3 (MOM).

Part 5 defines how data from Parts 1 and 2 can be exchanges as software transactions. This aids in automating the exchange of data.

IEC Joint Working Group 5 (JWG 5)
The international version of ISA-95 is IEC/ISO 62264. This international standard is being developed jointly by IEC and ISO in Joint Working Group 5 (JWG5). IEC participation in Joint Working Group 5 is under Subcommittee 65 (SC 65) of Technical Committee 65 (TC 65). The ISO participation is done by Joint Working Group 5 under Subcommittee 5 of Technical Committee 184.

The IEC/ISO work follows the U.S. ISA-95 publications. When the ISA-95 version is completed it is submitted to JWG 5 for consideration as international standard.

Participation on JWG 5  is coordinated through each member country’s national standard organization.

B2MML (Business To Manufacturing Markup Language
B2MML, the Business To Manufacturing Markup Language, is an XML implementation of ISA-95. B2MML consists of a set of XML schemas written using the World Wide Web Consortium's XML Schema language (XSD) that implement the data models in the ISA-95 standard.

Yokogawa was instrumental in the creation of B2MML and currently works with MESA International to ensure B2MML stays current with ISA-95 updates and remains freely available for the industry to use. For more information on B2MML or to download a copy go to B2MML (Business To Manufacturing Markup Language). 

Activities with ISA-99 (IEC62443) Industrial Automation and Control Systems Security

ISA-99 is multi-part group of standards and associated technical reports which address the issue of cyber security in industrial automation and control systems. The standards are grouped into four broad areas:

• Concepts and terminology
• Asset Owner specific, including creation and maintenance of a security program
• Secure integration of control systems, including the zone and conduit model
• Product development and technical requirements of control systems.

The standards and associated technical reports are in the process of being converted to the IEC format and it is expected that most will be available by the end of 2013. The current status of the standards can be found on the ISA site .

Yokogawa actively supports both ISA-99 and the associated IEC standards and contribute to the creation and maintenance of these standards. The development of new products within Yokogawa follows these standards to ensure we produce secure, reliable systems. 

Activities with ISA-101 Human Machine Interfaces (HMI)

The ISA101 standards committee was formed in 2006 to establish standards, recommended practices, and/or technical reports pertaining to designing, implementing, using, and/or managing human-machine interfaces in manufacturing applications. The committee is co-chaired by Dr. Maurice Wilkins of Yokogawa Corporation of America and Greg Lehmann of URS Corporation.

The areas covered within ISA101's work includes every facet of HMI design and operation, such as: menu hierarchies, screen navigation conventions, graphics and color conventions, dynamic elements, alarming conventions, security methods and electronic signature attributes, interfaces with background programming and historical databases, popup conventions, help screens and methods used to work with alarms, program object interfaces, and configuration interfaces to databases, servers, and networks.

The standard takes a lifecycle approach categorized into four stages: system standards, design, implementation, and operation.

Each clause is being developed under the leadership of one or two industry experts, with the help of a number of committee members. The clauses are as follows:

• Clause 0: General
• Clause 1: Scope
• Clause 2: Normative References
• Clause 3: Definition of Terms and Acronyms
• Clause 4: HMI System Management
• Clause 5: Human Factors/Ergonomics
• Clause 6: Display Styles and Hierarchy
• Clause 7: User Interaction
• Clause 8: Performance
• Clause 9: Documentation and Training

Draft 3 was sent out for a review by the full committee at the end of April 2012, and Draft 4 at the end of June 2013. After discussions at ISA Automation Week in November 2013, a small working group was set up to get the standard into a format and content to be put forward for ballot in 2014.

Technical reports such as HMI philosophy, HMI style guide, HMI design guide, HMI usability and performance, and HMI purchase specifications have been identified for future development as soon as the standard has been accepted. A new working group is soon to be set up for HMI for mobile platforms.

As of December 2013, the committee member numbers around 230.

Activities with ISA-103 (IEC62453) Field Device Tool Interface

ISA 103 defines the interfaces for both the vertical and the horizontal data flow, called Function Control and Data Access, in the framework of a Client-Server architecture so it will allow application software and configuration tools to interact with field devices in a unified way, while hiding the manufacturer-specific interaction with devices or sub-systems in a software module. ISA 103 supports any field bus, device or sub-system specific software tool that can be integrated as part of a universal life-cycle management tool of a plant automation system.

ISA 103 committee is currently working on the following items:

• Review and revise scope of ISA 103 to support FDI
