Updated Fire and Gas Technical Report
The ISA84 standards committee, Instrumented Systems to Achieve Functional Safety in the Process Industries, has completed a revision of ISA-TR84.00.07, Guidance on the Evaluation of Fire, Combustible Gas, and Toxic Gas System Effectiveness. The technical report is intended to help address detection and mitigation of fire, combustible gas, and toxic gas hazards in process areas. Fire detection and mitigation within non-process areas are outside the scope of the document.
Fire and gas systems are used in the process industries to detect loss of containment of hazardous materials from a process and initiate a response to mitigate the release impact. Loss of containment can be a small leak or a catastrophic release. It can be detected by measuring the presence of the released materials or inferred from the effects of the release.
New HMI Technical Report Focuses on Usability and Performance
ISA’s first human-machine interface (HMI) standard, ANSI/ISA-101.01, Human Machine Interfaces for Process Automation Systems, covered the philosophy, design, implementation, operation, and maintenance of HMIs for process automation systems, including multiple work processes throughout the HMI life cycle. It defined the terminology and models to develop an HMI and the work processes recommended to effectively maintain the HMI throughout the HMI lifecycle, including all general concepts until its decommissioning, applying a practical and management approach.
The ISA101 standards committee has now published the first in a series of technical reports to provide further guidance in key areas of HMI. ISA-TR101.02, HMI Usability and Performance, addresses the specification, design, implementation details, and management of an HMI focused on usability and performance. It explains how the ISA-101.01 standard applies in determining the optimal solution in order to achieve the process goals using examples that have been shown to be effective.
HMI enhancements for improved usability and performance are often associated with additional specifications, custom design, implementation, and management considerations, in addition to vendor-provided functionality and features. The new technical report includes examples of these considerations within the HMI lifecycle, including the continuous work processes of audit, validation, and management of change.
The ISA101 committee is currently working on additional technical reports in three areas: HMI philosophy and style guide; mobile devices such as tablets and smart phones; and on-machine applications, focused on developing HMI graphics that effectively convey contextual information for operating and maintaining a machine.
For information about participating in the ISA101 committee, contact Torry Bailey, ISA Standards, email@example.com.
New Control Valve Terminology Standard
ISA75, Control Valve Standards, has completed a revision of ISA-75.05.01, Control Valve Terminology. The standard provides a glossary of definitions commonly used in control valve applications across industry. The standard includes a number of new or significantly revised terms, including backlash, cage guiding, intelligent/smart positioner, quick change trim, globe valve body, hysteresis, port guiding, and post guiding.
Updated Fossil Fuel Power Plant Standard
ISA77, Fossil Power Plant Standards, has completed a revision of ANSI/ISA-77.42.01, Fossil Fuel Power Plant Feedwater Control System. The standard is intended to assist in the development of design specifications covering the measurement and control feedwater systems in boilers with steaming capacities of 200,000 lb/h (25 kg/s) or greater. The safe physical containment of the feedwater must be in accordance with applicable piping codes and standards and is beyond the scope of this standard.
Feedwater control systems are used in the process industries to monitor changes in steam flow, water flow and drum level. Power plants that use fossil fuels or produce nuclear reactions for the generation of electricity require a significant amount of water daily for steam production and cooling purposes. Control of these three variables is critical to maintain safe and reliable feedwater systems and promote plant efficiency.
ISA77 Fossil Fuel Power Plant Simulators Update Seeks Participants
In his review of ANSI/ISA-77.20.01-2012, Fossil Fuel Power Plant Simulators - Functional Requirements, Bill Talbot, ISA77.20 Working Group Chair, determined that the material requires a revision and update. As the current membership of the working group is low, Bill is seeking new participants to evaluate, rewrite, and supplement the standard where needed.
The 2012 standard addresses the simulation of fossil fuel power plants typically consisting of:
The document establishes the functional requirements for several types of plant-specific, fossil fuel power plant control room simulators. Although operating and training practices and procedures differ among the various operators of fossil fuel plant control room simulators, the goals of personnel safety, maximum equipment availability and lifetime, and efficiency of operations are common to all. Therefore, this standard provides flexibility in both design and use.Work on the revision will be handled through periodic Skype meetings.

ISA99 to Develop Report on Industrial IoT Cybersecurity
ISA99, Industrial Automation and Control Systems (IACS) Security, has begun work on an ISA Technical Report to be titled Applying ISA-62443 to the industrial Internet of Things (IIoT). Coverage will include general categories of IIoT devices within IACS, cybersecurity challenges, and rates of adoption in industry. The report will then serve as a guide in determining if any new and related ISA99 work products are required.
The technical report will be the first work product of Working Group 9, IIoT and Security, which was established by ISA99 to analyze the specific characteristics of the IIoT in terms of threats, attack surface, and vulnerabilities, and to examine whether the approach developed by ISA99 for securing a conventional IACS is appropriate and sufficient for IIoT. This assessment is vital as the IIoT is a specific case of IACS with a very wide range of objects, an extended surface area and a high scalability, resulting in a very large attack surface and new vulnerabilities. The working group will first examine the specific risks and new forms of attack to which the IIoT may be subject.
This project is one of numerous current development activities within ISA99 to support and advance the widely used ISA/IEC 62443 series of standards on IACS security. The standards are developed primarily by ISA99 as American National Standards, with simultaneous review and adoption by the Geneva-based International Electrotechnical Commission through IEC partner committee TC65, Industrial-Process Measurement, Control and Automation. With over 900 members, ISA99 draws on the input of cybersecurity experts across the globe in developing the standards, which are applicable to all industry sectors and critical infrastructure in providing a flexible and comprehensive framework to address and mitigate current and future security vulnerabilities in IACS.
ISA99 Working Group 9 is chaired by Suzanne Lightman of the US National Institute of Standards and Technology. For information on ISA99, contact Eliana Brazda, email@example.com . For information on viewing or obtaining the ISA-62443 standards and technical reports, visit www.isa.org/findstandards.
The time-honored PID (proportional–integral–derivative) algorithm is used in a vast majority of applications for basic control and many for advanced control. However, there appears to be a widespread lack of understanding of the different forms, structure, features and how performance objectives determine appropriate choices. Consequently, most of the capability of the PID is underutilized, reducing process safety, efficiency and capacity, points out ISA Fellow, author and mentor Greg McMillan, a widely recognized expert on process control who received the ISA Lifetime Achievement Award in 2010.
This concern prompted McMillan to propose a new ISA standards project on controller algorithms and performance, which has led to the recent formation of ISA5.9, Controller Algorithms and Performance. The new working group will function under the ISA5 committee, Documentation of Measurement and Control Instruments and Systems.ISA5.9 will seek to clarify the algorithms used in industrial control systems to aid in their selection and application to improve manufacturing processes. The working group will develop technical reports, recommended practices, and standards documenting the algorithms used in
industrial control systems and the measures of performance for those algorithms. The documents may include guidance on algorithm selection.
ISA5, the oversight committee for ISA5.9, is also responsible for the widely used standard ISA-5.1, Instrumentation Symbols and Identification. The committee is chaired by former ISA Standards & Practices Department Vice President Tom McAvinew, co-author of the ISA book Control System Documentation: Applying Symbols and Identification.
The ISA5.9 cochairs are Yamei Chen of Eli Lilly and Company, Indianapolis; and Michel Ruel of BBA, Québec. Those who are interested in participating in the new ISA5.9 are asked to contact Charley Robinson, ISA Standards, firstname.lastname@example.org .
