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,
tbailey@isa.org.
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:
- Boiler, turbine, and balance of plant with
steaming capacities of 200,000 lbs/hr (25 kg/s) or greater
- Combustion turbine or combined cycle
combustion turbine capacity of greater than 100MWs
- Associated or interactive processes
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.

Standards Administrator, ebrazda@isa.org
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,
ebrazda@isa.org . For information on viewing or obtaining
the ISA-62443 standards and technical reports, visit

New ISA5 Project
on Controller Algorithms and
Performance
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,
crobinson@isa.org .
