ISA-100 wireless standard receives resounding approval in IEC technical voting
ISA-100.11a-2011, Wireless Systems for Industrial Automation: Process Control and Related Applications, has received approval from all 21 participating national committees to the International Electrotechnical Commission (IEC) that voted on the IEC version in a recently completed committee draft for vote (CDV) stage.
The CDV stage is the final stage in the IEC process in which technical comments may be considered. The standard, expected to be issued in early 2014 for a final IEC approval stage in which no technical comments may be submitted, will carry the designation IEC 62734 upon publication.
This follows previous approval of ISA-100.11a as an ISA and American National Standard. The latter confirmed that ISA's open consensus standards development procedures as accredited by the American National Standards Institute (ANSI) were followed properly in developing ISA-100.11a. ANSI requires participation not only of suppliers but of all key interest categories.
ISA's ANSI-accredited procedures allow experts from end-user companies to directly participate and vote, ensuring consideration of the views and requirements of those who will actually be deploying wireless systems in real-world industrial applications. That end-user input is now evident in the growing worldwide application of ISA-100.11a technology in processes including oil and gas, liquefied natural gas (LNG), refining, petrochemicals, chemicals, power, biopharmaceuticals, thermal processing, and water treatment.
In a presentation at the 2013 ARC Forum, for example, C. B. Chakradhaar of RasGas described the highly cost-effective application of ISA-100.11a-compliant wireless temperature transmitters to monitor a critical component in LNG production. Based on that success, he indicated, ISA-100.11a has been adopted as a plantwide standard for all future wireless applications.

The extension of ISA-100.11a to the IEC is the latest in a long and productive collaboration. Many original ISA standards have been adopted to become widely used IEC global standards in vital areas including:
- ISA-84/IEC 61511 Functional Safety
- ISA-88/IEC 61512 Batch Control
- ISA-95/IEC 62264 Enterprise-Control System Integration
- ISA-18/IEC 62682 Management of Alarm Systems
- ISA-99/IEC 62443 Cyber Security for Industrial Automation and Control
2013 ISA Standards & Practices Department awards winners
Each year, the ISA Standards & Practices Department recognizes significant contributions by standards committee members toward achieving major milestones-which typically would result in the publication of an ISA standard, recommended practice, or technical report. Six winners for 2013 were recently announced.
Hal Thomas of exida was recognized for his leadership and technical expertise as ISA84 Working Group 9 chairman in the development of ISA-TR84.00.09-2013, Security Countermeasures Related to SIS. The recently approved technical report is expected to be published in early December 2013. It provides guidance on the countermeasures used to reduce the likelihood of a security breach of a safety-instrumented system (SIS) that degrades its ability to perform its function. This relates to cybersecurity from both inside and outside the plant boundary.
The five additional winners of the award were recognized for leadership and technical contributions in developing the recently published ISA-TR106.00.01-2013, Procedure Automation for Continuous Process Operations - Models and Terminology. They are:
- Yahya Nazer, Dow Chemical Company, ISA106 co-chair
- William Wray, Bayer MaterialScience, ISA106 co-chair
- Marty King, Chevron Energy Technology Company, ISA106 past co-chair
- David Emerson, Yokogawa, ISA106 lead editor
- Charles Green, Aramco Services Company, ISA106 secretary
ISA-TR106.00.01-2013 addresses good practices for procedure automation in continuous process operations and strategies for incorporating automated procedures into industrial automation and basic process control systems (BPCS). The technical report complements the concepts in key ISA standards that deal with the use of procedures in specific applications, including batch processing (ISA-88) and safety systems (ISA-84). Many such fundamental concepts are common to all procedures without regard to the context in which they are implemented, but there are needs specific to continuous processes. These needs are addressed in a procedure requirements model, procedure implementation model, and physical model as well as in sections concerning mapping of procedures to BPCS components.
