ISA84, Instrumented Systems to Achieve Functional Safety in the Process Industries

Three ISA Standards & Practices Awards were presented during the ISA84 plenary meeting during the week of 17 October, hosted by SIS-Tech in Houston, Texas, US. The awards recognize leadership in developing three of the series of ISA84 technical reports that aid in the understanding and application of the series, ANSI/ISA-61511, Functional Safety – Safety Instrumented Systems for the Process Industry Sector:

  • Angela Summers – For outstanding leadership and technical expertise in the revision and update of ISA-TR84.00.02-2022, Safety Integrity Level (SIL) Verification of Safety Instrumented Functions
  • Kevin Klein – For leadership in the revision and update of ANSI/ISA-84.91.01-2021, Identification and Mechanical Integrity of Process Safety Controls, Alarms, and Interlocks in the Process Industry Sector 
  • David Bennett – For leadership and expertise in the update of ISA-TR84.00.04-2022, Guidelines for the Implementation of ANSI/ISA-61511

ISA18, Instrument Signals and Alarms

ISA18 co-chair Donald Dunn will join Cristobal Ruiz as co-chair of working group 1 to lead a revision of ISA-18.1, Annunciator Sequences and Specifications. This standard establishes uniform annunciator terminology, sequence designations, and sequence presentation. Watch for more information on the work and plans of ISA18 in the December InTech magazine. 


ISA99, Industrial Automation and Control Systems Security

Long-time ISA99 co-chair Jim Gilsinn has stepped down from that role but will remain active in the committee. Johan Nye will join Eric Cosman as the new co-chair. Learn more about ISA99 and ISA/IEC 62443 standards and activities.


ISA5, Measurement & Control Instruments and Systems

ISA5 is conducting its first ballot on ISA-dTR5.9, Proportional-integral-derivative (PID) Algorithms and Performance. This technical report documents common PID algorithms used in industrial control systems, including the implementation methods, options, and performance measurements of the various algorithms.
