ISA 101 Committee
Committee formed in 2006 to establish standards, recommended practices, and/or technical reports for designing, implementing, using, and/or managing human machine interfaces in process automation applications
ANSI/ISA-101.01-2015 Human Machine Interfaces for Process Automation Systems• Approved July 9, 2015
Over 300 Voting Members • Integrator, Engineering & Construction 35%• End User 27%• Vendor/Supplier 25%• General (Academic, Government, Consultant etc.) 13%
• Worldwide participation in review process
-
The Purpose of ISA 101
Address the design, implementation, and maintenance of human machine interfaces (HMIs) for process automation systems, to:
• Provide guidance to design, build, and maintain HMIs which result in more effective and efficient control of the process, in both normal and abnormal situations
• Improve the user’s abilities to detect, diagnose, and properly respond to abnormal situations
• Look at the HMI holistically – not just the display
Standards are the “What”Technical Reports and Recommended Practices are the “How”
-
Who Cares About HMI Standards
Users• Responsible for safe and productive operation of equipment and facility• Live with the HMI and support it for it’s lifetime
Integrators, Designers, Engineers• Design and build the HMI applications • Commission the HMI, and the associated process
Suppliers• Develop the software and hardware needed to build the HMI• Develop the interfaces/drivers needed for an HMI to transfer data and information
to and from multiple sources
-
ISA 101 Working Groups
WG1 - HMI Philosophy & Style Guide Development• This technical report will describe example applications of the Philosophy and Style Guide to
various Process Automation Systems use cases, and will be platform independent (41 members)• Co-chairs; David Lee and Lothar Lang
WG2 – HMI Usability and Performance• This technical report(s) will be used to assess the effectiveness of the HMI application, and how
the use of the standard will assist in improving related metrics (29 members)• Co-chairs; David Board and Ruth Schiedermayer
WG3 – HMI for Mobile Devices• Develop technical report(s) to evaluate and define the use of mobile devices as HMI stations and
how to effectively implement an HMI for use on a mobile device (21 members)• Co-chairs; Mark Nixon and Peder Brandt
WG4 – HMI for On-Machine Applications• Develop technical report(s) to effectively implement a machine-level HMI utilizing an operator
interface terminal• Co-chairs; Arlen Jacobs and David Board
