• HMI draft gains initial approval in ISA101 ballot

    ISA-d101.01, Human Machine Interfaces for Process Automation Systems, was approved in a first ballot closing June 24, 2014 by ISA101, Human Machine Interface. Review comments received during the ballot were reviewed by ISA101 at a July 1-2, 2014 meeting in Raleigh, NC in conjunction with the ISA Leaders Meeting. Based on that review, the draft may be submitted for final approval by the ISA Standards & Practices Board, or revised and issued to ISA101 for another committee ballot.

    The draft standard addresses HMIs for equipment and automated processes, providing information, guidelines and a methodology to enable users to be more effective in yielding improved safety, quality, production and reliability.

    The practices in the document are applicable to continuous, batch, and discrete processes, and indeed to any process using an HMI for interfacing to a controlled system.  There may be differences in implementation to meet the specific needs based on process type.

    ISA101 is co-chaired by Greg Lehmann of URS Corporation and Maurice Wilkins of Yokogawa. For more information on ISA101, contact Linda Wolffe of ISA Standards, lwolffe@isa.org.
