The Need for HMI Standards

• Many have suggested the need to ISA in recent
  years.
• Survey revealed high interest from user
  companies, vendor companies, and consultants.

3
Commonly Cited Benefits from this Input

• Reducing operator mistakes and misinterpretations
  via clear and intuitive representations of
  conditions and operator control interfaces.
• Reducing learning curves for new operators, and
  allowing operators to move from one system to
  another (often within the same plant) with
  minimal retraining.
• Assisting communications and reducing errors
  between geographically dispersed groups.
• Reducing costs of re-invention.
• Reducing rework because differences in design
  philosophies could be solved up front.
• Enabling applications to be developed using HMI
  features that will be supported in future systems
  and HMI upgrades.

4
Potential Challenges

• Many believe large user companies will benefit
  the most and thus will drive HMI standards
  development -- but not without some potential
  challenges resulting from
• Legacy equipment from a multitude of vendors
  including equipment from the same vendor but
  across generations with users wanting to avoid
  re-wiring, re-installing, and re-training.
• User company devotion to existing internal HMI
  standards/preferences including a belief by
  some that internal standards may provide a
  competitive advantage.
• Some vendors may prefer non-standard HMIs as a
  way of keeping existing customers.

ISA-SP101 Up and Running

• Weighing the pros and cons, ISAs Standards
  Practices Board voted to approve ISA-SP101,
  Human-Machine Interface Standards, in July 2005,
  and appointed
• Co-Chair John Shaw, Process Control Solutions,
  Rochester NY.
• Co-Chair Joe Bingham, Advanced Process
  Solutions, Commerce CA.
• Managing Director (representative on SP Board)
  Dr. Angela Summers, SIS-TECH Solutions,
  Houston TX.

ISA-SP101 Purpose and Scope

• Pending approval by the ISA Standards Practices
  Board
• Purpose Establish standards, recommended
  practices (RPs), and/or technical reports (TRs)
  pertaining to human-machine interfaces in
  manufacturing applications.
• Scope The standards, RPs, and/or TRs will be
  directed to those responsible for designing,
  implementing, using, and/or managing
  human-machine interfaces in manufacturing
  applications. Unless noted otherwise in a
  specific ISA-101 document, the documents will
  apply to all manufacturing industries..And ?

ISA-SP101 Scope (continued)

• Areas covered will include (subject to change.)
• menu hierarchies
• screen navigation conventions
• graphics and color conventions
• dynamic elements
• alarming conventions
• security methods and electronic signature
  attributes
• interfaces with background programming and
  historical databases
• popup conventions
• help screens and methods used to work with alarms
• program object interfaces
• configuration interfaces to databases, servers,
  and networks.
