Human Machine Interface (HMI) has evolved significantly from the days in which operations staff had to sit in front of a single screen to monitor a machine or a process. HMI/SCADA (Supervisory Control and Data Acquisition) applications now not only monitor and help control equipment and processes but also provide a huge range of information [...]

In the ISA Automation Week Mentor Program, I am providing guidance for extremely talented individuals from Argentina, Brazil, Malaysia, Mexico, Saudi Arabia, and the USA. We will be sharing a question and the answers each week. If you would like to provide additional answers, please send them to Susan Colwell at ISA. The twentieth question [...]
Poor HMI designs have been identified as factors contributing to abnormal situations, billions of dollars of lost production, accidents, and fatalities. Many HMIs actually impede rather than assist operators. Many of the poor designs are holdovers due to the limitations of early control systems and the lack of knowledge of system designers. However, with the [...]
The need for standardization led the City of Guelph’s Water Services department in Canada to embark on a multi-year program to modernize and enhance its Supervisory Control and Data Acquisition (SCADA) system using a standards-based approach. Starting with a comprehensive SCADA Master Plan, the city developed a set of SCADA standardization documents that were incorporated [...]
This real-world-based course will give you a broad introductory understanding of the specific issues involved with Building Automation Systems (BAS). You will explore the processes that occur at every level in the air conditioning industry including digital controls. Learn about sensing and measurement, actuation, analog output devices, and relays. Computer interfaces are discussed including web interfaces. Your survey of the world of BAS includes: Future of BAS; Digital Direct Control (DDC) Basics; Field Devices; The Human Machine Interface (HMI); BAS Design and Specification; Energy Conservation Control Strategies; and System Maintenance.
The human-machine interface (HMI) is the software application running in the operator consoles that permits operators to visualize the process. This course will provide an introduction to the primary aspects of HMI configuration: best practices in information presentation for process equipment, text, numbers, historical trends, and alarm information. Presentation of related on-demand information, including reports and links out to other documents will be covered. A basic overview of best practices in scripting will also be provided.
This course focuses on the key activities of the alarm management lifecycle provided in the ANSI/ISA18.00.02 standard, Management of Alarm Systems for the Process Industries. The activities include the alarm philosophy development, alarm rationalization, basic alarm design, advanced alarm techniques, HMI design for alarms, monitoring, assessment, management of change, and audit.
The High Performance HMI Handbook by Bill Hollifield, Dana Oliver, Ian Nimmo and Eddie Habibi, the industry’s most popular human-machine interface (HMI) resource book, shows how proper HMI design can increase profitability, quality and safety, and eliminate many critical factors that contribute to major industrial accidents and process upsets.
Alarm Management: A Comprehensive Guide, Second Edition, by Bill R. Hollifield and Eddie Habibi, outlines a practical seven-step approach to implementing alarm management that’s been proven effective in hundreds of actual projects across dozens of different companies and industries.
