New ISA101 HMI technical report focuses on usability and performance

摘要

The purpose of having an automated process is to enhance process operations based on safety, performance, process improvements, availability, repeatability, and other relevant factors. Human-machine interfaces (HMIs), the primary means by which users interact with a process, provide the potential and opportunity both to greatly facilitate and enhance operations or to otherwise confuse users and degrade operations. ISA's first human-machine interface (HMI) standard, ANSI/ISA-101.01-2015, Human Machine Interfaces for Process Automation Systems, covers the philosophy, design, implementation, operation, and maintenance of HMIs for process automation systems, including multiple work processes throughout the HMI life cycle. It defines the terminology and models to develop an HMI and the work processes recommended to effectively maintain the HMI throughout the HMI life cycle, including all general concepts until its decommissioning, applying a practical and management approach. The target audiences include end users, designers, developers, and implementers of HMI systems.
