The second paper of a two-part white paper series, "Maximize Operator Effectiveness," provides new case studies and guidelines on developing a detailed plan of action for the improvement of a process control HMI. This white paper augments the detailed content in The High Performance HMI Handbook.
In part two, we include two case studies. Two standards documents available on HMI are also discussed, including the ANSI/ISA-101.01-2015: Human Machine Interfaces for Process Automation Systems released in August 2015. The work process for HMI improvement is described, and we address the most common issues encountered in HMI improvement and cost effective ways to transition to High Performance graphics.
