Ian discusses what high-performance HMI is. Most people only use HMI, resulting in over-using colors, glaring screens, and information being displayed incorrectly. Our retention is focused on how an operator detects a problem. We want to be able to detect the moment we leave normal operation. We need to define what is off normal, which is long before we get into the abnormal area (an alarm state) and then the emergency situation. Graphics are used for normal operation and alarms for off-normal. If this isn’t done correctly, it will be difficult for the operator to respond, which will result in the operator being very overwhelmed.
