ISA-101 High Performance HMI Design: Visual Hierarchy, Grayscale Schemes & Alarm Color Rules

Transform overwhelming 1990s 3D pipe SCADA screens into high-performance ISA-101 compliant interfaces: grayscale backgrounds, analog indicators, and situational awareness.

  • Normal running equipment should be depicted in muted neutral gray; bright colors (red, yellow) must be reserved strictly for unacknowledged alarms.
  • Raw numerical values force operators to perform mental arithmetic; analog bars showing normal operating bands provide instant visual context.
  • Level 1 displays provide overall facility health at a glance without cluttering control buttons.
