A good HMI reduces mistakes under pressure. We draw on operator-centered HMI and alarm practices so screens stay readable, alarms stay meaningful, and navigation stays consistent across your line.
ISA-101 (HMI design)
ISA-101 promotes situational awareness — clear hierarchy, restrained color, and displays that help operators see process state instead of fighting flashy graphics.
How we follow it: We structure screens by task, keep color meaningful (not decorative), and prioritize the information operators need during normal run and upset conditions.
ANSI/ISA-18.2 (alarm management)
Alarm management guidance that treats alarms as a designed system: rationalized priorities, clear response expectations, and fewer nuisance floods.
How we follow it: We help define alarm intent, priority bands, and wording so operators get actionable signals instead of a wall of noise — and document assumptions for your team to own long-term.
IEC 62682 concepts
International alarm-system concepts that reinforce management of change, performance monitoring, and lifecycle ownership of alarms.
How we follow it: At a practical level we encourage measurable alarm performance, documented changes, and HMI presentation that matches your site’s alarm philosophy.
Operator accessibility & contrast
Plant floors are bright, dusty, and rushed — contrast, type size, and touch targets matter as much as the underlying PLC tags.
How we follow it: We specify contrast-friendly palettes, readable fonts, and navigation that works with gloves and glare, and we review screens with real operator workflows in mind.
Consistent navigation
Operators move faster when every machine and area follows the same wayfinding — overview → area → detail — with predictable controls.
How we follow it: We establish shared navigation patterns, faceplate conventions, and alarm acknowledgment behavior so training transfers across equipment.
