React Flow

Equipment-Centric View

Devices publish state to hierarchical topics following ISA-95 structure: Enterprise → Facility → Area → Line → Machine → Device

plant1/assembly/line3/robot2/state

Product-Centric View

Parts carry their own state machine as they flow through equipment. Each part tracks location, operation, quality, and complete genealogy.
