Data dictionary
HEAT ProtoLib is the single home for the message reference: every entity, component and event message in the simulation data model, field by field, with types, units and enum values.
See HEAT ProtoLib › Message reference.
This page exists only as a pointer, so a search for “data dictionary” or “message reference” lands somewhere, and so no second copy of the field list drifts out of sync with the schema.
