A plant is a logical unit of data that is normally used to model a single physical plant. A plant has a single plant hierarchy that defines the breakdown of the whole plant into its functional parts. Every object within a plant has a unique identity.
A plant makes use of a single data dictionary and a single set of reference data. Named objects are normally unique within a plant, but this is not a requirement.
A plant defines the largest scope of a report, and a plant can contain many P&ID drawings. Plant items such as equipment, instruments and pipes are shown in schematic form on the drawings.
