To display different plants in a uniform manner, a standard hierarchical plant structure has been created for each plant type.

Primary plants with Desigo PX

Structure

Elements

Site: A site is a self-contained area in terms of location, function and organization, usually a building or a group of buildings (facility). A site can comprise several plants. Example: Building 6

Plant: A plant consists of partial plants, aggregates and components. A plant can comprise several partial plants. Aggregates and components can be directly subordinate to a plant. Example: Ventilation system, heating system

Partial plant: A partial plant can comprise various aggregates. Components can be directly subordinate to a partial plant. Example: Central supply air treatment, air distribution, hot water supply (one or more boilers)

Aggregate: An aggregate can comprise various components. Example: Exhaust air fan

Component: A component can comprise several components, which can comprise several components themselves. Example: Pumps (motors), dampers, valves, sensors, detectors, limit switches, contactors, selector switches, remote/local switches

Global objects

Structure

Elements

Site: A site is a self-contained area in terms of location, function and organization, usually a building or a group of buildings (facility). Example: Building 6

Global area: The global area contains all the global components of the site. There is one global area per site.

Global objects are data objects which exist simultaneously in several automation stations at the automation level, e.g., an exception calendar for the time schedules of all plants. These objects are combined as a virtual system in a global area and can be invoked as such.

Component: A global area may contain several components, such as 3 calendars, 18 notification classes for alarm distribution. Each component is present on all automation stations of the site. For operation, however, each component is visible only once.

Structure

Elements

Site: A site is a self-contained area in terms of location, function and organization, usually a building or a group of buildings (facility). A site can comprise several plants. Example: Building 6

Area: An area is typically a building, and can comprise subareas, sections, components and subcomponents. Example: Building

Subarea: A subarea is typically the wing of a building and can comprise several sections. Rooms can be directly subordinate to a subarea. Example: Building wing, staircase

Section: A section is typically a floor in a building and can contain various rooms. Example: Floor

Software objects, which need to be displayed and operated even though they do not exist as physical elements in a real building, are also treated both as sections (e.g., via grouping criteria, such as east facade or emergency group 12) and as components (e.g., group object for distribution of centrally determined control variables to several rooms).

Room: A room is a section of a building that is delimited by walls, ceilings, floors, windows and doors. Example: Individual room, hall

Room automation with Desigo room automation

Structure

Elements

Building: A building is a locally, functionally and organizationally defined area. Example: Building 6

Floor: A floor in a building can contain various rooms. Example: Floor

Room: A room is a section of a building that is delimited by walls, ceilings, floors, windows and doors. Example: Individual room, hall

Room segment: A room segment is a subdivision of a room. A room can contain several room segments.

Functional unit: A functional unit is a logical component representing an encapsulated application unit which may be independently deployed to an arbitrary automation device. Example: Fan coil

Component: A functional unit can contain several components. Example: Awning
