Structure introduces many notions with unfamiliar terms (genealogy, graph theory, etc.). This page summarizes the different concepts that are discussed in the documentation and provides links to the respective documentation.
AntiInfoSource
Indicates that no InfoSource should be added to a component containing an AntilnfoSource
Ascendant
Ascendant of a node with a direct or indirect isln relation
Aspect
Point of view used to describe a source. See the Aspect documentation
BreadCrumb
Horizontal menu to describe a path in a tree
DefinitionSet
Characterize an aspect in which a node represents all the entities in an abstract manner (e.g. ACU. The node does not represent a particular ACU)
Descendant
Child of a node with a direct or indirect isln relation
DeviceDefinition
SystemDefinition dedicated to the Niagara Device
EntitySet
Characterize an aspect in which a node represents a single entity, often real (e.g.: Building A. There will be as many nodes named Building A as there are buildings A in a site).
InfoSource
A Niagara component becomes a source as soon as an InfoSource is added to it
isIn
The isln relation
isInMultiple
The isInMultiple relation between two NodeDefinitions allows a node to be added to two parent nodes. (Typical example, duplex apartment belonging to two floors)
NetworkDefinition
SystemDefinition dedicated to the Niagara network.
Node
The Node represents a physical entity (Floor 1) or abstract (Temperature, Accounting Service).
Orphan Nodes
An Orphan Node is a node with a level greater than 1 that does not have ascendants on the isln relation.
NodeDefinition
The NodeDefinition makes it possible to group or generalize Nodes of the same "type" by creating a common definition
NodeGroup
The NodeGroup represents a group of nodes of the same aspect and allows sources to directly affect multiple nodes
NodeGroupDefinition
The NodeGroupDefinition makes it possible to group or generalize Nodes of the same "type" by creating a common definition
NodeRelation
The NodeRelation allows a relation between a node and another component of the station to be defined. This relation is defined when the node is created through the NodeCreator.
NodeTag
The NodeTag is used to define the addition of a tag to a node when it is created. This tag is presented to the user when the node is created through the NodeCreator.
PointDefinition
SystemDefinition dedicated to the Niagara ControlPoint.
PointFolderDefinition
SystemDefinition dedicated to the Niagara PointFolder.
Siblings
Siblings are defined as two nodes with the same parent node (a kind of brother & sister). Two sibling nodes cannot have the same displayName in Niagara.
Source
A source is an existing element of a station: a point, a point file, a device, a time schedule, etc.
SourceRelation
SourceRelation defines a possible relation between a source and another of the station's components. This relation is defined when the source is assigned to a node through the AssignmentView.
SourceTag
The SourceTag is used to define the addition of a tag to a source when assigning a source to a node through the AssignmentView
StationDefinition
SystemDefinition dedicated to the NiagaraStation (Niagara station of the Niagara Network).
SystemAspect
The System aspect is an aspect dedicated to SystemDefinition and makes it possible to describe the system architecture of a source.
SystemDefinition
The SystemDefinition is a generalization of a Niagara type. It does not contain nodes, the sources play the dual role of source / node in this case.
TopNode
A TopNode is a node that does not have a parent. It is level 1.
