Glossary

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.
