①
Describing the relative position of a point or equip in the hierarchy
References in relative bindings always start at lower levels of the building hierarchy and link to higher
levels. For example, references link from a point (or shadowPoint) to an equip to a site to the Desigo
Control Point device at the Root .
②
Dynamic structure
Relative bindings create a structure that is used to dynamically identify a point or equip. In this
example, relative bindings link the Heating coil valve position (point or shadowPoint) to the Heating coil
(equip) ③, which is linked to the Automation station view (equip) ④ and then linked to the Default site
(site) ⑤.
③
Equipment assets
● The equip tag can be used in multiple levels of the building hierarchy. In this example, the Heating
coil, Supply air VAV and Automation station view have equip tags.
● Additional tags may be available to uniquely identify the function of each object. For BACnet/IP
systems, the ability to identify the function of an object depends on the conventions used in your
application engineering.
For more information, see Additional object properties in the Plant view Tools [➙ 34] section.
④
Site level of the building hierarchy
⑤
Root of the database
The top-most level of the building hierarchy for all devices being monitored. This special object is
tagged topLevel. Graphics may be assigned to display at this location, but you cannot access or
modify the tags at this level of the hierarchy.
For more information, see GRAPHIC ON binding query [➙ 62].
GRAPHIC ON binding query
The GRAPHIC ON binding query determines where the graphic displays in the building hierarchy. The query
can be manually modified to best identify the building hierarchy object(s) on which the graphic may be loaded.
● For graphics with absolute binding, the GRAPHIC ON can be set to any specific Object name or point ID in
the database. No matter where the graphic is opened for viewing, the bindings always connect to the same
object instances.
● For graphics with relative binding, the GRAPHIC ON query acts as a filter to determine which site or equip
the objects in this graphic can target when opened for viewing.
– When the graphic is opened, the graphic components connect to the object instances that reference this
target object . This function allows one graphic to be reused for other target objects in the building
hierarchy that have the same or similar structures.
– The $id variable in each relative binding query dynamically assumes the value of the site (for example, a
building) or the equip (for example, an AHU plant) where the graphic is opened for viewing. That is, the
target object .
– In Desigo Control Point, the root of the GRAPHIC ON query is expected to be an equip. To create
graphics at the site level or Root of the project, see the Creating site and Root level graphics [➙ 65]
section.
– When saving a graphic, consider where it should be available within the building hierarchy. For example,
equip and navName==”Plant01” or navName==”Plant02” makes a graphic available for opening and
reuse at multiple locations in the building hierarchy. Alternately, the query string topLevel makes a
dashboard graphic available at the Root of the project.
