Defaults and rules
The following defaults and rules apply when you engineer the object name in the XWP Hierarchy Viewer:
● The Free Designation (FD) can be max.69 characters.
● Only ISO-Latin-1 code points from [32..127] and [160..255] may be used. This excludes all characters
from [0..31] and [128..159]. These ISO-Latin-1 code points are identical to Unicode code points.
● No lead or post blanks [32] may exist and object names containing only blank characters are not
possible.
The FD values and the object name selection are transferred automatically to the automation station or
exported to the management platform during compiling or loading in the CFC.
The CFC Editor checks during compilation if the object name is unique for each automation station under
the following rules:
● The same resulting object name may exist only once per automation station. This also applies to the
device object that must be unique in the BACnet internetwork.
● The resulting object name may not correspond to a TD of another object in a Device. The TD is used to
resolve BACnet references.
Exceptions for object name assignment
Object names cannot be engineered in CFC charts or compounds. These elements always define the TD
and the object name is always the same as the TD.
Special blocks, such as Heatcurve and Discipline I/Os generate reduced value objects in the background
whose object name per default is the TD during compilation.
Free definition of the Device ID
The device ID (the object ID of the device object) can be freely defined. Range: 0…4'194'303
