When you click with a file highlighted to export, the Add dialog (Figure 82) contains a number of fields with either default or empty values, described below.
All fields in this dialog apply separately to each highlighted (for export) file, as follows:
-
Name
Read-only Niagara component name for the Bacnet file descriptor, which defaults to the combination of:
file_<instance number>. -
Object Name
The “exposed to BACnet” name for this file. By default, only the filename and extension are used.
-
Object Type
Read-only reflection of the “BACnet Object type” exposed, in this case always:
File. -
Inst Num
The instance number portion of this object’s “Object ID,” which must be unique within the station for this (exported) BACnet File object type. By default, the export manager enforces this.
-
Export Ord
Station’s Ord location of the source file, using standard file Ord notation.
-
Description
Optional text string; this appears as the Description property value in the exposed BACnet object.
After creation (adding) Bacnet file descriptors, note that each descriptor also has additional properties accessible in its property sheet, along with those seen in the Add and Edit dialog. See the next section, Properties of Bacnet file descriptors for more details.
