Bacnet Numeric Schedule Descriptor (ServerNumSchedDesc)

This component exposes a NumericSchedule to BACnet as a schedule object. In the bacnet palette, it appears under the Server folder as ServerNumSchedDesc. However, you typically use the Bacnet Export Manager view of the BACnet Export Table to add, edit, delete, and access exported components.

You use the Bacnet Export Manager view of the Bacnet Export Table to add, edit, delete, and access exported components.

In addition to the common properties (Status and Fault Cause), this component has these properties.

Property Value Description
Scheduled Ord ord Configures the location of the schedule.
Object Id drop-down list and number (from 0 to 4194302)
Identifies each device and component by the type of entity (Object Id) combined with a unique Instance Number.

For devices (controllers, instruments, meters, etc.), Instance Number must be unique within the BACnet internetwork. For components (points, schedules, analog inputs, files, groups, multi state inputs, etc.), it must be unique within the device.

Object Name text in the format name.name.name.name (default includes the entire component path in the station using period (“/) delimiters between parent.child levels)
Identifies a BACnet object. This name should be unique within this specific device.

For components, this name includes the entire component path under the station’s Config using period (.) delimiters between parent.child levels. This enforces (externally) the BACnet requirement for unique names for all objects in a device.

For a proxy point, this is the default name in the station.

You can shorten or edit Object Name, however, each Object Name must be unique among all server descriptors under the Export Table.

List of Object Property References read-only
Provides a standard Bacnet ListOf sequence, which contains a non-indexed sequence of references related to the schedule.
Priority for Writing numeric text values 1 through 16
Reports schedule priority, which defaults to 16.
Description text
Provides additional information, which could include the camera’s geographical location or other unique information.
 NOTE: 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 window.  
Reliability read-only
Provides information when an error interrupts communication with a device.

No Fault Detected indicates that things are OK.

Unreliable Other indicates that the exported BACnet object appears in fault. This might happen, for example, if the source (exported) component is a proxy point under some other driver, and device communications are down or if the point has been disabled.

In this case, the BACnet export descriptor retains a status of ok.
