Property Value Description
Poll Frequency drop-down list (defaults to Normal)
References the On Demand Poll Scheduler rates under the NiagaraNetwork’s History Policies container slot.

Configures how often this type of poll occurs.

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.
