To access this property expand, station Config > Drivers > BacnetNetwork > Config > Grp.

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

Property Value Description
Poll Frequency drop-down list (defaults to Normal) Selects among three rates (Fast, Normal and Slow) to determine how often to query the component for its value. The network’s Poll Service or Poll Scheduler defines these rates in hours, minutes and seconds. For example:

Fast may set polling frequency to every second.

Normal may set poll frequency to every five seconds.

Slow may set poll frequency to every 30 seconds.

This property applies to all proxy points.

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.

Object Type drop-down list of BACnet objects Reports the type of object.
List of Group Members list Represents a BACnet list containing a non-indexed sequence of objects of a particular BACnet data type.
Present Value (config group) list Represents a BACnet list containing a non-indexed sequence of objects of a particular BACnet data type.
