ACC

This component is a Config object that represents a Bacnet Accumulator object. The Accumulator object represents the characteristics of a meter that indicate measurements by counting pulses.

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.
Facets	Config window or read-only property	Identifies the units used for the current component or point value. These could be parent or child point facets.
Enable	`true` (default) or `false`	Activates (`true`) and deactivates (`false`) use of the object (network, device, point, component, table, schedule, descriptor, etc.).
Status Flags	read-only indicator and check boxes	Configures four status flags for BACnet. These options are available to enable detection of specific status conditions.
Event State	read-only	Reports the status of the event.
Out Of Service	`true` (default) or `false`	Affects the BACnet exposure and access of the source component only. In other words, if the source (exported) component is a proxy point, the equivalent `Enabled` property in its ProxyExt is not affected. `true` writes the point’s current value to the `Present Value` property. Often, a remote BACnet client sets (or clears) this Out of Service state. You can set this property to `false` if needed.
Scale	drop-down list
Max Pres Value	defaults to +inf
