BacnetEventLogImport

This component defines the archive action to retrieve data from a BACnet Event Log object into a history created by the addition of this component. It functions in a Supervisor station and is available only from the bacnetAWS palette.

Figure 153. Bacnet Event Log Import

To access these properties in a Supervisor station, expand the BACnet network and device, double-click the Trend Logs folder () and expand the BacnetEventLogImport component. If no import component is present, open a bacnetAWS palette, expand Trending > Client Trending, and drag a BacnetEventLogImport component to the Trend Logs folder.

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

Property	Value	Description
Execution Time	multiple properties	Configures the frequency with which data are imported from a remote trend log (or trend log multiple) into a history (or histories). Data import may occur at regular intervals (`Interval`), `Daily` or when manually requested (`Manual`). `Time Of Day` specifies a specific daily time. `Randomization` configures an import based on time. `Days Of Week` specifies on which days to apply the import time.
Last Attempt	read-only	Reports the date and time of the last attempted execution.
Last Success	read-only	Reports the last time the system failed to perform this function. Refer to `Fault Cause` for details.
Last Failure	read-only timestamp	Reports the last time the station successfully performed this function.
History Id	read-only	Displays a combination of the station name and history name.
On Demand Poll Enabled	`true` (default) or `false`	Enables and disables polling of both local history sources and history imports for live data. The reported data appear on history charts and in history table views.
On Demand Poll Frequency	drop-down list	Configures how often this type of poll occurs.
Config Overrides, capacity	drop-down list (defaults to `Unlimited`)	Defines the maximum number of history records allowed in the associated table. `Unlimited` enforces no limitation on the number of records. `Record Count` opens an additional property for defining the table limit.
Config Overrides, fullPolicy	drop-down list (defaults to `Roll`)	Defines what happens if `Capacity` is set to `Record Count` and the specified record count is reached. `Roll` overwrites the oldest records with the newest ones. This ensures that the latest data are recorded. `Stop` terminates recording when the number of stored records reaches the specified capacity. Full policy has no effect if `Capacity` is `Unlimited`.
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.
Local History Name	read-only	Reports the name of the local history component.
Local History Name Format	text, BFormat (Baja Format) syntax (defaults to `%name%`, which recreates the BACnet name of the trend log object) or a combination of text and BFormat.	Defines the format string script for returning a local history. This is the name of the history initially created and populated by the trend log data and includes, typically, the name of the BACnet device component and the BACnet trend log object. For example: %parent.parent.displayName% %name% could define the name of a VAV fan: J7Bnet BldgA_VAV1_Fan. You can modify the default BFormat with other BFormat scripting. You could enter static text for the history name—or, some combination of static text and valid BFormat scripting text. In the case of trend log multiples (BacnetTrendLogMultipleImport), the default `%name%` value results in histories named using the BACnet name of the trend log multiple object, with underscore delimiters between the BACnet names of each _object_property record.
Reference Time	hours, minutes, seconds	Defines the timestamp the system uses to include records in the trend log.
Max Records Per Request	0 (default) to `max`	Defines the maximum number of records that can be archived in this trend log. The Framework asks for 10 records per request.
Always Request By Reference Time	`true` or `false` (default)	Configures if the driver should always use the `Reference Time` to request records.
Last Sequence Number Processed	number	Defines a maximum record number to process.
Local History Names	read-only	Reports the name of the local history component.
