Bacnet Schedule Import Ext (bacnet-BacnetScheduleImportExt)

This component is a child extension of a schedule that is being imported from a BACnet device. The schedule in the remote BACnet device is the master. The driver periodically synchronizes its local copy by reading the appropriate values. You add BacnetScheduleImportExts using the Bacnet Schedule Import Manager view.

Figure 74. Bacnet Schedule Import Ext properties

This extension imports one or more remote Schedule and/or Calendar objects into a station as a read-only schedule component. You use these BACnet schedules or calendars in the station.

The BACnet property Priority for Writing is included, however, it means little in the station usage of this imported schedule.

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

Property	Value	Description
State	read-only	Indicates the condition of the BACnet schedule.
Last Attempt	read-only	Reports the date and time of the last attempted execution.
Last Success	read-only	Reports the last time the station successfully performed this function.
Last Failure	read-only timestamp	Reports the last time the system failed to perform this function. Refer to `Fault Cause` for details.
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.
Priority for Writing	numeric text values 1 through 16	Reports schedule priority, which defaults to 16.

Execution Time

This extension has four control-time trigger properties: Execution Time (Interval, Manual, Daily), Trigger Mode, Last Trigger, and Next Trigger. These properties are documented in the Niagara Drivers Guide
