Creating a BACnet Schedule
Scenario: You need to create a weekly occupancy schedule in a field panel that controls when the lights turn on and off for a school building.
You also want to create a holiday calendar that is used as an exception to the schedule, so that the lights will stay off during the holiday break, when the building will be vacant.
Reference: For background information, see BACnet Schedules.

Prerequisites:
- System Browser is in Application View.
- You have configured both BACnet configuration as well as Schedule application rights. See BACnet Configuration in Application Rights for detail information.
Steps:
1 – Create Schedule Entries
- You have created a BACnet schedule containing a data point that you want the weekly occupancy schedule to control.
It is available in Schedules > BACnet Schedules in the System Browser.
- Select Applications > Schedules > BACnet Schedules > [BACnet schedule].
- Select the Schedule Entries tab and click New to add a new entry.
- Specify the time from when you want to start executing the schedule, for example, 6:00:00 AM, and select the Default check box.
NOTE: Leaving an entry set to Default means the schedule will command all objects to the Schedule Default.
- Click New to add a second entry.
- Specify the end time to stop the schedule execution, for example, 6:00:00 PM, and change the Default check box to OFF.
- Click Save
.
- The system saves the schedule settings.
2 – Create a Holiday Calendar and Add Entries
- From the Scheduler toolbar, click New
.
- Click New BACnet Calendar.
- In the Calendar Entries section, click New.
- In the Calendar Time Period section, select the Date range option and specify the start and end dates for the calendar in the Start date and End Date fields.
- Enter a name and the field device on which you want to save the calendar and click Save .
- The system adds the calendar to the BACnet Calendars node in the Application view.
3 – Create an Exception
- In System Browser, select Applications > Schedules > BACnet Schedules > [BACnet schedule].
- Navigate to the Day/Week view, right-click the BACnet schedule and select Add Exception.
- In the Exception Period section, select Calendar.
- From the Calendar drop-down list, select the HolidayBreak calendar.
- In the Exception Times section, delete one of the two entries.
- In the remaining entry, enter 6:00:00 AM.
- Clear the None check box.
NOTE: Creating an entry with the default check box checked returns control to the weekly schedule.
For example, you might want to override the schedule for one hour at 1 P.M., so you create an entry at 1 P.M. with the override value.
Then, you create an entry at 2 P.M. with None checked. Control will return to the weekly schedule at 2 P.M.
- Select OFF from the drop-down list.
- The system creates an exception.
