View and Edit BACnet Schedules at Runtime

Scheduler is able to display BACnet schedules that have been configured on a BACnet device and imported into Plant SCADA. This means you can read and write to schedule and calendar objects on a BACnet device at runtime using the Scheduler interface.

Note: Runtime View is not supported for BACnet schedule objects. It is recommended that you use the Configuration View when displaying BACnet schedules in Scheduler.

Schedules that were configured on a BACnet device will demonstrate the following when displayed in Scheduler:

• In the equipment tree, each schedule object associated with a BACnet device will appear as a branch.

• When a schedule object is selected in the equipment tree, the schedule entries that display will reflect the schedule configured on the BACnet device.

• Instead of specifying an equipment state change, BACnet schedule entries specify a value that can be interpreted by the BACnet device.

Exception schedules that were configured on a BACnet device will demonstrate the following when viewed in Scheduler:

• Exception schedules will appear on the Configuration View on a highlighted special day.

• Each exception schedule on the BACnet device is represented by a category in the Special Days View. The date or date range of the exception schedule will be shown as special days.

• Each calendar object will be available as a single category in the Special Days View.

• The Type field on the schedule entry properties will indicate if a schedule entry is a "weekly" or "exception" schedule.

  Note:
  • If the date range specified for an exception schedule or calendar object is excessively long, it can affect system performance. For this reason, only the first six months of a date range will display in Scheduler.
  • If the date range specified for an exception schedule or calendar object has a start date that is beyond three years in the future, it will not display in Scheduler.

You can make the following changes to BACnet schedule entries:

1. Edit the Start Time and End Time within the boundaries of a day (from midnight to midnight).

   A schedule entry will still end at midnight even if the specified End Time is later.

2. Edit the Value.

3. Delete a schedule entry.
