Default Date
By default, every new schedule begins with the current date and never ends. Once
a new schedule is opened, you can choose the start and end date for the schedule.
Default State
By default, the system automatically creates weekly schedule entries for the default
state, which you can modify. The
Release (NULL) check box allows you to bypass
the established priority and return an object to its default value. For example, to
return control to lower priority commands, check the
Release (NULL) check box for
the schedule default, and then create a schedule entry with the
Default check box
checked. This will write BACnet null to the priority slot for the schedule, returning
control to the system.
Default Schedule Behavior
When you select a BACnet schedule from System Browser, the Date Picker
defaults to the current date, and the
Schedule Entries tab becomes active.
About Priorities
The Present Value of some object types is based on a command priority and
established in a hierarchy that ranks from highest (1 – Manual Life Safety) to lowest
(16 - Available). The hierarchy determines which source has priority over another
to change the value of an object. To command one of these object types, you—or
an application—must have a command priority equal to or greater than the current
command priority of the object. . Typically, PPCL is set to priority 16, and
schedules are set to priority 15.
