6.2.2 Management Station Schedules Reference
This section provides background information for using management station
schedules. For related procedures, see Working with Management Station
Schedules [➙ 159].
6.2.2.1 Overview of Management Station Schedules and
Calendars
You can create daily or weekly schedules for your management stations, and a
management station can run multiple calendars or schedules at the same time.
Management station schedules and calendars run only if the management station
is running.
You can also create exceptions to schedules. When a management station
exception is ON, it overrides the weekly schedule. When the exception is OFF,
control returns to the weekly schedule.
Additionally, management station schedules can process both BACnet and non-
BACnet object types (BACnet schedules process only BACnet object types).
Management station schedules have only one binary output (value active or
inactive). You can assign several objects to that output. For each assigned object,
you can select the mode of action for the output value.
More About Management Station Schedules
Schedules consist of a name and description, a toolbar for working with the
schedule, a date picker, several tabs (Schedule Entries, Outputs, Exceptions, and
Setup), daily and weekly views, and schedule details.
More about Views
Even though you can schedule entries from the weekly view, the weekly view
shows only the resulting schedule and not the details of the schedule. For more
flexibility in visualizing and creating schedule entries, use the Schedule Entries tab
instead.
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 Schedule Behavior
When you select a management station schedule from System Browser, the Date
Picker defaults to the current date, and the Schedule Entries tab becomes active.
By default, the Scheduler initiates events scheduled in the management station
one second prior to the scheduled time. For example, if you set the value of an
output to change at 08:00:00, the logviewer will reflect a change at 07:59:59.
More About Management Station Calendars
Calendars allow you to override scheduled switch commands. In this sense, you
can consider calendars as exception schedules, consisting of dates only. When
you create a calendar, you can choose specific dates (January 15), a date range
(August 1 – 31), or a week and a day you want the exception to run (third week of
the month, on Wednesday). All calendars are associated with a schedule. For
example, if you want to reduce energy costs in your building during company
holidays, you can create a schedule with a calendar reference exception that
commands equipment into holiday mode.
