Adding a Calendar Exception Event

You add a calendar to the schedule to make an exception event for all dates specified in the calendar.

Show More

A calendar is a list of dates. The calendar provides the schedule with the dates when the exception events shall occur. To save time, you can reference a single calendar rather than entering several exception events in a schedule.

Exception events in a calendar

Many schedules can make a reference to the calendar. You can define the group of dates once rather than over and over again in multiple schedules, a potentially tedious task if your building control system contains many schedules.

Calendar Editor Overview

You use the Calendar Editor to create a calendar that contains a date list of exception events. The exception events can be a single date, a date range, or a recurring date. By using a calendar, you specify all the exception events only one time, rather than in each schedule. The calendar is then referenced to each of the schedules and all exception dates are automatically designated in the schedules.

For more information, see Calendar Editor Overview .

Calendar Events

The dates specified in a calendar are shown in the date list. You can specify dates in a calendar by three different methods:

  • Date: a specific date

  • Date range: a fixed period with a set start and stop date

  • Calculated date: a fixed period that repeats

For more information, see Calendar Events .

  1. In WorkStation, in the System Tree pane, select the schedule you want to add the calendar to.

  2. Click the Basic tab.

  3. On the Basic Schedule Editor toolbar, click the New schedule event button


  4. In the Schedule Event Properties dialog box, click Exception .

  5. Click Calendar .

  6. Select All Day if the exception event is to be on or off all day.

  7. In the Start Time column, type a start time for the exception event.

  8. In the End Time column, type an end time for the exception event.

  9. In the Value column, select a value for the exception event.

  10. In the Name box, type a name for the exception event.

  11. In the Priority box, select a priority for the exception event to make it override conflicting events with lower priorities.

  • You cannot specify different times and values for each of the different dates. All dates specified in the calendar must have the same times and values assigned to them.
