A schedule is a sequence of events that determines when essential events occur in a building automation system: doors locking or unlocking, temperature raised or lowered, or equipment turned on or off.
For example, the lighting in an office building needs to be automated to conserve energy during non-business hours. To regulate the lights from Monday through Friday, you create a weekly schedule that turns the lights on at 07:00 and switches them off at 20:00. If there are any non-routine events, such as holidays, you can use exception events to override the schedule and turn the lights off. For more information, see Exception Events in WorkStation .
You use the Schedule Editor to create and manage schedule events for digital, multistate, and analog schedules. The schedule events that you create can be weekly events or exception events. A weekly event recurs on a weekly basis. An exception event defines either a one-time change or a recurring change that overrides the standard weekly events. In the Schedule Editor, you can view the schedule events in Basic view or Advanced view.

Priority is a number that corresponds to a preassigned level of importance. When used in schedules, priority numbers range from one to sixteen. One is the most important or highest priority and sixteen is the lowest priority.
For more information, see Priorities .
You can create three types of schedules: Digital, Multistate, or Analog. You create a digital schedule if the schedule needs to control a device with two output states, such as On or Off. You create a multistate schedule if the schedule needs to control a device that has output states based on multiple states, such as low, medium, or high. You create an analog schedule if the schedule controls a device that gauges the output in real numbers.
For more information, see Schedule Types .
A schedule has two types of events: weekly events and exception events. Weekly events occur every week at specified times. Exception events occur when the schedule deviates from the weekly schedule, such as during holidays. Exception events override the weekly events when there is an overlap.

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.
For more information, see Calendars in WorkStation .
When you configure a schedule that controls events in a single part of a building, you might also want the same events to occur in other areas of the building. You can establish a lead and shadow relationship to synchronize the events in schedules and dates in calendars.
For more information, see Schedule and Calendar Synchronization .
A binding is a connection between two or more variables for data exchange. In its simplest form, a binding consists of a source and a destination. The destination reads the value from the source.
