Today’s Schedule |
Contains the schedule timeline for the current day. The timeline displays the projected schedule output that will be written to the scheduled objects for the current day, combining the default Schedule Command with events from both the Weekly Schedule and Exception Schedule. Today’s Schedule also displays a table of times and values, which details the changes in the schedule’s output for the current day. Note: Today’s Schedule does not display in the SCT. It also does not
display for mapped third-party schedules.
|
Weekly Schedule |
Contains a timeline of events for each day of the week - Monday, Tuesday, . . . Sunday. Each event has a time and value that the Schedule writes to the scheduled objects. An event ends at midnight, but it can be ended earlier by specifying an end time or by scheduling another event to start. Events in the Exception Schedule override times and values in this Weekly Schedule. If the Weekly Schedule has no events defined on a particular day and time, and there are also no exception events scheduled, the Default Schedule Command takes effect. Note: Weekly Schedule does not display for third-party schedules that do
not support a weekly schedule.
|
Exception Schedule |
Contains a list of exceptions to the weekly schedule. The times and values in the exception replace anything that is in the weekly schedule. If more than one exception is scheduled on the same day, the highest priority (precedence) exception takes effect. If all exceptions are of the same precedence, they are executed in time order. Exceptions override the Weekly Schedule only when events are scheduled for the exception. Any time that an exception event is not in effect, such as when an event is ended before midnight (or no exception events are defined), the Weekly Schedule takes effect. If the Weekly Schedule also has no scheduled events at that time, the Default Schedule Command takes effect. Notes:
|
Scheduled Items |
Contains the list of items to be commanded by the schedule object. If empty, the Schedule does not directly command objects but its Present Value can still be used as an input to other logic, such as an Interlock or Control System. The online display also includes a Status Log that shows the status of the schedule’s attempts to control each of the scheduled items. If no objects are scheduled, the Schedule Output Type determines what type of command may be scheduled. |
