On the Schedule tab the time interval for the task can be defined.
Active : Define if the task is active. When the task is not active, the scheduler application will not check this task.
Exclusive Start : Define if the task should run without any other task running. By default tasks run in parallel.
Start Datetime : Define the date on which the task should run for the first time.
Interval : Define the frequency of the current task. Please note that if this frequency is set higher (more often) than the Scheduler application is triggered by the Windows Scheduled Task, the frequency of the scheduled task will be the effective interval.
Next Run Time : Shows when this task will run for the next time.
