Scheduled and Unscheduled Programs
The scheduled programs within a task execute to completion from first to last.
Programs that are not attached to any task show up as unscheduled programs.
Unscheduled programs within a task are downloaded to the controller with the
entire project. The controller verifies unscheduled programs but does not execute
them.
You must schedule a program within a task before the controller can scan the
program. To schedule an unscheduled program, use the Program/Phase Schedule
tab of the Task Properties dialog box.
