Elements of a Control Application Chapter 8
Scheduled and Unscheduled Programs
The scheduled programs in a task execute to completion from first to last.
Programs that are not attached to any task show up as unscheduled programs.
Unscheduled programs in 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 in 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.
