Using the Scheduler
Schedules are spreadsheets with separate tabs for event-based entries and time-based entries. Double-clicking an empty row in a schedule displays a dialog box for adding an entry. Once you have created an entry, you can edit individual cells in the spreadsheet without using the dialog box.
Time-based entries create a timer object while event-based entries create an event object. These iFIX objects have associated properties, methods, and events that you can use in VBA scripts. They are displayed in the system tree and are the objects to which scheduled scripts are tied.
