1. Create a periodic schedule (no span for this one unless you want to trigger a start AND stop at the periodic times).
2. From the SchedulGhost macros that were created when the plug-in was installed, copy the "Enable schedule" and "Disable schedule" macros to a new folder.
3. Configure those macros to control your periodic schedule: 4. Now create a second schedule in SchedulGhost. This one will be used to enable and disable the first schedule. In my scenario, where I wanted to start and stop at 0800 and 2300, the Start would be 08:00:00 and the Span would be 15:00:00 (HH:MM:SS). The "Start event suffix" will be used to generate an event to enable the first/periodic schedule at 0800 and the "Stop event suffix" to disable it at 2300, similar to Pako's screen cap:
Thanks again Pako for creating this plug-in and helping me understand its use.
