Although the Action Calendar will normally provide for all of your event scheduling needs, there are two instances where you should use other CIMPLICITY tools:

1. If you want to schedule an event to execute every minute, use the CIMPLICITY Event Editor. The Event Editor provides an easier way than the Action Calendar to schedule these types of repetitive events.

2. If you want to schedule an event in less than one-second real time intervals, use a PLC or a CIMPLICITY PC control to perform the real time control. In the Action Calendar, events can be scheduled to the second. On a normally loaded system, your event will execute within +1 second of the target time.
