Event management status. Currently, the system supports two states. Options: 1. init(1) -During the setting operation, you can change only the event that is in the initial state to the alarm but cannot change an alarm to an event. Therefore, init(1) can be implemented only through the getting operation to check whether the current state is initial. 2. conversion(2) -If an event needs to be converted into an alarm, perform the setting operation through conversion(2).
