Note: If the same event occurs once again, it will be displayed on the current event and alarm display
window according to the time sequence. The last event will become the history log and will disappear
from the current event and alarm display window, and this event can be found in history log. So, only the
event that occurs most recently can be displayed in the current event and alarm display window.
