All events are recorded in the Event Log , such changes of state in a point, a transfer, user login, or an alarm.
The Event Log has 512 entries.
Alarms are specific events listed on the Alarms screen and also recorded in the Event Log .
The STS also records input and output waveforms for selected events, such as transfers or outages that can be
viewed in the
Plots screen.
In case of power loss, the STS can continue recording events for approximately 15 seconds, providing
diagnostic information.
