EVENTS (AVAILABLE IN OPTION 1 AND OPTION 2 MODELS)
The MIF stores a historical record with the last 32 events. Each event contains the event description, date and time (4
ms accuracy), the current values in phases and ground at that moment, and a summary of the status signals that can
produce events, and whether they were activated or not in that moment.
In the ENERVISTA MII SETUP there is a field called “EVENTS”, where the user can check how many events have
been produced since the last time that Events where deleted. If this number is higher than 32 (maximum number of
events stored), this means that from all the produced events, only the last 32 are stored.
This event record is stored in a
capacitor backed up RAM memory
.
The whole MIF functionality related to events is performed from the ENERVISTA MII SETUP software.
Inside the ADVANCED SETTINGS group, there is a sub-group called EVENT MASKS, from where the different
causes that can produce events can be masked. They are detailed in the SETTINGS section.
The following table shows a list of all possible events:
