The internal events in this list not only refer to faults in the IED, but also to other
activities, such as change of settings, clearing of disturbance reports, and loss of
external time synchronization.
The information can only be retrieved from the Parameter Setting software package.
The PC can be connected either to the port at the front or at the rear of the IED.
These events are logged as internal events.

The events in the internal event list are time tagged with a resolution of 1ms.
This means that, when using the PC for fault tracing, it provides information on the:
• Module that should be changed.
• Sequence of faults, if more than one unit is faulty.
• Exact time when the fault occurred.
