cannot be erased.
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.
