Using front-connected PC

When an internal fault has occurred, extensive information about the fault can be retrieved from the list of
internal events available in the SMS part:
TRM-STAT TermStatus - Internal Events
The list of internal events provides valuable information, which can be used during commissioning and
fault tracing.
The internal events are time tagged with a resolution of 1ms and stored in a list. The list can store up to
40 events. The list is based on the FIFO principle, when it is full, the oldest event is overwritten. The list
cannot be cleared and its content 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.
