Also the internal signals, such as INT--FAIL and INT--WARNING can be connected to
binary output contacts for signalling to a control room.
In the IED Status - Information, the present information from the self-supervision function
can be viewed. Indications of failure or warnings for each hardware module are provided,
as well as information about the external time synchronization and the internal clock. All
according to table 16. Loss of time synchronization can be considered as a warning only.
The IED has full functionality without time synchronization.

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.
