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 30.
Loss of time synchronization can be considered as a warning only. The IED has full functionality
without time synchronization.
When settings are changed in the IED, the protection and control applications restart in order to take
effect of the changes. During restart, internal events get generated and Runtime App error will be
displayed. These events are only indications and will be for short duration during the restart.
16.2.2 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.

Status Description
READY / FAIL This signal will be active if the Runtime
Engine failed to do some actions with the
application threads. The actions can be
loading of settings or parameters for
components, changing of setting groups,
loading or unloading of application
threads.
READY / FAIL This signal will be active if the IEC 61850
stack did not succeed in some actions
like reading IEC 61850 configuration,
startup etc.
READY / FAIL LON network interface, MIP/DPS, is in
an unrecoverable error state.
READY / FAIL Line Differential Communication Error
status
READY / FAIL Optical Ethernet Module error status
IED will not be operational during applications restart.
