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 21. 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.
13.2.2
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.
