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
35. 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.

Status Description
READY / FAIL This signal will be active when the
source of the time synchronization is
lost, or when the time system has to
make a time reset.
READY / FAIL This signal will be active if one or
more of the application threads are
not in the state that Runtime Engine
expects. The states can be CREATED,
INITIALIZED, RUNNING, etc.
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.
