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 18. 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 BIM error. Binary input module Error
status. Signal activation will reset the
IED
READY / FAIL BOM error. Binary output module Error
status.
READY / FAIL IOM-error. Input/Output Module Error
status.
READY / FAIL mA input module MIM1 failed. Signal
activation will reset the IED
READY / FAIL This signal will be active when there is a
hardware error with the real time clock.
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
