HMI Signal Name: Status Description
BOMn READY / FAIL BOM error. Binary output module Error
status.
IOMn READY / FAIL IOM-error. Input/Output Module Error
status.
MIMn READY / FAIL mA input module MIM1 failed. Signal
activation will reset the IED
RTC READY / FAIL This signal will be active when there is a
hardware error with the real time clock.
Time Sync 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.
Application 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.
RTE 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.
IEC61850 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.
LMD READY / FAIL LON network interface, MIP/DPS, is in an
unrecoverable error state.
LDCMxxx READY / FAIL Line Differential Communication Error
status
OEM READY / FAIL Optical Ethernet Module error status
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
37 . Loss of time synchronization can be considered as a warning only.
The IED has full functionality without time synchronization.
15.2.2 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:
