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 IEC61850
stack did not succeed in some actions
like reading IEC61850 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 27. Loss of time
synchronization can be considered as a warning only. The IED has full
functionality without time synchronization.

Here, two summary signals appear, self-supervision summary and numerical
module status summary. These signals can be compared to the internal signals as:
