20.5.5.1 Internal signals
Self supervision provides several status signals that give information about the internal
status of the IED. For this reason they are also called internal signals. These internal
signals , available on local HMI under
Main menu/Diagnostics/IED status/General ,
can be divided into two groups.
• Standard signals are always presented in the IED, see table 589 .
• Hardware dependent internal signals are collected depending on the hardware
configuration, see table
590 .

local HMI as
Reasons for activation
FAIL Internal
Fail status
Internal fail This signal will be active if one or more of the
following internal signals are active; LMDERROR,
WATCHDOG, APPERROR, RTEERROR, or any of
the HW dependent signals
WARNING Internal
Warning
status
Internal
warning
This signal will be active if one or more of the
following internal signals are active; RTCERROR,
IEC61850ERROR, TIMESYNCHERROR
RTCERROR Real Time
Clock
status
Real time
clock
This signal will be active when there is a hardware
error with the real time clock.
TIMESYNCHERROR Time
Synchroniz
ation
status
Time synch 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.
RTEERROR Runtime
Execution
Error
status
Runtime
execution
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.
IEC61850ERROR IEC 61850
Error
status
IEC61850 This signal will be active if the IEC 61850 stack did
not succeed in some actions like reading IEC 61850
configuration, startup, for example
DNP3 DNP3 error
status
DNP3 This signal will be active when DNP3 detects any
configuration error during startup.
LMDERROR LON/Mip
Device
Error
status
SLM301 LON network interface, MIP/DPS, is in an
unrecoverable error state.
