Technical manual
Individual error signals from I/O modules can be obtained from respective module in
the Signal Matrix tool. Error signals from time synchronization can be obtained from
the INTERRSIG function block via two outputs TSYNCERR and RTCERR .

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 582.
• Hardware dependent internal signals are collected depending on the hardware
configuration, see table 583.

Displayed on Reasons for activation
local HMI as
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
Internal This signal will be active if one or more of the
warning following internal signals are active; RTCERROR,
IEC61850ERROR
Real time This signal will be active when there is a hardware
clock error with the real time clock.
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.
Runtime This signal will be active if the Runtime Engine
execution 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 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 This signal will be active when DNP3 detects any
configuration error during startup.
SLM301 LON network interface, MIP/DPS, is in an
unrecoverable error state.
