Name of signal Reasons for activation
Time Synch Error 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 Exec Error 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 Error This signal will be active if the IEC 61850 stack did not
succeed in some actions like reading IEC 61850
configuration, startup, for example.
SW Watchdog Error This signal will be activated when the IED has been under too
heavy load for at least 5 minutes. The operating systems
background task is used for the measurements.
Runtime App Error 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, for
example.
Setting(s) Changed This signal will generate an internal event to the internal
event list if any setting(s) is changed.
Setting Group(s) Changed This signal will generate an internal event to the Internal
Event List if any setting group(s) is changed.
Change Lock This signal will generate an internal Event to the Internal
Event List if the Change Lock status is changed
File System Error This signal will be active if both the working file and the
backup file are corrupted and cannot be recovered.
DNP3 Error This signal will be active when DNP3 detects any
configuration error during startup.
