Run-time model

The analog signals to the A/D converter is internally distributed into two different
converters, one with low amplification and one with high amplification, see
Reasons for activation
This signal will be active if one or more of the following internal
signals are active; Real Time Clock Error, Runtime App Error,
Runtime Exec Error, SW Watchdog Error, File System Error
This signal will be active if one or more of the following internal
signals are active; IEC 61850 Error, DNP3 Error
This signal will be active if there is a hardware error with the real
time clock.
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.
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.
This signal will be active if the IEC 61850 stack did not succeed in
some actions like reading IEC 61850 configuration, startup, for
example.
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.
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.
This signal will generate an internal event to the internal event list
if any setting(s) is changed.
This signal will generate an internal event to the Internal Event List
if any setting group(s) is changed.
This signal will generate an internal Event to the Internal Event
List if the Change Lock status is changed
This signal will be active if both the working file and the backup file
are corrupted and cannot be recovered.
This signal will be active when DNP3 detects any configuration
error during startup.
