Table 17: Explanations of internal signals
Name of signal Reasons for activation
FAIL This signal will be active if one or more of the following internal
signals are active; NUMFAIL, LMDERROR, WATCHDOG,
APPERROR, RTEERROR, FTFERROR, or any of the HW
dependent signals
WARNING This signal will be active if one or more of the following internal
signals are active; RTCERROR, IEC61850ERROR,
TIMESYNCHERROR
NUMFAIL This signal will be active if one or more of the following internal
signals are active; WATCHDOG, APPERROR, RTEERROR,
FTFERROR
NUMWARNING This signal will be active if one or more of the following internal
signals are active; RTCERROR, IEC61850ERROR
RTCERROR This signal will be active when there is a hardware error with the real
time clock.
TIMESYNCHERROR 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 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 This signal will be active if the IEC 61850 stack did not succeed in
some actions like reading IEC 61850 configuration, startup, for
example
WATCHDOG This signal will be activated when the terminal has been under too
heavy load for at least 5 minutes. The operating systems background
task is used for the measurements.
LMDERROR LON network interface, MIP/DPS, is in an unrecoverable error state.
APPERROR 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
