The RESTART flag indicates that the data haven’t been
updated by the field since the device’s reset.
Indicates there is a communication failure on te way between
the data origin device and the reports device.
If TRUE the data values are overwritten in the remote
communication devices.
If TRUE the data value is overwritten by the device which
generated this flag. This behavior might occur due to a
working in diagnostic or temporary due ti human intervention
Flag used to signalize and prevent the event communication
channel overload. As oscillations (rapid changes) on the digital
inputs.
This flag should indicates a quality problem, that the value, of
the attribute to which the quality has been associated, is
beyond representation.
This flag should identify that the value cannot be correct due
to out of calibration reference.
This flag should identify that an evaluation function has found
an inconsistency.
This flag should indicates a quality problem, that the the
attribute to which the quality has been associated is beyond
the predefined values capacity.
This flag should indicates that the value doesn’t attend the
declared precission of the source.
A value seems to be outdated. In case an update don’t occur
during a specific time period.
This flag should indicates that a watch function detected an
internal or external failure.
Update blocked by operator.
This must be an additional identifier which can be used to
classify a value being that a test value which won’t be used to
operacional ends.
0 – Good (Trustfull value, means that there is no anormal
conditions)
1 – Invalid (Value doesn’t match the IED’s value)
2 – Reserved (Reserverd)
3 – Questionable (Present value might be not the same from
the IED)
