Qual_validity
(iii)
Qual_validity (61850 signal: No. 301001 3110041005) is a signal provided for a common quality
information. It can be useful if some 'q' attributes (it's defined in Quality type) should belong
to a common quality. Both severe and non-severe errors are included; therefore, that signal
value will be changed whenever errors (including alarm and warning incidents) are detected.
In this quality signal, the Detail quality information—defined in the standard—is not set at
all.

Note:
If non-severe incidents—such as Minor, Alarm, or Warning error are detected in
the automatic supervisions, the IEC61850 interrupts the Qual_Validity as
'questionable (i.e., the string of Qual_Validity is 1100000000000)'.
If severe incidents—such as Serious or Serious (comm) error are detect, the
IEC61850 interrupts the Qual_Validity as 'invalid (i.e., it is 0100000000000)'.
If non-severe and sever incidents occur at the same time, the output of the
Qual_Validiy is 'invalid (i.e., it is 0100000000000)'.
The test mode will be expressed if the Qual_Validiy has a test-bit (that is,
'0000000000010').
The outputs of MINR_ERR and SERI_ERR come from the MNT_LOGIC function
block (see Chapter
Test function block can output the Test Mode signal (see Chapter
