U16_01 signal
(ii)
PLC U16_01 signal (Signal No. 230302 3112011BB0) being originally prepared for general
purpose is also reserved for expressing the other quality information for possible general
purpose. It is configured in the PLC function, but its default signal has not been mapped for
IEC61850 LNs (that is, it is mapped for LNs depending when it is required). The behavior of
U16_01 is almost the same as the behavior of Qual_validity, but the failure and inaccurate of
Detail quality can also be set.

Note:
 The validity of U16_01 signal is only affected by signals of SERI_ERR and
MINR_ERR of from the MNT_LOGIC function block (see Chapter
supervision: Supervision of task operation
 When errors occur, SERI_ERR signal can be generated if Serious and Serious
(Comm) are set for the settings [
 On the other hand, MINR_ERR signal can be generated if Minor, Alarm,
Warning are set for the settings [
 The SERI_ERR signal includes 'invalid' and 'failure' in the detail quality.
 The MINR_ERR signal includes 'questionable' and 'inaccurate'.
 The SERI_ERR and MINR_ERR signals are exclusive one.
 Table 10.3-9 shows the combination of validity and detail quality.
