where two different SMAI blocks are connected to different PHASORREPORT blocks with different
instance numbers. In this example, as the PHASORREPORT blocks have different instance numbers
and different settings for SvcClass and ReportRate, a separate SMAI block is used for each
PHASORREPORT block.

Figure 43
where the same SMAI block is connected to different PHASORREPORT blocks with different
instance numbers. Such connection will be only correct if both connected PHASORREPORT blocks
have similar settings for SvcClass and ReportRate. If settings for PMUREPORT instances differ for
SvcClass or ReportRate, then PHASOR1 connection in PHASORREPORT1 instance 2 will not be
compliant with IEEE C37.118 standard. The reason is that the filtering in SMAI/3PHSUM block is
adapted according to the performance class (SvcClass) and reporting rate of the connected
instance of PHASORREPORT function block. In this example, SMAI1 will adapt its filtering
