every 3 ms while the PHASORREPORT block is expecting input every 0.9 ms. The
PHASORREPORT filtering window is designed to receive updated input every 0.9 ms
and therefore the application will fail.
Rule 2:
The same SMAI or 3PHSUM block can be connected to more than one
PHASORREPORT block only if all the connected PHASORREPORT blocks have
similar instance number or only if all the connected PHASORREPORT blocks have
similar settings for SvcClass and ReportRate. Figure

Figure 42 shows an example of correct connection of SMAI and PHASORREPORT
blocks in ACT 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.
