Rule 3:
This rule is only related to the connection of 3PHSUM block to the PHASORREPORT block. If
3PHSUM block is configured to use external DFT reference (from SMAI reference block), it shall
only be connected to the same PHASORREPORT block instance as the one the SMAI reference
block is connected to. In other words, both the SMAI reference block and 3PHSUM block (3PHSUM
block with external DFT reference) shall be connected to the same instance of PHASORREPORT
block (PHASOR1-32 of Instance number 1 or 2).
