blocks in ACT
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).
Figure 43 shows an example of correct connection of 3PHSUM and
PHASORREPORT blocks in ACT where SMAI3 is configured as the reference block
for DFT reference external out (DFTRefExtOut) and 3PHSUM uses external DFT
reference (from SMAI3). Figures
parameters.
