Example 2:
AnalogXRange =
IECEQUATION2448 V1 EN-US
The scale factor is calculated as follows:
sc alefac tor
IECEQUATION2449 V1 EN-US
The scale factor will be sent as 1 on configuration frame 2, and 0.15 on configuration frame 3. The
range of analog values that can be transmitted in this case is
Example 3:
Analo gXRange =
IECEQUATION2450 V1 EN-US
The scale factor is calculated as follows:
sc alefac tor
IECEQUATION2451 V1 EN-US
The scale factor will be sent as 3051804 on configuration frame 2, and 305180.43 on configuration
frame 3. The range of analog values that can be transmitted in this case is
-10000000000 and +305181 to +10000000000 .
6.1.3.4 PMU Report Function Blocks Connection Rules in PCM600 Application
Configuration Tool (ACT)
There are 3 important general rules which have to be considered in PCM600 ACT for the
connection of preprocessor blocks (SMAI) and 3PHSUM blocks to PHASORREPORT blocks:
Rule 1:
Only SMAI or 3PHSUM blocks shall be connected to PMU PHASORREPORT blocks and they shall
have the same cycle time, 0.9 ms.
Figure 37
where both function blocks are working on 0.9 ms cycle time.
