The server uses CFG-3 scale factor to scale the analog data values. As a result, the clients which
use scale factors in CFG-3 in order to recalculate analog values, will get a better resolution than
using the scale factors in CFG-2.
The following examples show how the scale factor is calculated.
Example 1:
AnalogXRange =
IECEQUATION2446 V1 EN-US
The scale factor is calculated as follows:
sc alefactor
IECEQUATION2447 V1 EN-US
The scale factor will be sent as 1 on configuration frame 2, and 0.1 on configuration frame 3.
The range of analog values that can be transmitted in this case is
+3276.7 .
Example 2:
AnalogXRange =
IECEQUATION2448 V1 EN-US
The scale factor is calculated as follows:
s c 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
+4915.5 .
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
-305181 to -10000000000 and +305181 to +10000000000 .

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:
