4.3.14.10.5 Standard register
4.3.14.10.5.1 Total active power
Name:
PmeanT
The value in the register equals a fourth of the actual power. The calculation can be performed in either absolute
or arithmetic mode (see register "MeteringMode" <Bit 3>). Each phase can be separately enabled for the power
calculation (see register "MeteringMode" <Bits 0, 1 and 2>).
Data type
Value
Information
INT
-32,767 to 32,767
Resolution 4 W
This value must be multiplied by 4 by the application. Calculation formula for actual power:
Actual total active power = Register value * 4
4.3.14.10.5.2 Total reactive power
Name:
QmeanT
The value in the register equals a fourth of the actual power. The calculation can be performed in either absolute
or arithmetic mode (see register "MeteringMode" <Bit 4>). Each phase can be separately enabled for the power
calculation (see register "MeteringMode" <Bits 0, 1 and 2>).

INT
-32,767 to 32,767
Resolution 4 var
This value must be multiplied by 4 by the application. Calculation formula for actual power:
Actual total reactive power = Register value * 4
4.3.14.10.5.3 Total apparent power
Name:
SmeanT
The value in the register equals a fourth of the actual power. The power is calculated in arithmetic mode. Each

0 to 32767
Resolution 4 VA
This value must be multiplied by 4 by the application. Calculation formula for actual power:
Actual total apparent power = Register value * 4
4.3.14.10.5.4 Total active energy combined
Name:
AEnergyT
Total active energy in forward and backward direction.
Data type
Value
DINT
-2,147,483,647 to 2,147,483,647
Resolution 0.1 or 0.01 CF, depending on the Power Line factor (e.g. kWs)
Internal calculation formula for the total active energy:
AEnergyT = (DINT)(APenergyT - ANenergyT) ... Calculation overflows must be handled in the application
4.3.14.10.5.5 Total reactive energy combined
Name:
REnergyT
Total reactive energy in forward and backward direction.
Data type
Value
Information
DINT
-2,147,483,647 to 2,147,483,647
Resolution 0.1 or 0.01 CF, depending on the Power Line factor (e.g. kWs)
Internal calculation formula for the total reactive energy:
REnergyT = (DINT)(RPenergyT - RNenergyT) ... Calculation overflows must be handled in the application
