Scaling factors
If no floating point numbers can be used, the EL3443 can be operated in "Classic" mode, in which only
integer values are transferred. The following overview shows the scaling factors required to calculate the
actual values from the raw process data values.
If the transformer ratios are not stored in the terminal memory, they must also be subsequently calculated in
the PLC.
If the transformer ratios are stored in the CoE (Index 80n0 PMX Settings) of the terminal, these can be
skipped as scaling factors in the PLC.
Scaling factors for the "Classic" mode of the EL3443-00xx
Values
Calculation
Current
Raw values x 0.0001 A x current transformer ratio
Voltage
Raw values x 0.001 V x voltage transformer ratio
Active power
Raw values x 0.001 W x current and voltage transformer ratio
Apparent power
Raw values x 0.001 VA x current and voltage transformer ratio
Reactive power
Raw values x 0.001 VA x current and voltage transformer ratio
Energy
Raw values x 0.001 Wh x current and voltage transformer ratio
Frequency
Raw values x 0.001 Hz
