Parameter |
|---|---|---|
|
nBufferLength |
UDINT |
Length of the input buffer |
|
fSampleRate |
LREAL |
Indicates the sampling rate (samples per second) of the input signal. |
|
fMinInputCurrent |
LREAL |
Minimum input value (RMS) of the current. This prevents the calculation of input values that are too small. |
|
nPeriods |
UDINT |
Number of signal periods for calculating the RMS |
