Peak value function
Each peak value detection unit can monitor either the
Min peak or the Max peak of one of the module's 4 ana
log input channels. A peak value unit may operate in dif
ferent modes:
S EXPORT: peak values will be continuously updated
S HOLD: last peak value will be "frozen"
S PEAK VALUE: peak value detection enabled
S FOLLOW: peak value detection disabled, i.e. the
channel returns the original signal of the input channel
The following combinations are possible:
RUN MAX PEAK VALUE
HOLD MAX PEAK VALUE
FOLLOW HOLD MAX
This also applies to minima.

Function for Root Mean Square (RMS) calculation
RMS is computed from one of the module’s 4 analog
input channels according to the formula:
