Data types:
4.10.53 Root-mean-square
Channel from whose sample values the moving RMS is to be calculated
Sampling rate of the result channel
Channel containing the moving RMS of the input channel's sample values
Description: The moving RMS (root-mean-square) value, with equal weighting of the values, is taken for
each set of the input channel's sample values within the specified reduction interval. The reduction
interval is given by the result channel's sampling rate (pulse).
The algorithm for calculating the moving RMS is:
The input channel's sample values within the reduction interval are squared and the squares are
summed. The respective result is divided by the amount of samples in the reduction interval and of this
the square root is taken.
Note: The pulse rate of the result channel may not be higher than that of the input channel.
Data types:
4.10.54 SawTooth
Data rate of result channel
Number of points making up a single period; value range: 1 ... 32768.
Starting value, offset of the sawtooth signal
Increment, slope of the offset signal.
Description: Generates a sawtooth signal. The data rate of the return values is given by the clock pulse
specified. The signal's values are arranged in groups of consecutive values; each group's amount of values
is given by 'Number of points', and each group's first value is the value given for 'Start'. The subsequent
values in each group are the sum of the respective last return value and the 'Increment'-value specified.
Notes: Start-value and Increment must be specified in terms of the input channel's physical units.
