Data types:
4.10.57 Sine (only for DAC8 modules)
Frequency of sine signal in Hz
Phase of sine signal in degrees
Description: A sinusoid voltage signal having the specified frequency and phase is output. The sine
signal's amplitude is 10 V. Allowed frequency settings are: 1Hz ... 1000Hz (1 kHz). Allowed phase settings:
0° ... 359° (degrees). The result clock pulse is fixed at 0.1 ms.
The sine signal's period can only be multiples of 0.1ms.
The sine signal is generated with a resolution of 0.1ms. The higher the sine's frequency, the more
coarsely the ideal form is approximated. If the signal is analog output, the staircase-shaped signal
generated by the DA-converter is slightly filtered (at 5kHz). The resulting curve shape resembles a sine at
high frequencies, but at lower frequencies the quality is quite high.
The phase is defined in relationship to other channels created alongside by the module.
Data types:
4.10.58 Slope limiting
Description: Slope-limiting is performed on the input channel's sample values. The maximum difference
in value between two consecutive sample values is limited to the maximum increment specified.
Notes: The maximum increment must be specified in terms of the input channel's physical units. If the
specified maximum increment is 0, the return value is always the input channel's first sample value.

4.10.59 Smoothing based on 2 values
