Interference frequency suppression
At analog input modules, this suppresses interference caused by the frequency of the AC
network.
The frequency of the AC voltage network may interfere with measured values, particularly for
measurements within narrow voltage ranges. For this parameter, the user defines the mains
frequency prevailing on his system.
Smoothing
The individual measured values are smoothed using filtering. The smoothing can be set in 4
levels.
Smoothing time = number of module cycles (k) x cycle time of the module.
The following figure shows the number of module cycles after which the smoothed analog
value is almost 100%, depending on the set smoothing. It is valid for each signal change at
the analog input.
