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.
