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 after how many module cycles the smoothed analog value is

almost 100%, depending on the set smoothing. Is valid for each signal change at the analog

input.

①

None (k = 1)

②

Weak (k = 4)

③

Medium (k = 16)

④

Strong (k = 32)

Low limit 1 or 2

Specifies the low limit threshold that triggers hardware interrupt 1 or 2.

High limit 1 or 2

Specifies the high limit threshold that triggers hardware interrupt 1 or 2.
