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.

Hardware interrupt 1 or 2
Enable a hardware interrupt at violation of high limit 1 or 2 or low limit 1 or 2.
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.
