Description
Cable length

Applies to unshielded connection cables.
Cables over 30 m in length must be shielded.

Sampling dura-
tion/rate for measur-
ing values
1 ms
A reading is taken from each input channel
every millisecond regardless of how many
channels are actually in operation
Sampling rate
AI-PT operating
mode
250 ms
In AI-PT operating mode, calculations are car-
ried out according to the millisecond sampling
rate. A new value is available in the user pro-
gram every 250 ms.

If filtering is active, an average is calculated for the set time range. However, a value is still issued dur-
ing the sampling rate interval. For example, if the filter is set to 1,000, the average of the measure-
ments for the last 1,000 ms / 1,000 measurements is issued each millisecond (or, in the case of AI-PT
operating mode, every 250 ms, the average from the last 250 ms / 1,000 measurements).
The filtering can be activated and configured using CODESYS V3. The sampling rate is constant. It can
only be filtered with a whole multiple of the sampling rate.
