Smoothing
Through the smoothing of analog values, a stable analog signal is made available for further
processing.
The smoothing of analog values is useful when measured values change rapidly.
The measured values are smoothed by means of digital filtering. Smoothing is achieved by the
module calculating mean values from a defined number of converted (digitized) analog values.
You assign smoothing in 4 different levels (none, weak, medium, or strong). The level
determines the number of analog signals used to form the mean value.
The stronger the smoothing is, the more stable the smoothed analog value will be and the
longer it will take until the smoothed analog signal is available after a step response.
Wire break check
Wire break detection is not possible for the current ranges 0 mA to 20 mA and ± 20 mA.
For the current range from 4 mA to 20 mA, provided the wire break check is enabled, a current
value below the input current of I ≤ 1.185 mA is interpreted as a wire break.
If the wire break check is enabled, there is no underflow detection.
10.4.3.2 Diagnostics of the AI 16 x 16 Bit
Introduction
Module faults and channel faults are displayed via the group error display (SF LED) and
signaled via the diagnostic data records 0/1.
