The validity range is also used for displaying percentage trend, the per-
centage data reduction and for displaying certain visual elements.
Data reduction
the channel input, processed within the channel and then released at the
channel output. The tolerance specifies the extent of change a signal must
undergo following processing before being output via the interface. In the
example, the processed input value is output only when it differs by more
than 0.1 mA from the preceding value. The
reduces the data rate on the interface and thus assists the PC in the further
processing. The internal processing of measurement values is not affected
by this.
The tolerance value can be expressed as an absolute measurement unit or
as a relative value in relation to the
not have a validity range and, therefore, you can only give the tolerance
value as an absolute measurement unit of the channel.

Persistence
value (refer to data reduction) is stored to a non-volatile memory. The
channel uses this value following a restart or power outage. This function is
particularly important for outputs in order to establish a defined state fol-
lowing power outage.
