Averaging:
The averaging function is only available for the
analog inputs “2”“ and “3”. No averaging is available
here for the input channels “0” and “1” of the
integrated setpoint potentiomenters of the PS 4-300
and the analog output.
If Averaging has been activated, the mean analog
value of the most recent measured values will be
formed. The number of values from which the
average is taken and the relevant scanning interval
can be set.
When this function is started, the first measured
value of the channel is taken as the mean value.
Averaging is then started from this point on, thus
providing values before the scan time for the set
number of values for averaging has elapsed.
If Averaging has been activated, the analog inputs
%IAW and %IPAW are always mean values. Actual
analog values are only read if Averaging has been
deactivated.
Scan interval: Constant time frame in which the PS 4-300 reads
new measured values for analog channels 0 to 3.
Values from 10 to 50000 ms are permissible.
Number of
values:
Number of the most recent values taken for
averaging. Values 2, 4, 8, 16 are permissible.
Averaging over: Time in which averaging takes place. The product of
Scan interval ⫻ No. of values.
