Integration time, averaging and bit filter
The following parameters can be configured individually in the Advanced user level and
when selecting the Expert speed setting:
■
Integration time of the measurement (“Sampling Period”)
The integration time, also called output time, defines the time provided for the
statistical analysis via the HDDM process.
An updated measured value is output after each of these measurement cycles is
completed. The integration times available for selection are listed in the preceding
table.
■
“Averaging (analog)” analog output
If required, a moving average can be configured for the analog output. This
requires defining a specific number of measurement cycles in order to determine
the average. This average measured value is output via an analog interface. This
can be used to smooth jumps in a distance value, which results in a more stable
process.
You can choose from the following number of measurement value cycles to be
averaged: off (1; factory setting); 2; 4; 8; 16; 32.
This will not affect the integration or output times. However, the respective output
values are averaged. As a result, equalization of the output value may be delayed
in the event of a change in distance.
■
“BitFilter (switch)” switching outputs
The bit filter for switching outputs determines how often an identical output state
has to recur consecutively before the signal at the switching output changes
accordingly. If the defined number is not reached, the switching output remains
unchanged. This may increase the reliability in the application if the distance value
around the selected switching point fluctuates.
You can chose the following condition of identical, successive output states: off (1;
factory setting); 2; 4; 8; 16; 32.
This will not affect the integration or output times.

User level
There are two different user levels for display operation:
■
Easy: frequently required functions (factory setting)
■
Advanced: almost all functions available in the sensor
A changeover only affects operation of the display. Any time SOPAS ET is in operation or
configurations are being carried out via IO-Link, all functions available in the sensor can
be used.
