Parameterization
With the programming system’s control configurator, a user can define the
measured value refresh rate and averaging.
The specified value is the refresh time to the SmartWire-DT coordinator. An
averaging function, which smooths input signal fluctuations, is associated
with this setting.

The CANopen field bus transmits data event-controlled when-
ever the reading changes.
Reducing the reading refresh rate, for example to 50 ms, can
increase data traffic on the field bus.
