HART can be used to write setpoints to or to read position
or diagnostic information from HART enabled positioners on
control valves.

But it takes either a very high end PLC with HART I/O or a
DCS with HART I/O and the accompanying software application
to do so.

On the other hand, HART is routinely used to configure valve
positioners, for instance, either basic setup or more
sophisticated tasks, like entering a set of values for a
valve position characteristic table.
