This displays all DP slaves from which actual value data can be requested. It also
provides the possibility of sharing data via slave-to-slave communication within the same
drive group.

Select the start address of the data of the DO to be read. This is 268 in the example.

may also offset the start address for the request so that data can be read out in the
middle of the DO telegram.
