PD Description
This parameter is used to specify the structure of the
currently selected process data profile for input and output
data. The individual process data variables are described.
The total list is possible via Sub index 0, a single entry is
possible using a specific Sub index. Sub index 1
corresponds to the least significant (or the element most
recently transferred in the process data stream). When
reading out the entire list, this element is transferred first.
The length of the list is dependent on which process data
profile is selected. A single element has a length of 3 bytes.
