Example 7: Configuring the process data read from the drive
PROFIBUS Parameter No. 916 can be used to define which data
is read cyclically from the drive as application-specific process
data.
In the example below, drive parameter 1.04 CURRENT (68h) is
selected to be transmitted by the drive as PZD3. The selection is
in force until it is superseded by another selection.
Subindex (IND) defines which process data word the required
data is transmitted in, and Parameter Value defines which drive
parameter is mapped to that word.
