348 PROFINET IO – Communication protocol
Example 4: Configuring the process data written to the drive
PROFIdrive parameter 915 (393h) can be used to define which
data is written cyclically to a drive parameter as application-specific
process data.
In the example below, the value of drive parameter 12.06 (0C.06h)
is selected to be taken from PZD3. The parameter will continue to
be updated with the contents of PZD3 in each Request frame until
a different selection is made.
Subindex (IND) defines which process data word the required data
is taken from. Value selects the drive parameter to which that word
is mapped.
