162 Communication protocol
Parameter data transfer examples (DP-V1)
The following examples show how parameter data is transferred
using the DP-V1 mechanisms READ and WRITE.
Note:
Only the “data unit” part of the SD2 telegram is presented in
the examples. See
PROFIBUS SD2 telegram for SAP 51

Example 1a: Reading a drive parameter (array element)
Drive parameters are addressed so that the drive parameter group
corresponds to the
Parameter index
(PNU), and the drive
parameter number within the group corresponds to the
Subindex
(IND). In the following example, a value is read from drive
parameter number
12.04
(0C.04h).
