PROFINET IO – Communication protocol 83

.
Parameter data transfer examples
The following examples show how parameter data is transferred
using the DP-V1 mechanisms READ and WRITE.
Note:
Only the data block part of the request is presented in the
examples. See section
Read and write blocks
on page
75
.
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 12.04 (0C.04h).
