 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).
