The parameter index is encoded in the second word of the index (IND).
Example: Coding of a parameter number in PKE and IND for P2016, index 3
The master and slave exchange data via the request ID and response ID (AK), a process
that is to take place with the parameter specified in the PKE. The transfer status is
communicated with the response ID.
