Table 5- 51 Sample coding of a parameter number in PKE and IND for P8820, index 16
PKE IND
decimal xx 820 32 16
hex xx 334 20 10
The parameter index is encoded in the second word of the index (IND).

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.
