The useful data structure has been subdivided into the PKW and PZD areas in
order to satisfy different functional requirements of the communication system.

The PKW (parameter identifier value) telegram section can be used to monitor
and/or change any parameter in the converter. The request/response identifier
mechanisms required to do this are described in Section 3.4 "PKW mechanism".

Control words and setpoints (requests: Master → converter) and status words and
actual values (responses: Converter → master) can be transmitted in the process
data area.
The transferred process data do not take effect until the bits used in the control
words, setpoints, status words and actual values have been routed in the converter
as described in Section "Process data connections" of the reference manual.
