With the PKW (parameter identifier value) part of the telegram, any
parameter in the converter can be observed and/or altered. The
mechanisms of task/reply IDs necessary for this are described later in the
chapter "Mechanisms of PKW processing".
With the process data part, control words and setpoints (tasks: master →
converter) or status words and actual values (replies: converter →
master) are transferred.
The transferred process data only have an effect if the control-word bits,
the setpoints, the status words and the actual values are routed in the
basic unit in accordance with the chapter "Process data wiring".
The following page gives an overview of typical ways of routing process
data to the basic unit. For this routing of the data, the term "process data
wiring" is often used.
The following process data wiring only applies if a technology board has
not been mounted.
If a technology board is used (e.g. T400, T300, T100), the process data
wiring in the manual for the technology board is to be used.
