Parameter area (PKW area)
For PPO types 1, 2 and 5 for the net data (useful data), a parameter
range with 4 words is also transferred.
The following tasks are possible using the parameter range:
Request parameter value (reading parameters)
Change parameter value (write into parameters)
Request number of array elements
The PKW area comprises the parameter ID (PKE), the sub–index (IND)
and the parameter value (PWE).
