This function is useful only for acyclical data transfer via MSAC_C1. The
transferred data block has the same structure as in the USS specification
(see Fig. 8.2-6). The maximum size of a data block is 206 bytes.
The bit for parameter page selection has the following effect:
If this bit is equal to 1, the parameter number (PNU) transferred in the
PKW task is provided with an offset of 2000 in the CBP and then passed
on.

The parameter value (PWE) is always transferred as a double word (32
bits). In a PPO telegram, only one parameter value can be transferred.
A 32-bit parameter value is composed of PWE1 (most significant word,
3rd word) and PWE2 (least significant word, 4th word).
A 16-bit parameter value is transferred in PWE2 (least significant word,
4th word). In this case, you must set PWE1 (most significant word, 3rd
word) to 0 in the PROFIBUS-DP master.
