The parameter numbers are assigned to several parameter ranges. The following table
shows which value you must transfer to the page index to achieve a particular parameter
number.

Parameter value (PWE)
The parameter value (PWE) is transferred as a double word (32 bits). Only one parameter
value may be transferred per telegram.
A 32 bit parameter value includes PWE1 (high-order word, third word) and PWE2 (low-order
word, fourth word).
A 16 bit parameter value is transferred in PWE2 (low-order word, fourth word). In this case,
PWE1 (high-order word, 3rd word) must be set to 0.
