Page index: Offset of parameter number
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 (H word, 3rd word) and PWE2 (L word, 4th word).
A 16 bit parameter value is transferred in PWE2 (L word, 4th word). In this case, PWE1 (H
word, 3rd word) must be set to 0.
