Structure
The IND array (parameter index) is subdivided as follows:

Page index x x IND subindex
IND subindex
The IND subindex array is an 8-bit value that is transferred in the low byte (bits 0 to 7) of the (IND)
parameter index. In the PROFIBUS "variable-speed drives" pro󹪝le, the subindex 󹪝eld is simply
named "Subindex".
Parameter page index
The page index is used to select parameter pages. This enables the PNU value range to the
extended (0 to 1999). The resulting parameter ID then has the value range from 0 to 65,999.
The page index is coded in bits 10 to 15 of the high byte of IND.
Bits 8 and 9 are reserved, and not used.
The page index is de󹪝ned as multiple of 2000. The binary representation is also scrambled. The
exact assignment of the bits is described below.
