Subindex 0- 255
The array subindex (referred to simply as "subindex" in the PROFIDrive Profile) is
an 8-bit value which is transferred in the high-order byte (bits 8 to 15) of the
parameter index (IND) when data are transferred cyclically via PPOs. The low-
order byte (bits 0 to 7) is not defined in PROFIDrive Profile version 2.0. The low-
order byte of the parameter index is used on MICROMASTER4 to be able to
address additional parameters with a number of >1999.

Bit 15 = PARA PAGE SEL
The array subindex is an 8-bit value which is always transferred in the low-order
byte (bits 0 to 7) of the parameter index (IND) in acyclical data exchange mode.
The Parameter Page Selection task for additional parameters is performed in this
case by the high-order byte (bits 8 to 15) of the parameter index. This structure
conforms to the USS specification.
