Figure 6-3 IND structure acyclic
● The array subindex is an 8-bit value which is in acyclical data exchange mode transferred
in the low-order byte (bits 0 to 7) of the parameter index (IND).
● 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.
Example: Coding for parameter no. in PKE and IND for "P2016, Index 3".
