Parameter number (PNU)
The complete parameter number (refer to the parameter list) is formed from the
"basis parameter number" PNU1 and the "page parameter number" PNU2. The
following applies:
PNU = PNU1 + 2000 • PNU2
With PNU2 definition:
PNU2
15 14
20 23
The parameter areas are mapped using PNU1 and PNU2 as follows:
Basis parameter number
PNU1
bits 0 – 10 (PKE)

Index
The index (bit 0 to 7), depending on the task, describes a definite element:
desired array element in the case of indexed parameters,
desired element of the parameter description,
Special significance of index value 255
For the following requests, the index value 255 has a special significance:
"request parameter descriptive element", or.
for the requests to read/write indexed parameters (= arrays)
Here, the following applies:
Task ID
